INTRODUCTION:

GENERAL:

The Model 5410, 5420 and 5440 pumps consist of several components. The following is a list of those major parts

(or component assemblies) and a brief description of their design and function.

IMPELLER:

The impeller is a solids handling type of one piece construction, single suction, enclosed radial flow design with well-rounded leading vanes and tapered toward the trailing edge for a circular flow pattern. Waterways through the impeller have extremely smooth contours, free of sharp corners, so as to minimize rags or stringy, fibrous material from catching or clogging. The impeller is balanced and secured to the shaft by means of a bolt, impeller washer and key. The arrangement is such that the impeller cannot be loosened from torque in either forward or reverse rotation.

VOLUTE:

The volute is matched to the impeller and made of close-grained cast iron. The volute is of one-piece circular constant flow, equalizing pressure design with smooth fluid passages large enough to pass any size solid that can pass through the impeller and has a flange discharge.

FRONTHEAD:

5411, 5421 and 5441 pump frontheads are cast integrally with the volute. Model 4" 541XC and 4" 544XC pumps have a fronthead cast integrally with a combination base elbow as standard. All other models have a separately cast fronthead which directs flow to the eye of the impeller.

BACKHEAD:

Cast as a separate piece, the backhead houses the sealing box which is designed to accept conventional packing or standard mechanical seals without requiring remachining. Casting is tapped so that packing leakage can be piped directly to a drain.

FRAME/BEARING/SHAFT:

Bearing frame is machined for accurate and permanent bearing alignment and houses the bearing/shaft assembly.

The shaft is accurately machined along its entire length and precision ground at bearing locations. A renewable shaft sleeve protects the shaft where it passes through the sealing box area.

541X/544X BASE AND ELBOW :

Pumps are mounted on rigid bases which are open to allow for access to the suction elbow. Bases bolt directly to the volute. Suction elbows include a cleanout opening and have flat-faced flanges conforming to ANSI drilling standards.

541XC/544XC COMBINATION BASE ELBOW :

Base and elbow are integrally cast as one piece with a flat-faced suction flange conforming to ANSI drilling standards.

A hand-hole cleanout is located 180° from the suction flange.

5420 BASE:

Fabricated steel base supports the pump and driver and is designed with large access openings to facilitate grouting.

COUPLING GUARDS:

All 5410, 5420 and 5440 pumps are furnished with coupling guards.




7

NET POSITIVE SUCTION HEAD (NPSH):

NPSH can be defined as the head (energy that causes liquid to flow through the suction pipe and enter the eye of the impeller). NPSH is expressed in two values:

1. NPSH required (NPSHR)

2. NPSH available (NPSHA)

It is essential that NPSHA always be greater than NPSHR to prevent cavitation, vibration, wear and unstable operation.

NPSHR is a function of pump design and therefore varies with the make, size, capacity and speed of the pump. The value for your pump can be obtained from your pump performance curve. NPSHA is a function of your system and may be calculated as follows:

1. When the source of liquid is above the pump: NPSHA = barometric pressure (feet) + static suction head (feet) - friction losses in suction piping (feet) - vapor pressure of liquid (feet).

2. When the source of liquid is below the pump: NPSHA = barometric pressure (feet) - static suction lift (feet) - friction losses in suction piping (feet) - vapor pressure of liquid (feet).

Note: Suction head or suction lift on vertical pumps is measured from the datum elevation plane which is the horizontal plane that passes through the lowest point on the impeller suction vane.

LOCATION AND HANDLING:

The pump should be installed as near to the fluid as possible so a short direct suction pipe can be used to keep suction losses to a minimum. If possible, locate the pump so fluid will flow to the suction opening by gravity. Discharge piping should be direct and with as few elbows and fittings as possible.

Pump and driver should be located in an area that will permit periodic inspection and maintenance. Head and access room should be provided, and all units should be installed in a dry location with adequate drainage.

FOUNDATION:

Pump foundations should have a level surface and be of sufficient mass to prevent vibration and form a permanent rigid support. The most satisfactory foundations are concrete with anchor bolts of adequate size imbedded in the foundation in pipe sleeves with an inside diameter of 2-1/2 times larger than the bolt diameter, which will allow for final accurate positioning of the unit. Recommended anchor bolt design is available from the factory.

INSTALLATION:

GENERAL:

WARNING:

Do not pick up the complete unit by the driver eye bolts or a pump shaft eyebolt.

