1 Manual 4804 Rev C p/n 004804 0000

Introduction

Consult factory for alternate seal con ¿ gurations.

When the nameplate model designation is followed by the letters “HT,” the pump has an operating temperature limit of 220°F (104°C). Direct all inquiries to Tuthill Vacuum & Blower Systems, and reference the model and serial number of the pump.

SUITABLE APPLICATIONS

Kinney Liquid Ring Vacuum Pumps (KLRC) are reliable non-pulsating pumps. KLRC pumps are two-stage con ¿ guration, suitable for operation down to 30 Torr absolute/39.99 mbar

(approximately 29 inches Hg. vacuum reference

30-inch barometer), when sealed with 60°F (16°C) water.

Standard pumps with stainless steel impellers

(designated with material codes F or C) are suitable for operation with sealant temperatures up to 160°F (71°C). Bronze impeller pumps

(designated with material code B) and pumps with “HT” following the Model designation on the nameplate are suitable for operation with sealant temperatures up to 220°F (104°C). Consult

Tuthill Vacuum & Blower Systems for applications requiring operations above 220°F (104°C).

AVOID DAMAGE TO THE PUMP

• Unpack the pump carefully and handle only by methods that will not damage or misalign the pump.

• Do not run the pump dry. Make sure sealant is piped to both seals; see Figure 3-1 on page

7 through Figure 3-4 on page 10 .

• Do not allow sealant in the pump to freeze.

• Do not place any valves or restrictions in the discharge line.

• If the pump and motor are mounted on a base, the unit should only be lifted from the base or by attaching to the base. Lifting the unit by attaching to the pump or motor could disturb the alignment. The crossover manifolding on the

KLRC Series pumps should never be used as an attaching area for lifting.

THEORY OF OPERATION

When the pump is operating, a continuous À ow of sealant liquid is entering the pump and forms a seal between the impeller and the casing ( see

Figure 1-1 on page 2 ). The impeller is offset above the center of the pump casing and as the impeller rotates, pumping action begins in the space between the impeller and casing by

¿ lling and emptying similarly to a reciprocating compressor (engine). Gas inlet and discharge ports are positioned so as to draw gas into the cavity inside the liquid sealed ring during the expansion segment, and to discharge gas along with some liquid during the compression segment.

Figure 1-1 – Cross-Section Liquid Ring Pump

The discharged liquid can be recovered and recirculated through the use of a gas/liquid separator.

An attenuation valve is provided to drain sealant from the pump before starting and to bleed air into the pump to prevent cavitation, which occurs when the pressure is low and the air À ow is minimal. To additionally protect against cavitation, an optional air bleed valve and/or vacuum relief valve can be installed in the suction line.

Water is normally used as a liquid seal but may be unsuitable for some pump applications. Consult

Tuthill Vacuum & Blower Systems before changing to a different liquid in the pump.

Manual 4804 Rev C p/n 004804 0000

PROPERTIES OF SEALANTS

Water is the most commonly used sealant in liquid ring vacuum pumps. Other À uids may be used to obtain process compatibility. In these applications, give special consideration to the properties of the sealant, which may affect pump performance.

Some of the sealant properties to consider are:

• Speci ¿ c Gravity

• Speci ¿ c Heat

• Viscosity

Additionally, the solubility of process gas in the sealant can be signi ¿ cant and should be evaluated, especially if the partial or full recovery system is used. When water is the sealant, its chemical content should be evaluated since certain conditions will affect the service life of the pump. Generally, if water is suitable to drink it is suitable for pump use. Hardness greater than 500

PPM will result in internal plating and fouling of pump parts. Service with hardness of less than

500 PPM depends upon operating temperature and the nature of the mineral deposit. Naturally occurring well water with organic acid of pH5 or higher is generally suitable; however, pH of 7 or higher is preferred. Chemically treated water with sulfur content requires pH7 or higher. Water that has a pH less than 5 should be treated or the pump should have special construction materials.

If internal scaling affects performance, consult a water treatment specialist. Tuthill Vacuum & Blower

Systems recommends that sealants and sealant systems be carefully evaluated. Consult your Tuthill

Vacuum & Blower Systems sales professional or our application engineers to discuss options.

The rated capacity (actual cubic feet per minute

[ACFM]) of a pump is based on the use of incoming seal water at 60°F (16°C). Seal water temperature affects pump capacity. Table 1-1 provides data which, when applied to the following formula, will give the pumping capacity on dry air at water temperature other than 60°F (16°C).

To calculate pumping capacity (ACFM) or to approximate the capacity when using water at temperatures other than 60°F (16°C), the following formulas apply.

SAFETY

GRAPHIC CONVENTIONS USED IN

THIS MANUAL

The following hazard levels are referenced within this manual:

DANGER

Indicates a hazardous situation that, if not avoided, will result in death or serious injury.

WARNING

Indicates a hazardous situation that, if not avoided, could result in death or serious injury.

CAUTION

Indicates a hazardous situation that, if not avoided, could result in minor or moderate injury.

Indicates a situation that can cause damage to the engine, personal property, and/or the environment or cause the equipment to operate improperly.

N OTE: Indicates a procedure, practice, or condition that should be followed in order for the equipment to function in the manner intended.

SAFETY INSTRUCTION TAG

CAUTION

Do not valve or restrict pump discharge opening.

Use oil mist eliminator when operating pump, and ensure adequate ventilation when discharging indoors.

Refer to manual safety instructions.

