HEALTH HAZARD exists if pump is used to pump water after it has been used to pump fuel. Do not pump water after the pump has been contaminated by pumping fuel.

SERIOUS INJURY may result if the engine is not turned off during service or maintenance.

may result if engine is not shut down when inspecting alternator.

could occur if you attempt to pump any liquids for which this pumping unit has not been designed. The pumping unit has been designed to pump water or petroleum-based fuels with specific gravities between 0.72

and 1.0.

SEVERE INJURY may result from contact with the rotating cooling blower or V-belt. When it is necessary to make inspections in this area, be aware of the blower and V-belt position, or turn engine off.

EXPLOSION HAZARD exists when smoking or using open flame or spark-producing equipment in the vicinity of battery.

exists within 50 feet (15.2 m) of an operating pump unit. Smoking within this area creates a fire and explosion hazard.

exists when handling ether cylinder. Ether is highly flammable. Do not use near sparks or open flames. Do not inhale fumes. Do not actuate ether start kit more than once. Overloading the engine air housing with this highly explosive fluid (ether) could result in an explosion.

CAUSTIC CHEMICALS IN BATTERIES may cause serious injury if battery electrolyte (acid) or storage batteries are handled carelessly. If acid is splashed on the skin, wash the affected area immediately with plenty of clean water. If acid is splashed in the eyes, wash immediately with plenty of clean water and get medical attention.

DEATH OR SERIOUS INJURY could occur if diesel fuel is not handled carefully. Use in a well-ventilated area away from open flame, arcing equipment, ignition sources, heaters, or excessive heat. Be certain that fuel lines and connections are secure.

Do not inhale vapor. Do not overfill fuel tank. Engine must be turned off and cooled before refueling. Use proper refueling procedures and equipment to avoid spillage. Do not run engine near open fuel containers. DO

NOT SMOKE.

SEVERE BURNS can be caused by turbocharger and exhaust system heated during operation of the engine. If the engine has been running, do not touch the turbocharger or exhaust system components until they have cooled.

CARBON MONOXIDE (EXHAUST GAS) CAN KILL YOU

Exposure to exhaust gases produces symptoms of headache, dizziness, loss of muscular control, drowsiness, or coma. Brain damage or death can result from severe exposure.

Fumes from engine become concentrated with poor ventilation. Operate engine in a ventilated area only.

While running engine, be alert for fumes. If someone is overcome, expose to fresh air; keep warm and still; give artificial respiration if needed. (Refer to FM21-11.) Seek medical attention. Administer oxygen, if available.

GOOD VENTILATION IS THE BEST DEFENSE AGAINST EXHAUST POISONING.

NOISE HAZARD exists for all personnel within 15 feet (4.57 m) of an operating pumping unit. Personnel must wear approved ear protection equipment. Failure to do so may result in impairment or loss of hearing.

SECTION III. TECHNICAL PRINCIPLES OF OPERATION

1-12 GENERAL.

a.

This section provides a functional description of the pumping assembly for the operator.

b.

The pumping assembly is a skid-mounted diesel engine driven centrifugal mainline pump. The operational output is 800 gpm at 1800 feet of head when pumping liquids with a specific gravity of 0.72. It is designed to pump petroleum products or water at a maximum operational output of 800 gpm. The pumping assembly is directly coupled to a turbocharged diesel engine. Controls are contained in the control panel mounted on the side of the assembly. The pump and engine are mounted on a skid assembly. The pumping assembly consists of the following five major functional units.

(1) Pump Assembly (1)

(2) Engine and Engine Systems (2)

(3) Speed Increaser with Clutch (3)

(4) Control Panel (4)

(5) Coupling Assembly (5)

RIGHT SIDE VIEW

TM 10-4320-307-10

1-13 PUMP ASSEMBLY.

a.

Operation. The pump is of the centerline supported design having an axially split casing with suction and discharge manifolds cast into the lower casing. This design allows ready access to rotating assemblies without removal of suction and discharge piping or disconnecting the pump shaft from the speed increasing gear. The pump has a double suction first stage impeller and opposed second and third stage impellers that provide the pump with balanced thrust. This arrangement of three stages minimizes hydraulic pressure against the mechanical seals while also providing axial hydraulic balance. The double volute design of the pump maintains radial hydraulic balance. After the pump is primed and pumping begins, fluid flow is as follows:

(1) Fluid in the supply piping enters the suction manifold.

(2) The fluid enters the pump casing and the double suction first stage impeller.

(3) The impeller rotating at high speed throws the fluid outward from the center of the impeller. This creates a partial vacuum at the center of the impeller, drawing additional fluid from the suction manifold.

(4) The fluid forced out by the first stage impeller passes through a crossover to the second stage impeller.