IMPORTANT:

Pump and driver alignment should be checked throughout the piping and grouting procedures. Once piping connections have been made and grouting completed, alignment corrections are difficult.

GROUTING:

When alignment is correct, the unit should be grouted using a high grade nonshrinking grout. The base is designed to be completely filled with grout.

CAUTION:

Damaging vibration may result if the baseplate is not solidly in contact with the grout bed.

Do not fill the anchor bolt pipe sleeves with grout.

If leveling devices are used, make sure they are not imbedded in grout. Provide access in the grout to the leveling devices (if used) so that they can be backed off or removed after the grout has cured.

Allow the grout to fully cure. Back off leveling nuts (if used) and remove shims and/or wedges. Firmly tighten the foundation bolts so the base is solidly against the grout bed. All pockets and/or holes left by removal of leveling devices are to be filled with grout. Recheck alignment before connecting the piping.




PIPING:

CAUTION:

All piping connections must be made with the pipe in a free supported state, and without the need to apply vertical or side pressure to obtain alignment of the piping with the pump flange.

All piping should be independently supported near the pump so the pipe strain will not be transmitted to the pump casing. Weight of the pipe and contained liquid must be considered in support design. Suction and discharge piping should be one or two sizes larger than the pump suction and discharge sizes, especially where piping is of considerable length. Flexible joints installed in the piping must be equipped with tension rods to absorb piping axial thrust.

Suction pipe must be airtight and sloped upward to the pump flange to avoid air pockets which will impair satisfactory pump operation. Discharge pipe should be as direct as possible with a minimum of valves to reduce pipe friction losses.

A check valve and closing valve should be installed in the discharge line and a closing valve in the suction line.

The check valve, between the pump and closing valve, protects the pump from water hammer and prevents reverse rotation in the event of power failure. Closing valves are used in priming, starting and when the pump is shut down.

Pumps must never be throttled by use of a valve in the suction line.

AUXILIARY PIPING CONNECTIONS:

In addition to primary piping connections, your pump may require connections to the water seal ring, stuffing box drain, baseplate drain, discharge pressure gauges or mechanical seals (if provided). All these connections should now be installed. (Refer to Mechanical Seal section of this manual.)

NOTE: For satisfactory pump operation and life, auxiliary pipe lines must be kept clean.

ROTATION:

Before connecting the motor to the pump, bump start the driver and verify rotation is in the proper direction. Correct pump rotation is indicated by a directional arrow on the pump casing.

VIBRATION AND NOISE LEVELS:

After installation is complete and the pump is put into normal service, a baseline measurement of noise and vibration levels should be made for future reference. Periodic checks should be made, as changes in either of these could indicate problems. Early detection can save expensive repairs and downtime. Refer to Troubleshooting in the operation section of this manual for simple causes and remedies.

Vibration and noise level measurements should be made with the equipment in its normal operating mode, with no unusual background noise present.

INSTALLATION 5410:

LEVELING OF THE PUMP:

Lower the pump onto the foundation and position the base so the anchor bolts are aligned in the middle of the holes in the base.

Set the base on metal shims or metal wedges placed directly under the part of the base carrying the greatest weight, and spaced close enough to give uniform support and stability.

Adjust the metal shims or wedges until the shaft of the pump is vertical. Make sure that all shims or wedges fit firmly between the foundation and the base.

If leveling nuts are installed on the anchor bolts and are used for alignment, follow the same procedure as with shims or wedges. Support the base with additional shims or wedges if necessary. Make sure that all nuts and shim are in firm contact with the base.

Tighten the foundation bolts snugly, but not too firmly and with a good quality machinist’s level check that the shaft is vertical in two vertical planes. Refer to the

Grouting section.




9

FLEXIBLE SHAFT AND DRIVER:

CAUTION:

Carefully read the manufacturer’s installation instructions supplied with the shafting and driver.

Refer to the unit setting plan supplied with your pump.

Install flexible shafting per installation instructions as provided by the shafting manufacturer.

The driver is normally mounted on a high ring base. This base should be mounted on a level foundation and grouted in place. Refer to the Grouting section of this manual.

The high ring base should be leveled prior to grouting. Check the level on the machined surface of the high ring base in two horizontal planes using a good quality machinist’s level.



Lower the unit onto the foundation and position the base so the anchor bolts are aligned in the middle of the holes in the base. Disconnect the coupling halves.