SAFETY PRECAUTIONS FOR LIQUID

RING PUMPS

Please read the following safety information before operating the vacuum pump.

• Do not operate the pump without the coupling or belt guard properly attached. Disconnect the pump motor from the electrical supply at the main disconnect before removing the coupling or belt guard. Replace the coupling or belt guard before reconnecting the power supply to the pump motor. Operating the pump without the coupling or belt guard properly installed exposes personnel in the vicinity of the pump to risk from rotating drive components.

Manual 4804 Rev C p/n 004804 0000

CAUTION

Do not operate the pump with oxygenenriched gas in the suction line, unless the pump has been properly cleaned, inspected, and certi

ed to be free of hydrocarbon presence and prepared with an inert

uid suitable for the application.

• Oxygen-enriched gas is de ¿ ned as gas of which the constituents include by volume (mol. %) an amount of oxygen greater than that of standard atmospheric air (typically 20-21% by volume).

• If the oxygen content in the gas stream exceeds the proportions found in standard atmospheric air, then it is considered an oxygen-enriched gas and standard mineral oil, synthetic hydrocarbon oil, or other non-inert À uids should not be used.

WARNING

Pumping oxygen-enriched gases with mineral oil, synthetic hydrocarbon oil, or other noninert

À ¿

re or explosion in the pump, resulting in damage or serious bodily injury or death.

• Take precautions to avoid prolonged or excessive exposure to oil mist or process materials emanating from the discharge of the pump.

• Do not allow the pump to discharge into a closed or inadequately ventilated room. Laws and ordinances may pertain to your local area regarding discharge of vapor to atmosphere.

Check local laws and ordinances prior to operation of the pump with discharge to outside atmosphere. Venting of the discharge of an oil mist eliminator to outside atmosphere is highly recommended.

Safety

• Do not restrict the pump discharge in any way, or place valves in the discharge line. The vacuum pump is a compressor and will generate high pressures without stalling the motor when operated at low suction pressures. Excessive pressure could cause pump damage or serious bodily injury.

• Disconnect the pump motor from the electrical supply at the main disconnect before disassembling or servicing the pump. Make sure pump is completely reassembled, the coupling or belt guard is properly installed, and that all ¿ ll and drain valves are installed and closed before reconnecting the power supply.

Accidental starting or operation of the pump while maintenance is in progress could cause pump damage or serious bodily injury.

• Lift pump only by strapping the crossover pipe.

DO NOT lift equipment attached to pump by the pump lifting lugs.

• Do not touch hot surfaces on the pump. In normal operation at low pressures, surface temperatures will not normally exceed 180°F

(82°C). Prolonged operation at 200 Torr

(267 mbar) may cause surface temperatures as high as 220°F (104°C).

Manual 4804 Rev C p/n 004804 0000 5

INSTALLATION

GENERAL

Pumps are partially ¿ lled with a water-soluble rust inhibitor prior to shipment. This solution should be drained or À ushed from the pump. Drain pump by removing drain plugs.

Liquid ring pump units with pump and motor on a common base can be located on any À at, level

À ooring suitable for their weight. The pumps are almost vibration-free and foundation bolting is not normally required. Using elastomer machine mounting pads (vibration controls) is helpful to eliminate minor À oor vibrations. When the base must be bolted to the À oor, it should be shimmed as necessary to avoid base distortion.

DIRECT COUPLED DRIVE

Pumps shipped with the pump and motor directly coupled and mounted on a common base have been aligned prior to shipment and usually require no further alignment. Be sure to check alignment and make any necessary adjustments prior to starting the unit. Generally, when installing À exible couplings, the two shafts must be aligned to within

0.020 of an inch (maximum), and the coupling halves must be positioned on the shafts to be parallel to each other within 0.030 of an inch

(maximum) when measured around the periphery of the coupling halves.

V-BELT DRIVE

Before attempting to tension any V-belt drive, make sure the sheaves are properly aligned. Replace

V-belts in sets and the position the sheaves to allow the belts to be placed in the grooves without rolling them onto the sheaves. The tensioning procedure for all belt types is as follows:

1. With belts properly in their grooves, adjust the sheaves until all slack has been taken up.

2. Start the drive and continue to tension the

V-belt(s) until only a slight bow on the slack side of the drive appears while operating under load conditions.

3. After 24 to 48 hours of operation, the belts will seat themselves in the sheave grooves.

Further tensioning may be necessary as described in step 2.

Slipping (squealing) at start-up is often evidence of insuf ¿ cient tensioning. Belt dressing should not be used on V-belts. Sheaves and V-belts should remain free of oil and grease. Tension should be removed from belts if the drive is to be inactive for an extended period of time.

WARNING

The belt guard or coupling guard must be properly secured in place at all times while the pump is running.

SEALANT RECOVERY SYSTEMS

Figure 3-1 on page 7 through Figure 3-4 on page 10 illustrate sealant con ¿ gurations:

• Once-Through Figure 3-1 )

• Partial Recovery ( Figure 3-2 )

• Full Recovery with Circulating Pump

( Figure 3-3 )

• Full Recovery without Circulating ( Figure 3-4 )

CAUTION

Do not run the pump dry.

Installation

ONCE-THROUGH RECOVERY

The once-through recovery system takes water directly from the water supply through the pump and discharges it directly through a gas/ liquid separator tank to an approved drain. This arrangement is most common on small pumps, in installations where water conservation is not a factor, or where contamination of sealant is not a factor. Optional valving arrangement is designed to conserve sealant À ow and power, and when the pump is operating at high pressure (low vacuum).

The optional system components are described on page 12 .

Figure 3-1 – Piping Schematic Once-Through Recovery System

Manual 4804 Rev C p/n 004804 0000 7

Installation

PARTIAL SEALANT RECOVERY

(PSR)

In the partial recovery arrangement, the pump discharges water and gas into a gas/ liquid separator tank, releasing the gas to the atmosphere and retaining the water. Some water is disposed of through an over À ow and the remainder is retained in the separator tank for recirculation.

Makeup water is added in a quantity necessary to maintain proper sealing water temperature. This is the most commonly used arrangement where sealing liquid conservation is required.

The optional system components are described on page 12 .

Figure 3-2 – Piping Schematic: Partial Sealant Recovery System

8 Manual 4804 Rev C p/n 004804 0000

FULL SEALANT RECOVERY (FSR)

A full sealant recovery system is a closedloop sealing con ¿ guration that employs a heat exchanger (water- or air-cooled) to maintain proper sealing À uid temperature. See Figure 3-3 for piping arrangement. This arrangement is not suitable for prolonged operation at pressure above 400

Torr (533.28 mbar) unless a circulating pump is installed.

Full liquid recovery systems often operate under conditions where condensation would cause the liquid level to rise, making it necessary to drain liquid from the unit in order to maintain the liquid level. The opposite condition can exist whereby liquid evaporation makes it necessary to add makeup liquid to maintain the liquid level. If there are extensive piping ¿ ttings and valves and other

Installation restrictive devices in the sealant line on a full recovery system that does not use a circulation pump, the sealant liquid is induced into the pump under pump suction entirely. For sustained operation above 400 Torr (533.28 mbar), on rapid cycling of pump-down from the atmosphere, a circulation pump may be required. A circulation pump, when added to a full recovery system, maintains proper sealant À ow at all inlet pressure conditions.

The pressure on the sealant gauge will vary depending upon the inlet pressure, from several inches of vacuum to a slightly positive pressure.

Normally, a common supply line is used for both seal liquid and mechanical seal cooling.

The optional system components are described on page 12 .

Figure 3-3 – Piping Schematic: Full Sealant Recovery System with Circulating Pump

Manual 4804 Rev C p/n 004804 0000 9

Installation

Figure 3-4 – Piping Schematic: Full Sealant Recovery System without Circulating Pump

See Speci ¿ cations on page 19 for size of connections. Figure 3-1 on page 7 through

Figure 3-4 on page 10 show the connection locations for suction and discharge gas, sealant water, and shaft seal cooling water of different pump models. Note that connections are different for KLRC-40 and -75 compared to KLRC-125 to

-950. Also shown are the valves and gauges as they should generally be located for any of the piping arrangements. Piping must be no smaller than the pump connection and must be aligned, and may have to be supported, so as not to place a strain on the pump.

Normally it is not necessary to drain a pump to shaft level prior to starting, provided that the incoming sealant À ow was stopped simultaneously with stopping the pump during the last shutdown.

An automatic solenoid valve (normally closed) is convenient for this use. The pump may be manually drained to shaft level by use of the attenuation valve.

As the pump creates its own vacuum it will draw in the required amount of sealant, so that the sealant need not be under pressure when pumping below 400 Torr (533.28 mbar). From 400 to 760

Torr (533.28 to 933.25 mbar), if the pump should operate for an extended period of time, a minimum of 7 PSI pressurized sealant would be required.

Speci ¿ cations on page 19 provides the À ow rates of water at 60°F (16°C) required for standard pumps at standard conditions. Recommended À ow rates should provide an overall temperature rise of

10°F (-12°C) in a water -sealed pump.

Sealant À ow rates and temperatures represent important considerations because of their effect on the heat balance of the pump. If the pump must operate over a broad vacuum range, À ow rates are especially important. With too little water the unit will not pump at full capacity at higher vacuums, and with too much water the horsepower requirement will be excessive in the low vacuum range. Acceptable variations in À ow

10 Manual 4804 Rev C p/n 004804 0000

rates shown in Speci ¿ cations on page 19 are on the order of +10% with no sealant recovery system, +25% to -50% with partial sealant recovery systems. Full recovery systems have an optional sealant circulating pump that may be necessary if sustained operation above 400 Torr (533.28 mbar) is anticipated.

SEALANT FLOW CONTROL

The types of devices used to control the sealant

À ow depend on the sealant arrangement used, the size of the pump, and individual preference. A lowcost constant À ow control device is generally used for no recovery systems and for the supply branch of partial recovery systems. Another method is to install an upstream adjusting valve and an intermediate pressure gauge. The valve can then be adjusted to obtain a speci ¿ ed pressure, thus producing the desired sealing À ow rate and gas inlet pressure. The latter procedure generally provides the most economical sealing À ow rate.

To achieve greater water conservation, the partial recovery system can be used with an optional water miser and the fresh water À ow adjusted for the highest operating temperature compatible with the process.

Installation

With a partial recovery system an optional sealant

À ow control valve actuated by sealant discharge temperature may be used to automatically reduce fresh sealant À ow when water temperatures are low. This will reduce sealant consumption below normal partial recovery À ow rates. Fresh sealant

À ow may also be increased to achieve desired cooling and improve pump performance. In order to reduce sealant water consumption in once-through and partial recovery systems, a solenoid valve may be ¿ tted to the sealant supply line. This valve will be integral with pump start/stop operation, thereby opening the sealant supply line during pump start-up.