Set the base on metal shims or metal wedges placed directly under the part of the base carrying the greatest weight, and spaced close enough to give uniform support and stability.

Adjust the metal shims or wedges until the shaft of the pump and driver are level. Make sure that all shims or wedges fit firmly between the foundation and the base.

If leveling nuts are installed on the anchor bolts and are used for alignment, follow the same procedure as with shims or wedges. Support the base with additional shims or wedges if necessary. Make sure that all nuts and shims are in firm contact with the base.

Tighten the foundation bolts snugly, but not too firmly, and recheck the shafts for being level before grouting. Motor and pump shafts should also be in close alignment prior to grouting. If not in close alignment, determine the cause for misalignment and correct. Refer to the Grouting section.

IMPORTANT:

Pump and driver alignment should be checked throughout the piping and grouting procedures. Once piping connections have been made and grouting completed, alignment corrections are difficult.

FINAL COUPLING ALIGNMENT:

CAUTION:

Check safety codes, and always install protective guard or shield as required by the various federal, state and local laws and the regulations concerning OSHA.

The final coupling alignment must be made after the piping has been connected. Realign as required. If sufficient adjustment is not achieved, piping may have to be disconnected to properly align the coupling. Reconnect the piping and recheck coupling alignment.

A flexible coupling must not be used to compensate for misalignment resulting from poor installation or temperature changes.

Fairbanks Nijhuis pumps may be supplied with one of several different types of commercial couplings. Refer to coupling drawings and alignment tables in this manual and/or the coupling manufacturer’s installation and alignment instructions which may be supplied with the pump.

PERIODIC ALIGNMENT CHECK:

Coupling misalignment can occur because of shifts in grouting and/or foundations, or because of large objects going through the pump causing shock loading conditions.

Coupling alignment should be checked periodically for changes. Coupling misalignment can lead to or cause bearing failure, coupling failure, shaft breakage and high power consumption.




Refer to the coupling alignment tolerances found in this manual or the coupling manufacturer’s alignment instructions that may have been supplied with the pump.

V-BELT DRIVE:

Pumps coupled to its driver by means of V-belts and sheaves may have been shipped separately from the drive components. Refer to the driver manufacturer’s literature for installation, operation and maintenance instructions.



Lower the pump onto the foundation and position the base so the anchor bolts are aligned in the middle of the holes in the base. Disconnect the coupling halves.

Set the base on metal shim or metal wedges placed directly under the part of the base carrying the greatest weight, and spaced close enough to give uniform support and stability.

Adjust the metal shims or wedges until the shaft of the pump is vertical. Make sure that all shims or wedges fit firmly between the foundation and the base.

If leveling nuts are installed on the anchor bolts and are used for alignment, follow the same procedure as with shims or wedges. Support the base with additional shims or wedges if necessary. Make sure that all nuts and shims are in firm contact with the base.

Tighten the foundation bolts snugly, but not too firmly, and with a good quality machinist’s level check that the shaft is vertical in two vertical planes. Refer to the Grouting section.

DRIVER INSTALLATION:

Mount the driver on the driver pedestal and secure with proper bolting. Units are self-aligning. If you experience difficulty with the coupling connection, contact the factory for assistance prior to starting the pump.

OPERATION:

GENERAL:

This section contains applicable start-up and break-in procedures for operation. Because variations may exist in a particular installation between pumps, drivers and accessory equipment, specific operating instructions are not within the scope of this manual.

CAUTION:

Before starting or operating the pump, read this entire manual and especially comply with the following instructions:

A. Before starting the pump:

1. Rotate the shaft by hand to assure all moving parts are free.

2. Install guards around all exposed rotating parts.

3. Fill the casing and suction line with liquid. The pump may be

primed by using a priming system.

B. Observe all caution or danger tags attached to the equipment.

C. Never run the pump dry as the close running fits within the pump are lubricated by the liquid. Running dry may result in pump seizure.

D. If excessive vibration or noise occurs during operation, shut the pump down and consult the Troubleshooting guide or a Fairbanks Nijhuis representative.

WET WELL DESIGN:

It is required that an evenly distributed flow of nonaerated water be supplied to the pump suction. Improper wet well or sump design, or insufficient suction pipe submergence can result in vortexing which reduces the pump’s performance and can cause severe damage to the pump.