An automatic sealant makeup valve and level switch will allow makeup water to be added to maintain a predetermined level in the discharge separator. Conversely, if the system has a large amount of condensables and is adding liquid to the gas/liquid discharge separator, the above valve and switch can be used to activate a drain valve to lower the liquid level in the discharge gas/liquid separator.

When sustained operation is required above

400 Torr (533.28 mbar), or with rapid cycling on small volumes, an optional circulating pump is recommended. This will also apply for long roughing cycles. Also, if the pump RPM is below standard (1,750 RPM), the use of a circulating pump should be considered. High sealant viscosity, and low speci ¿ c heat and density, may require a greater sealant recirculation rate and the use of a circulating pump.

COOLING PIPING FOR

MECHANICAL SEALS

Sealant must be piped to the mechanical seals in order to keep the seal faces cooled and lubricated.

The seals will fail if a suitable À ow of sealant is not supplied. The sealant must be clean and free of particulates. Dirt or grit will cause the seal faces to wear and fail prematurely. Connect the sealant piping to the seals as shown in Figure 3-1 on page 7 through Figure 3-4 on page 10 .

Note that the connections to the pump are different for KLRC-40 and -75 compared to KLRC-125 to

-950.

Manual 4804 Rev C p/n 004804 0000 11

Installation

MANIFOLD PIPING

The suction and discharge ports are distinguishable by arrows on the pump, and are also shown in

Figure 3-1 on page 7 through Figure 3-4 on page 10 . Note that the discharge port on the KLRC-40 and KLRC-75 are at the shaft drive end, whereas on the KLRC-125 to KLRC-950 the discharge port is at the non-drive end. The discharge leg should not have more than 24 inches of elevation from the pump discharge À ange. Too much elevation in this line would cause a buildup of back pressure, overload the motor, and reduce the ef ¿ ciency of the pump. During initial operation, install a screen across the incoming port of the suction end casing to prevent abrasive particles from entering the pump. Remove any accumulation in the screen often enough to prevent restriction of gas À ow. Remove the screen when particulate accumulation no longer occurs.

CAUTION

Newly installed manifolding must be clean, leak-free, and free of any weld slag. When the process produces particulates, which could damage the pump, use a suitable suction line

CAUTION

The pump liquid sealant must not be allowed to freeze in the piping or pump.

ELECTRICAL CONNECTIONS

Standard electrical motors supplied with Kinney

Liquid Ring Pumps are three-phase 230/460 volts 60 Hz, across the line operation. Pump starting loads are low, as null load is developed at maximum RPM. Reduced voltage when starting is not required unless the power use is restricted by the plant power supply. Connect the pump motor and all applicable electrical accessories to a motor controller that has over-current protection (heaters or fuses) based on the full load current multiplied by the service factor as stamped on the nameplate.

There should also be a suitable disconnect switch between the controller and the power supply.

After the motor starter and disconnect switch have been installed, turn the pump by hand to determine that the impeller(s) is free to rotate. Check the rotation by jogging the motor. An arrow on the drive end casing indicates the direction that the pump must rotate. If, after wiring the motor, the pump turns in the wrong direction, reverse any two of the power leads to the motor.

SYSTEM COMPONENTS

The following are some of the components available for installation, either when the pump is ordered or later to be installed in the ¿ eld. Accessories such as solenoid valves and À ow switches can be added to meet particular needs. The air/liquid separator tank can be either the design that is mounted to the À oor or the type that is suspended by the pump manifolding, depending on the application.

INLET ELBOW: Used to adapt vertical pump inlet to horizontal for mounting inlet check valve, etc.

A similar elbow may be used to connect pump discharge separator tank.

INLET VACUUM GAUGE: Used to measure pump inlet vacuum. Standard 3" W dial gauge has brass bourdon tube and reads 0-30" Hg. The gauge is mounted at the pump suction. Stainless is available at an additional cost.

INLET VACUUM RELIEF VALVE: Used to control pump inlet vacuum. If pump capacity exceeds the system requirements at a preset vacuum, then the valve will open and admit ambient air or connected gas. Valve selection is dependent upon desired vacuum setting and pump size.

INLET CHECK VALVE: Used to automatically isolate pump from process chamber when the vacuum pump is shut down, by blocking the back À ow of air and sealant. Valve must be installed in a horizontal position.

FLEXIBLE CONNECTOR: Used to accommodate some motion and misalignment between pump and system. Kinney Flexible Vacuum Connectors with steel À anges and stainless steel bellows are recommended.

INLET SHUT-OFF VALVE: Used to positively isolate pump from process chamber. Ball valves are supplied up to 2" NPT. Butter À y valves are supplied for connections larger than 2" NPT.

Manual 4804 Rev C p/n 004804 0000

SEALANT SOLENOID VALVE: Used to establish sealant À ow (open) when motor is energized, and return to closed position when motor is de-energized.

FLOW CONTROLLERS: Used to establish the sealant À ow rate to the vacuum pump and shaft seals. Recommended À ow controllers are shown in

Table 3-1 on page 11 .

SEALANT CIRCULATING PUMP: Used to circulate recovered sealant. Required for use when operating at high pressure such as frequent cycling, or when operating for prolonged periods above 400 Torr

(533.28 mbar).

STRAINER: Used to ¿ lter solid particles from the sealant.

HEAT EXCHANGER: Used to cool circulated sealant.

INLET AIR EJECTORS

An air ejector may be added to the inlet of a liquid ring vacuum pump to provide an additional pumping stage. The air ejector can achieve signi ¿ cantly lower pressure than is possible with the compound liquid ring pump alone, with no increase in horsepower. The operation of the air ejector is similar to that of a water eductor except that ambient air or recirculated discharge gas is used to provide the motive force for compressing the process gas from system pressure to the liquid ring pump inlet pressure. The liquid ring pump handles both the process gas and the motive gas.

With an air ejector, a suction pressure as low as

3 Torr (3.99 mbar) can be achieved. Using an air ejector, the pumping capacity between cut-in and

10 Torr (13.33 mbar) is about 60% of the pumping capacity at 100 Torr (133.32 mbar), without the air ejector. To increase the pumping capacity above

30 Torr (39.99 mbar), an air shut-off valve may be added. To achieve the full pumping capacity of the liquid ring pump above 30 Torr (39.99 mbar), a valved bypass may also be added. The inlet air ejector can be combined with a liquid ring pump in three ways:

• Air ejector only.

• Air ejector with motive air shut-off valve (manual or solenoid).

• Air ejector with motive air shut-off valve and bypass manifold with valve.

Manual 4804 Rev C p/n 004804 0000

Installation

The standard air ejector is cast iron with a series

300 stainless steel nozzle. All stainless steel ejectors are available upon request.

Figure 3-5 – Air Ejector

Figure 3-6 – Air Ejector Installation

OPERATION

CAUTION

Standard pumps with stainless steel impellers (designated with material codes F or C) are suitable for operation with sealant temperatures up to 160°F (71°C). Bronze impeller pumps (designated with material code

B) and pumps with “HT” following the model designation on the nameplate are suitable for operation with sealant temperatures to

220°F (104°C). Operation with sealant at higher temperatures reduces internal clearances and will cause the pump to fail.

The pump performance curves are shown on the

KLRC Series data sheets, which can be viewed at http://www.vacuum.tuthill.com.The temperature of the sealant is a major factor in determining the base pressure, and in À uences the pumping speed. At lower temperatures the pump capacity increases, and at higher temperatures the pump capacity decreases. The temperature/ef ¿ ciency ratio is not linear and the most pronounced effect is at low pump pressures.

When the pump is supplied with sealant water directly from a water main, the water-regulating valve must be adjusted so that the water enters the pump casing in the order of zero-gauge pressure. If, however, the pump operates at a holding pressure above 400 Torr (533.28 mbar), the sealant water pressure should be increased to about 7 PSIG. It is generally not recommended to run a liquid pump with the suction open to atmosphere for any period of time, as the pump will heat up due to the inability to draw in sealant to dissipate the heat.

STARTING THE PUMP

If the pump has been idle for an extended period of time, turn the pump by hand prior to energizing the motor to determine that the impeller is free to turn.

PRE-START CHECKS

1. Check that the proper electrical power is connected to the control panel via the fusible disconnect.

2. Check that the sealant water supply to the vacuum system is adequate in terms of À ow rate, temperature, and supply temperature.

3. Check that the proper sized inlet and outlet piping is connected to the vacuum system.

Flexible connectors should be used between the pumps and piping to prevent external stresses from being applied to the equipment.

On large-diameter piping, pipe supports should be used to prevent the weight of the piping from stressing the equipment.

4. Fill the separator tank (if applicable) of the liquid ring pump with the correct sealant liquid to the level that corresponds appropriately to the shaft level of the liquid ring pump. At no time should the liquid level be allowed to drop below the sealant outlet connection, which would allow gas to enter the suction of the circulation pump. Maximum sealant level would coincide with the top of the liquid ring pump bearing housing.

Manual 4804 Rev C p/n 004804 0000

5. A liquid level gauge is installed to allow visual monitoring of the sealant level. NOTE: The limitations on what sealant can be used in the liquid ring pump are based on the following considerations: a. The sealant should be compatible with the materials of construction and the process stream so that corrosion, polymerization, or some adverse chemical reaction does not occur.

b. The vapor pressure of the sealant must be compatible with the desired process pressure.

c. Speci ¿ c gravity should be between 0.5 and 2.

d. Speci ¿ c heat should be between 0.3 and 1.

e. Viscosity should be <45 cSt at sealant operating temperature.

system with sealant to the proper level, position the manual valves for start-up. a. Check the globe valve located in the sealant line between the heat exchanger and the liquid sealant. b. Check that the two small valves located in the seal cooling lines leading to the mechanical seals on the liquid ring pump are both fully opened. These valves may be throttled down to halfway open later if slightly higher vacuum is desired, or if sealant pressure is high. Under no circumstances should the valves be closed more than halfway.

7. On initial start-up, or if the pumps have been sitting idle for several weeks, rotate the pumps by hand several rotations to be sure they are mechanically free.

8. Jog the motor to check the proper direction of rotation. Facing the drive shaft of each pump:

The KLRC-40 and KLRC-75 liquid ring pumps rotate counterclockwise. All other models rotate clockwise.

Manual 4804 Rev C p/n 004804 0000

Operation

INITIAL START-UP

1. Turn on the main power by closing the external fusible disconnect switch or circuit breaker.

2. Check that all isolation and discharge valves (if

¿ tted) are in the proper position.