11

NORMAL OPERATING PROCEDURES:

Monitor the following during running cycles:

A. Unit vibration or noise.

B. Driver lubrication.

C. Pump lubrication.

D. Packing box leakage.

Check the following before normal start-up:

A. Driver lubrication (refer to driver operating manual)

B. General condition of all equipment.

PRIMING:

The priming procedure is different for positive and negative suction head systems and the following procedures should be followed:

A. Positive suction head.

1. Open the vent on the highest point of the pump casing.

2. Open all suction valves.

3. Allow liquid to flow from the vent hole until all air bubbles are vented, then close the vent.

4. Pump is now primed.

B. Negative suction head.

1. Install the priming system on the vent at the highest point of the pump casing.

2. Close the discharge valve.

3. Open the suction valve.

4. Start the priming system.

5. Run the priming system until a continuous stream flows through the suction line, then close the vent valve.

6. The pump is now primed.

STARTING THE PUMP:

A. After the pump is primed, the discharge valve closed, and the suction valve open, start the driver according to the driver manufacturer’s instruction.

B. Open the discharge valve slowly to prevent water hammer.

C. Immediately after the pump has been started, check bearing temperature, stuffing box lubrication and operation, and pump noise level. Continue to monitor these values for the first several hours of operation.

BEARING OPERATING TEMPERATURE

These pumps are designed to operate over a wide ambient temperature. The temperature, when measured on the outside surface of the bearing housing, should not exceed 190° F . Temperatures in excess of 190° F may indicate a lack of lubricant or bearing problems. If temperatures exceed this limit, the pump should be stopped and the cause investigated and corrected.

REGULATING/CONTROL PROCEDURE:

Pump stations are usually designed to have the pumps started and stopped automatically using a controller. Since this is a function of station design, the operators should be thoroughly familiar with the system’s operating parameters and the use of the controller.

STOPPING THE PUMP:

A. Disconnect the electrical power and lock out the power to the driver.

DANGER:

B. Check power source with appropriate electrical test equipment to ensure driver cannot accidentally start.

EMERGENCY PROCEDURES:

Many installations are equipped with emergency shutoff switches near the pump location. These locations should be plainly marked and be readily accessible at all times.

The control panel (if used) may be equipped with an emergency stop button or switch.




IMPORTANT:

The operator or persons working around the equipment should be familiar with locations of emergency shutoff points.

A. Emergency Start-up.

1. Open the suction valve.

2. Start the driver.

3. Open the discharge valve.

B. Emergency Shut-down.

1. Shut off the power at the nearest switch.

OPERATING AT REDUCED CAPACITY:

Typical applications cover a wide range of flow rates, and a variable speed driver is often used to adjust the pump capacity, which is taken into consideration by Fairbanks Nijhuis when selecting the pump and impeller trim. Although these pumps are applicable over a wide range of operating conditions, care should be exercised when doing so, especially when actual conditions differ from sold conditions. Always contact your nearest Fairbanks Nijhuis distributor or factory before operating the pumps at any condition other than that for which they were sold.

SEASONAL OPERATING INSTRUCTIONS:

If the pump is located in an area that is subject to below freezing temperatures for extended periods of time and will not be operated enough to prevent freezing, it should be drained to prevent damage to the casing.

TROUBLESHOOTING:

If you have followed the installation and start-up procedures outlined in this manual, your pump should provide reliable service and long life. However, if operating problems occur, significant time and expense can be saved if you use the following checklist to eliminate the most common causes of those problems. Common problems are listed below with suggested remedies shown.

Check every 150 hours for proper operation. Adjust or replace packing as necessary; or replace mechanical seal if so equipped.

Lubricate every 2000 hours or at least once a year.

Clean or replace at least once a year.

Check for changes on an annual basis.



STUFFING BOX:

The stuffing box is equipped with either packing or a mechanical seal. Generally, pumps should be checked for leakage every 150 hours of operation.

PACKING REPLACEMENT:

Use Fairbanks Nijhuis replacement packing. The replacement procedure should be as follows:

A. Stop the pump.

DANGER:

Extreme care should be exercised and steps taken to ensure that the driver cannot be accidentally started. Keep hands, fingers, clothing and any tools away from the coupling. Failure to do so could result in serious personal injury.

B. Unbolt and remove the gland.

C. Use a flexible Packing Tool* with a hook attachment for removal of the packing and a wood screw attachment for removal of the water seal ring. The water seal ring contains several holes for the packing tool.

Note the location of the water seal ring relative to the number of packing rings on each side of the water seal ring.

*The Packing Tool can be purchased from industrial supply or hardware stores. It is not considered a special tool.

D. Clean the packing box and shaft sleeve.

E. Inspect the shaft sleeve for wear or rough finish and replace the sleeve with a Fairbanks Nijhuis sleeve if necessary.

F. Install the new packing and water seal ring.

IMPORTANT:

Stagger the packing end joints 180 degrees and firmly seat each ring of packing as you install it.

Refer to the technical data section (Table #2) in this manual for pertinent packing box dimensions.

G. Slide the packing (212) and water seal ring (10) into the stuffing box on the backhead (34) and install the guard.

H. Reinstall the gland and tighten the gland nuts.

I. Loosen the gland nuts so they can be adjusted with finger pressure to obtain the correct leakage for lubrication after start-up.

PACKING ADJUSTMENT:

Adjustment is accomplished by lightly tightening the gland nuts and then loosening them so they can be adjusted with finger pressure to allow a small flow of liquid to lubricate the packing.

Adjust the packing according to the following procedure:

A. Start the pump and observe the leakage from the stuffing box.

B. The correct amount of flow from the gland should be a stream about 1/8" diameter.

C. Tighten or loosen the gland nuts until the correct amount of leakage is obtained.

D. After installing new packing, it may be necessary to readjust the gland several times before the packing is correctly adjusted.

IMPORTANT:

Do not tighten the gland to stop all leakage. Leakage is necessary to ensure the cooling, flushing and lubrication of the packing and to prevent shaft sleeve damage.

Connect piping from the backhead taps to a suitable drain. Check periodically to ensure the drain is working properly.

E. The stuffing box should be inspected every 150 hours for excessive leakage. If the flow of liquid has increased and cannot be reduced by a slight tightening of the gland, replace the packing and/or shaft sleeve.




15

EXTERNAL WATER FLUSH:

If the pump is handling abrasive material, it is recommended that an external water line be connected to the stuffing box and water injected through the water seal ring.

A flow rate of 2–3 gpm at a pressure of 5–10 psi above the pump discharge pressure should be used.

MECHANICAL SEAL REPLACEMENT:

Refer to the Mechanical Seal section of this manual for general information, including removal and installation procedures.

BEARING LUBRICATION:

Under normal operating conditions, the bearings must be lubricated every 2000 hours of running time or at least once a year regardless of total operating hours.

IMPORTANT:

Any application with abnormal heat, moisture, dust, etc. may require a change in this schedule, and you should refer to a lubrication engineer or the factory for specific instructions.

CAUTION:

Grease recommendations in this manual will provide satisfactory lubrication over a wide temperature range. There is, however, a practical limit and operation of the pump that should be discontinued and the factory consulted if temperatures measured on the outside of the bearing housing exceed 190 degrees F.

GREASE RECOMMENDATIONS:

Recommended grease is a N.L.G.I., No. 2 lithium based multipurpose with a mineral oil viscosity of 950–1250 SUS at 100 degrees F, and 80–82 SUS at 210 degrees F. Suggested greases meeting this specification are listed below:

Manufacturer

Atlantic Richfield

Chevron

Exxon

Gulf

Sinclair

Texaco

Brand Name

ARCO M/P #2

Dura-Lith

Ronex or MP #2

Gulf Crown #2

Litholine MP #2

Marfak 958 or MP #2

Estimated quantities of grease for each bearing is 4 – 5 ounces.

An experienced mechanic will be able to determine the correct amount of grease.

Proceed as follows during lubrication:

DANGER:

Extreme care should be exercised and steps taken to ensure the driver cannot be accidentally started. Keep hands, fingers, clothing and any tools away from the coupling. Failure to do so could result in serious personal injury.

A. Stop the unit, remove the grease drain plug and connect a grease gun to the lubrication fitting.

B. Start the unit and inject grease until the old grease is relieved through the drain opening.

1. If the grease does not relieve at the drain, check for blockage with a mechanical probe.

2. Immediately after lubrication, bearing temperatures may rise above normal level.

C. Continue running the unit until bearing temperatures stabilize at the normal level and grease stops seeping at the grease drain opening.

D. Stop the unit, remove the grease gun, wipe off the relieved grease and replace the plug.

E. Resume normal operation.

IMPELLER RUNNING CLEARANCE:

As the impeller and fronthead wear, the clearance increases causing internal leakage, decreasing pump performance.