3. Push the START button. The liquid ring pump should start immediately.

4. Turn on the sealant water.

5. Adjust the anti-cavitation valve to obtain best vacuum level without cavitating the liquid ring vacuum pump.

6. Check that the sealant À ow to the mechanical seals is adequate.

7. Check that the cooling water À ow to the liquid ring heat exchanger is adequate by checking the sealant temperature.

8. Check the sealant level in the separator tank. If necessary, add or remove À uid.

PROCEDURE FOR MINIMUM

SEALANT FLOW RATE

The requirements for sealant À ow, as shown in

Speci ¿ cations on page 19 , are the maximum

GPM for once-through, partial and full recovery systems. To determine the minimum quantity of sealant À ow required for a speci ¿ c application, proceed as follows: For once-through and partial sealant recovery systems, with the pump on a system and operating at the desired operating inlet pressure, slowly decrease the À ow of sealant liquid until the inlet pressure begins to À uctuate, and then gradually increase the À ow until the pressure again becomes steady. This is the setting to be used for minimum seal À ow as long as operating conditions remain constant.

Cavitation occurs when there is localized boiling of the sealant. This boiling action causes the formation and collapse of vapor bubbles, and the resultant shock forces cause erosion by tearing out metal particles. The damage can be especially severe in corrosive environments.

Operation

A loud rumbling sound is a sign that cavitation is occurring. It is easily suppressed by raising the inlet pressure above the vapor pressure of the sealant at its operating temperature by bleeding air or another comparable gas into the suction if opening the attentuation valve cannot be used or does not bleed in enough air.

When cavitation occurs, the pump sounds as though it has gravel in it. This noise will commonly occur when the pressure is low and the air or noncondensable gas À ow is slight. Cavitation should be reduced or eliminated by bleeding air into the pump through the attenuation valve. If enough air cannot be bled into the pump to satisfactorily quiet the pump, an air bleed valve should be installed.

Non-condensable gas may be recirculated by adding a return line from the discharge separator tank to the pump inlet bleed valve.

STOPPING THE PUMP

1. Isolate the pump from the process chamber.

2. Shut off sealant liquid supply. ( See Starting the Pump on page 14 .)

3. Shut off cooling sealant to the mechanical shaft seals.

4. Stop the pump.

MAINTENANCE

GENERAL

WARNING

DISCONNECT PUMP FROM ELECTRICAL

POWER SOURCE PRIOR TO MAKING REPAIRS

OR ADJUSTMENTS TO ANY ELECTRIC

COMPONENTS OF THE UNIT. Elementary rules of cleanliness, periodic inspections, and a preventative maintenance policy of the pump will produce optimum performance and prolong the life of the pump.

SHAFT BEARINGS

The two shaft bearings should be lubricated every

1,500 hours of operation or every two months. A high-temperature grease with an extreme-pressure

(EP) additive is recommended. Grease should be added through the grease ¿ tting while the shaft is turning. The temperature of the bearings should not exceed 140°F (60°C) (hot to touch), unless special grease is being used after consulting Tuthill

Vacuum & Blower Systems.

SCALE OR RUST ACCUMULATION

If scale or rust accumulates and hampers the ef ¿ ciency of the pump, remove the scale or rust by circulating an inhibitor selected according to the nature of the buildup.

MECHANICAL SHAFT SEALS

If the mechanical seals are leaking, replace or recondition them. Some mechanical shaft seal manufacturers have a seal reconditioning program, which we recommend where available.

When replacing the mechanical seal, clean the shaft thoroughly where the previous seal may have bonded to the shaft. The assembly drawings and parts lists beginning on page 32 show the mechanical shaft seals that are commonly used on Kinney liquid ring pumps. The seal faces must be protected during installation from particles that may scratch the surfaces. Before installing the elastomers, the shaft and elastomers should be lubricated with a lubricant compatible with the pumping process for ease in installing and better positioning on the shaft.

CAUTION

Do not run the mechanical seal without coolant.

17 Manual 4804 Rev C p/n 004804 0000

Maintenance

PREPARATION FOR STORAGE

If the pump is to be idle for an extended period of time, it should be preserved internally to prevent rust if the sealant liquid is water or water-soluble liquids. The pump can be preserved temporarily

(2 to 3 months) by adding a water-soluble rust inhibitor into the pump. For longer periods of preservation, drain the pump by removing the drain plugs. When the draining is completed and all drain plugs have been replaced, ¿ ll the pump to 1/3 to

1/4 full using Shell Oil Company, VSI, SAE-25

(SAE-33 or SAE-37 can be used) or antifreeze.

Rotate the pump by hand to coat the interior of the pump with oil.

DISASSEMBLY

GENERAL

KLRC liquid ring pumps incorporate two sets of tie-rods, which fasten either stages or ends of the pump to the center housing. This allows independent work on each stage. The stages are referred to as drive end (DE) and non-drive end

(NDE). For models 125 through 525, the suction

À ange and the longer ¿ rst stage are located at the drive end, and the discharge À ange and shorter second stage are located at the non-drive end. For models 40 and 75, which do not have a crossover pipe, the suction À ange and ¿ rst stage are located at the non-drive end, and the discharge À ange and second stage are located at the drive end.

Repair on the pump is most easily accomplished with the pump axis in a vertical position. Adequate support is provided by pump stands as shown in

Figure 8-1 on page 26 . Disassemble a pump only to the extent necessary for repair. See the following applicable disassembly and assembly steps.