The clearance can be adjusted to compensate for wear. Refer to the data section of this manual for nominal impeller clearances. If the desired clearance cannot be obtained, it may be necessary to rebuild the pump.

The clearance may be checked by removing the suction hand-hole cover and placing a feeler (thickness) gauge between the impeller and the fronthead. (Refer to the impeller adjustment drawing illustrations.)




WARNING:

Pumped media may contain items that present health hazards, such as needles and other sharp objects. Always wear puncture-resistant gloves.

T20, T30 AND T40 FRAME PUMPS:

Back off the jackscrews and tighten the capscrews at the bearing housing until the impeller just contacts the fronthead.

NOTE: If the pump is equipped with other than packing or a double mechanical seal, it will be necessary to loosen the seal lock collar to allow movement in the shaft.

Measure the gap between the housing and frame.

Loosen the capscrews and tighten each jackscrew in a crisscross method, 1/8 of a turn at a time until the gap between bearing housing and frame is increased by the amount of required impeller distance.

IMPORTANT:

If the gap is not as specified, repeat this entire procedure until the proper clearance is achieved. Tighten the locknuts to ensure that the jacksrews will remain in the proper position.

T60 and T80 Frame Pumps:

Back off the stud locknuts and capscrews holding the thrust bearing cover (159) and thrust bearing housing (158) to the frame (90).

NOTE: If the pump is equipped with other than packing or a double mechanical seal, it will be necessary to loosen the seal lock collar to allow movement of the shaft.

Measure the gap between the thrust bearing housing (158) and the frame (90).

Adjust the shim pack (186A) thickness between the thrust bearing housing (158) and the frame (90) to achieve the correct impeller clearance.

Tighten the stud nuts and capscrews against the O-rings. Do not compress the O-rings by more than 50%. Recheck the impeller clearance.

IMPORTANT:

If the gap is not as specified, repeat this entire procedure until the proper clearance is achieved.

Tighten the locknuts to the stud nuts to ensure the housing will remain in proper position.

CLEANING THE PUMP

If the pump becomes clogged, it will be necessary to stop the pump and clean out the impeller and volute area.

Proceed according to the following instruction:

A. Stop the pump and lock out the controls so that the pump cannot accidentally start.

DANGER:

Lock out the power and ensure the pump cannot be accidentally started. Check with appropriate test equipment to verify the pump cannot start.

B. Unbolt and remove the cleanout covers in the volute and elbow (if so equipped). Use a hose or long handle to loosen and remove debris. If the material cannot be loosened by a hose, use a scraper and loosen and then flush with a hose.

WARNING:

Do not attempt to clean the pump with bare hands. Pumped media may contain items that present health hazards, such as needles and other sharp objects. Always wear puncture-resistant gloves.

C. Install new gaskets and replace the cleanout covers.

D. Return to normal operating cycle.

Wear Ring Removal:

A. If the wear ring requires replacement, it can be removed by heating it to 350 – 400 degrees F to break the

Loctite ® bond.

CAUTION:


B. The ring may also be ground off if heating fails to affect removal.

IMPORTANT:

Care should be used to avoid damage to the ring set.

Wear Ring Installation:

Because of the required close tolerances, replacement wear rings should be obtained from Fairbanks Nijhuis or their authorized representative.

IMPORTANT:

To ensure proper bonding, thoroughly clean all mating parts with solvent to remove all grease, oil, dirt, etc.

A. Apply a bead of Loctite No. 504 to the impeller completely around the middle of the wear ring fit and press the wear ring in place.

B. Apply a bead of Loctite No. 504 to the fronthead completely around the middle of the wear ring fit and press the wear ring into place.

CAUTION:

To avoid distortion and ensure proper installation, be careful to press the wear rings evenly and completely into place. They should be firmly butted against the corresponding impeller or fronthead shoulder at the bottom of the wear ring fit.




23

Adding Wear Rings:

It is possible to add either or both impeller or fronthead wear rings to pumps that were not so originally equipped from the factory. This work should be done by a qualified machinist experienced in similar machining work. Contact the factory for parts, instructions and correct matching dimensions.

COUPLING REMOVAL AND INSTALLATION:

Refer to the coupling manufacturer’s literature supplied with the pump.

MECHANICAL SEALS:

Mechanical seals covered by these instructions, when properly installed, will give satisfactory performance. To ensure proper installation, these instructions should be read carefully.

Refer to the Technical Data Drawing section of this manual for suggested seal water piping systems: clean water source water flush seal system; deadhead seal water piping system.

DOUBLE MECHANICAL SEALS:

Standard double mechanical seals consist of two stationary seats with O-ring seals and a single spring rotating assembly with O-ring sealing and drive or O-ring sealing and elastomer drive ring.

Removal:

By this time the frame assembly with backhead should have been removed to a clean work area.

A. Remove the capscrews that secure the backhead (34) to the frame (90) and carefully slide it off the shaft sleeve.

B. Remove the solid gland bolts and remove the gland (31).

C. Remove the upper stationary seat (456A).

D. Remove the seal rotating element (456).

E. Remove the lower stationary seat (456A).

F. Inspect all components for damage prior to reassembly. This should include the shaft sleeve. Replace the damaged part(s) or replace with a complete new seal.

Installation:

A. Remove any burrs or nicks on the sleeve (14) and apply a light coat of liquid soap or liquid detergent.

CAUTION:

Seal faces are lapped and polished to a mirror finish. It is imperative that sealing faces be handled with care and kept perfectly clean. DO NOT touch the sealing faces.

B. Slide the solid gland (31), mechanical seal upper stationary seat (456A) and mechanical seal rotating element

(456) over the shaft sleeve (14), being careful not to damage the mechanical seal faces.

CAUTION:

The gland, stationary seat and rotating element must be far enough onto the shaft (4) so as not to interfere with the installation of the backhead (34).

C. Thoroughly clean the sealing box and install the lower mechanical seal stationary seat (456A). Use even pressure to install the seat.

D. Carefully, so as not to damage the stationary seat (456A), slide the backhead (34) over the shaft (4) and shaft sleeve (14) and secure to the frame (90) with capscrews.

E. Without touching the seal faces and using a slight twisting action, push the upper stationary seat and rotating element into the backhead (34) sealing box.

F. When the seal spring can easily be compressed by hand into the sealing box, secure the gland (31) with capscrews to the backhead.

CARTRIDGE TYPE SEAL:

The cartridge type seal consists of a preassembled seal assembly, which reduces handling of fragile seal faces.

Removal:

By this time the frame assembly with backhead should have been moved to a clean work area.

A. Loosen the retainer clips and rotate 90 degrees and tighten the setscrews to secure the seal lock ring to the gland.




B. Loosen the setscrews that secure the lock ring to the sleeve.

C. Loosen the bolts securing the seal gland to the backhead (34) and the capscrews that secure the backhead to the frame (90).

D. Carefully remove the backhead (34).

E. Slide the entire seal assembly from the shaft sleeve (14).

F. Inspect all parts of the seal for signs of wear. If wear is present, replace the entire seal. If only the seal O-rings need to be replaced, refer to the factory for instructions.

Seal Installation:

A. Remove any burrs or nicks on the sleeve (14) and apply a light coat of liquid soap or liquid detergent.

B. Install the seal over the sleeve (14).

C. Install the backhead (34) and secure to the frame (90) with capscrews.

D. Slide the seal assembly into the sealing box of the backhead (34) and secure with gland bolts.

E. Secure the seal lock ring to the sleeve using the setscrews provided.

F. Loosen the setscrews holding the retainer clips in place and rotate 90 degrees and retighten the setscrews.

These clips will be used again if the seal is removed for any reason.

OPERATION:

Special operating techniques are not required when using pumps equipped with mechanical seals. However, there are certain precautions that should be taken.

A. Pumps should never be operated, even to test electrical connections, until the operator knows that there is fluid in the sealing box. In order to check for fluid in the sealing box, loosen seal water piping at the box. Tighten piping only after fluid has started flowing.

Running the seal with an air bound sealing box is the same as running it without fluid. If the seal is set up for deadhead operation, fill the filter, piping and sealing box with clear liquid and vent all air out of the topmost sealing box pipe plug.

B. Some seals will leak slightly when first run. This leakage should cease within a very short period of time.

ROUTINE MAINTENANCE:

Required maintenance at a very minimum as follows:

A. Periodically (150 hours of operation) check to see that the pumped liquid is going through the sealing box out to the wet well or drain.

B. Check that the gland bolts have not loosened and that the gland is flush with the sealing box.

C. Occasionally (4000 hours of operation) clean out the filter on deadhead systems. System must be purged of air and filled with clear liquid as indicated in Operation.