DISASSEMBLY PROCEDURE

Remove pump from installation and drive coupling with drive key from pump shaft. Drain sealant À uid from pump by removing all 1/4" NPT drain plugs.

NDE Shaft Seal

1. Position pump vertically on support stand,

NDE up.

2. Remove NDE bearing housing cap.

3. Remove bearing housing À ange screws and use two in threaded holes to push off bearing housing.

4. Remove the loose elastomer À inger, the shaft seal seat and the ball bearing from the bearing housing.

5. Remove the shaft seal head from the shaft.

Because various shaft seal types with different lengths can be used in the seal cavity, some seals require the use of seal spacer washers between seal head and impeller locknut. For identical seal replacement, these spacers must be reused.

N OTE: For NDE shaft seal replacement only, see

NDE Shaft Seal and Bearing Housing on

page 25. For disassembly of the NDE stage only or complete disassembly, see

NDE Stage on page 20.

REASSEMBLY

GENERAL

All pans must be clean. Clean off old sealant ¿ lm at housing interfaces and remove with an effective solvent. All joint and impeller faces must be free of any nicks.

N OTE:

• Standard cast-iron construction

FA and BA pump housing joints are sealed with Loctite Corp./

Permatex Aviation Form - A - gasket liquid sealant 3H, thinning solvent

Denatured Alcohol.

• Stainless steel pumps CD3 are assembled with PTFE glass¿ gaskets in lieu of sealant. Note: Iron pumps designated for hot operation

(220°F [104°C] limit) are assembled with paper shims and gasket liquid sealant 3H.

• Sealant (when used) must be applied lightly on one surface of joint with a small stiff brush. The sealant can must be capped when not in use to avoid solvent evaporation. If needed,

REASSEMBLY PROCEDURE

NDE Impeller/Shaft

1. If the NDE impeller was removed from the shaft, install drive key and impeller on shaft.

Looking at the NDE of the shaft, the curvature of the impeller blades must be clockwise on models 40 and 75 and counterclockwise on models 125 to 525.

N OTE:

• Install and wrench-tighten the impeller nut and, when seated, apply one hammer blow to the wrench.

Then install the impeller locknut and again when seated apply one hammer blow to the wrench.

• If a dummy NDE bearing is not available, ensure that the ball bearing

ts on the shaft bearing journal with a very light tap or slip

2. Temporarily install a dummy or ball bearing and a bearing cap in the NDE bearing housing.

Then attach it to the NDE end casing.

N OTE: To differentiate end casings, note the

DE casing for models 300 to 525 has the under the bearing housing. In models 40 and 75, the supply port is located on the outside periphery of the NDE end casing at centerline height.

NDE Stage

1. Position the NDE end casing/bearing housing assembly on the assembly stand. If the

NDE end plate (with shaped suction port for models 40 and 75, and smaller discharge port for models 125 to 525) was removed, apply sealing compound to the counter-bored sealing face. Note: For stainless steel models, use the PTFE glass¿ lled gasket in lieu of sealant.

Install the plate, full face up, slightly rotating it to distribute sealant (if used), while lining up the bolt holes.

2. Insert the NDE of shaft/impeller assembly into the bearing so the impeller face rests on the end plate. A dummy bearing is helpful for an easy ¿ t at this step.

Manual 4804 Rev C p/n 004804 0000

Reassembly

3. Apply sealing compound to the male end of the

NDE impeller housing. (For 40 and 75 models with two male ends, check the cross-sectional drawing for correct end.) Install it, aligning the cast-in index marks on top of housing and end casing. Tap it with a soft hammer for proper sealing. Then apply sealing compound to the top end face. Note: For stainless steel models, use the PTFE glass¿ lled gasket in lieu of sealant.

4. Place the center housing with tie-rods, drain holes at bottom, onto the impeller housing with tie-rods entering the end casing holes. Align the indexing marks and tap it down.

5. Assemble washers and nuts to tie-rods and tighten in a criss-cross pattern in several incremental steps with a clicker torque wrench.

For example: 30, 40 ft-lbs. The assembly position does not allow easy reading of a dial torque wrench.

DE Stage

1. Install impeller drive key and impeller on shaft.

Looking at the DE of shaft end, the impeller blades must be pointing:

KLRC-40 and 75

Counterclockwise

KLRC-125 to 950

Clockwise

Proceed with retaining washer, impeller nut, and washer locking bend as in step 1 in NDE

Impeller/Shaft on page 23 . Prevent shaft rotation with a spanner wrench at the drive end keyway. (This washer is found on the old-style

KLRC pump only.)

2. Apply sealing compound to the matching end of the DE impeller housing. (For 125 to 525 models with two male ends, align tooling tabs with those on the NDE impeller housing.)

Install it, aligning the top index marks on the center housing. Note: For stainless steel models, use PTFE glass¿ lled gaskets in lieu of sealant.

3. If the DE end plate (with shaped suction and discharge ports for models 125 to 525 and one discharge port for models 40 and 75) was removed from the DE end casing, follow step 1 in NDE Stage on page 23 for its assembly.

Reassembly

4. Place the DE end casing/plate assembly on top of the impeller housing with tie-rods entering the bolt holes and align index marks. Assemble washers and nuts to tie-rods and lightly tighten them.

5. To ensure correct alignment of the feet of both end casings, an alignment bar as shown in

Figure 8-3 on page 28 can be bolted to the end casing feet to get correct radial alignment.

Then loosen one bolt lightly and tighten the tierod nuts as in step 5 in NDE Stage on page

23 .

installed if it was removed.

DE Shaft Seal and Bearing Housing

1. If the lip (oil) seal is damaged during the disassembly process, replace it at this time using the proper tooling.

2. Install shaft seal spacer washer on the shaft against the impeller nut for use with the John

Crane shaft seal, standard in cast-iron pumps

(Kinney version FA and BA). No spacer is used with Flowserve shaft seal, standard in stainless steel pumps (Kinney version CD) or optionally in cast-iron pumps; for example, FD2 models.

3. Remove carbon from seal head, Kinney style “A” only (John Crane Type 21) and push seal elastomer boot onto a very lightly greased (vacuum grease) shaft against the washer, then reinstall carbon with proper notch alignment. When installing Kinney style

“D” (Flowserve type RO), ensure that the drive dowel pin is aligned with and enters the clearance hole in the impeller locknut.

4. Install the shaft seal seat, with lightly greased

(vacuum grease) seal element and lapped surface facing out, into the DE bearing housing

(with attached pump nameplate). Place O-ring into bearing housing À ange groove. Insert

À inger into housing gap, and install both on shaft and against end housing, ensuring proper seating. The shaft seal spring compression will give some resistance. Install bolts with lock washers.

5. Install bearing spacer washer on shaft. Washer thickness is stamped on the front of the DE bearing housing. For example, 57 would indicate 0.057" thick bearing washer. Install the double-row ball bearing on shaft and into housing using proper tooling. Install bearing locknut with spanner wrench, while holding shaft with another spanner wrench in the drive keyway, until hand-tight. Then hammer-tap until solid resistance is felt. Install DE bearing cap with lock washers and screws.

N OTE: On a typical KLRC repair, the factory shim setting should be reused. In the event that the shim is damaged, a shim of the same size can be ordered from the factory. (See

Clearance Check and Adjustment on page

25.)

NDE Assembly Preparation

Invert the pump assembly on the assembly stand.

Remove the temporarily installed bearing housing, bearing cap, and dummy or ball bearing.

N OTE: If continuing with a complete reassembly, skip to NDE Shaft Seal and

Bearing Housing on page 25. If only reassembling the NDE side, see Center

Housing and NDE Stage on page 24.

Center Housing and NDE Stage

1. If the center housing and DE impeller housing were removed, follow assembly steps 2 through 5 in DE Stage on page 23 to reinstall.

2. If the NDE impeller was removed from shaft, reassemble as in step 1 in NDE Impeller/Shaft on page 23 .

3. Position the NDE impeller housing for correct match with center housing and DE impeller housing. Then apply sealing compound to the matching end and install with a slight rotating movement while aligning the cast-in index marks. Note: If the unit is stainless steel, use

PTFE glass¿ lled gaskets in lieu of sealant.

4. If the NDE end plate was removed from the

NDE end casing, reassemble it as in step 1 in

NDE Stage on page 23 .

24 Manual 4804 Rev C p/n 004804 0000

5. Place the NDE end casing/plate assembly on top of the impeller housing with tie-rods entering the bolt holes and align the index marks. Assemble washers and nuts to tie-rods and lightly tighten them.

6. For alignment of feet and tie-rod torque nuts, follow step 5 in NDE Stage on page 23 and

5 in DE Stage on page 23 .

NDE Shaft Seal and Bearing Housing

1. For shaft seal spacer washers, follow step 2 in DE Shaft Seal and Bearing Housing on page 24 .

2. For seal head assembly, follow step 3 in DE

Shaft Seal and Bearing Housing on page

24 .

3. For NDE bearing housing assembly, follow step 4 in DE Shaft Seal and Bearing Housing on page 24 .

4. Install the single-row ball bearing on shaft and seat into bearing housing. To avoid relative displacement of inner and outer bearing races with slight interference ¿ t, use a bearing driver as shown in Figure 8-2 on page 27 . Then install NDE bearing cap with lock washers and screws.

Crossover Pipe

Assemble crossover pipe,with gaskets to both end casings, facing the drive end to the left DE end casing À ange, and the diagonal NDE end casing

À ange. Within the available play of the studs in the

À ange holes, match the À ange outside diameters as best as possible.

Reassembly

Clearance Check and Adjustment

If replacement of casings or housings (end, center, or bearing) occurs during the repair of a KLRC pump, recheck shim thickness. Included in the

KLRC repair kits is one shim of the largest size.

This can be ground to the dimension to achieve the same result. Dummy bearings will be required to accomplish this task. The dummy bearings should be made based on the dimensions of the bearings supplied for the pump model less 0.002" in OD and increased by 0.002" in ID. Mild steel or an equivalent material is acceptable for this. It may be advantageous to provide threaded holes to aid in removal of the dummy bearing.

N OTE: If a shim change is required on a “hot pump” or stainless steel pump, contact the factory for further information.

The required shim dimension can be found as follows:

1. Move the shaft of the assembled pump fully toward the NDE of the pump.

2. With the bearing cap removed and using a depth micrometer, measure to the dummy bearing from the bearing housing surface.

Record the reading. With the assistance of a gear puller, push the shaft completely toward the DE of the pump.

3. Using a depth micrometer, measure to the dummy bearing and record the reading.

4. Subtract the smaller reading from the larger.

This number is the total clearance of the pump.

5. The shim size is one-half of the total clearance within the pump.