(5) As fluid passes to the second stage impeller, two cyclone separators divert pumped fluid to the pump seals. The cyclone separators supply the mechanical seals with clean fluid and at the same time return contaminated fluid to the pump suction manifold.

(6) The fluid passes to the second stage impeller and is forced outward from the center of the impeller into a cross-over to the third stage impeller.

(7) From the third stage (center) impeller, the fluid is forced through the discharge manifold into the discharge piping.

(8) As the sequence continues, pump speed may be adjusted between 1270 and 3459 rpm by varying engine speed from 770 to 2100 rpm.

(9) With a fixed piping system, increasing pump speed will increase pump capacity and head. At a fixed pump/engine speed, partially closing the discharge valve will reduce capacity and increase head.

1-14 ENGINE AND ENGINE SYSTEMS.

a.

Operation. The engine provides turning force to the pump rotor. The engine is bolted to the skid frame. The pumping assembly engine is a Cummins Model NTTA-855-P450 industrial dual turbocharged diesel capable of providing 450 hp at 2100 rpm while in continuous operation. The engine is equipped with the following major engine subsystems.

(1) Air Intake System. The engine is equipped with a heavy-duty reusable air cleaner. The air cleaner has a primary filter, an ejector valve, and a restriction indicator on its suction piping. The primary filter element, which may be reused, is easily removed and may be cleaned with air or water.

(2) Lubricating System. The engine lubrication system is provided with a pressure relief safety valve to prevent damage to various engine parts and seals. The engine is also provided with a port to sample oil for testing and an oil sump with a plug and drain tube. Under normal conditions, prelubrication of the turbocharger bearings is not required since there is an oil residual in the turbo bearing that will lubricate the turbo on startup. After long storage or following emergency hot shutdown, lubrication is required for all turbocharger and engine bearings. Lubrication of the turbocharger bearings is accomplished using the normal engine lubrication system without tools or disassembly.

(3) Fuel System. The fuel system consists of a precleaner, hand pump, fuel feed pump, injection pump, injectors, and dual fuel filters. The primary filter is a water separating type. Two 3-way valves with corrosion resistant tags marked OFF, UNIT TANK, and AUXILIARY are connected by the fuel supply and return line to a 110-gallon fuel tank.

(4) Cooling System. The engine is equipped with a water pump and heavy duty radiator capable of maintaining the specified coolant temperature during maximum operating conditions. The radiator may be cleaned from the front using compressed air.

(5) Electrical System. The 24-volt electric power necessary to start the engine is provided by four lead acid 12-volt batteries. Pressing the START switch on the control panel activates the engine starter motor and simultaneously opens the fuel system solenoid. A three-phase alternator provides automatic charging of the batteries through a voltage regulator. An auxiliary charging receptacle is provided to charge the batteries from a remote power source.

Section III. OPERATION UNDER USUAL CONDITIONS

2-4 ASSEMBLY AND PREPARATION FOR USE.

a.

The pumping assembly comes fully assembled, ready for use after attaching the suction and discharge hoses.

b.

The operator must know how to perform every operation of which the unit is capable. The following paragraphs contain Instructions on starting and stopping the unit, operation of the pump assembly, and coordinating the basic motions to perform the specific tasks for which the equipment is designed. Since nearly every job presents a different problem, the operator may have to vary given procedures to fit an individual job.

2-5 OPERATING PROCEDURE.

WARNING

Smoking is prohibited within 50 feet (15 meters) of an operating pump unit. Smoking within this area may create a fire and explosion hazard.

All personnel within 25 feet (7.5 meters) of an operating pump unit must wear approved ear protection equipment. Failure to do so may result in impairment or loss of hearing.

NOTE

The operator must know how to perform every operation of which the unit is capable. The following paragraphs contain instructions on starting and stopping the unit, operation of the pump assembly, and coordinating the basic motions to perform the specific tasks for which the equipment is designed. Since nearly every job presents a different problem, the operator may have to vary given procedures to fit an individual job.

a.

Setup instructions. Proper selection of an operating site is impor tant for efficient and trouble free pump operation. Since the pumping assembly is self-contained, it can be removed to the most favorable operating site. Select an operating site with the following characteristics.

(1) Locate unit as close as possible to the liquid to be pumped with the suction (inlet) side toward the source.

Keep both the length of the suction piping and the height of the suction lift as short as possible.

(2) The operating site should be located on a flat prepared surface (concrete, wooden platform or gravel bed) and be within 5 degrees of level in any direction.

(3) Keep the suction and discharge piping within the pump station assembly as short and straight as possible.

(4) Allow adequate space to permit support of the suction and discharge piping where they enter the pump.

b.

Grounding. Ensure the mainline pumping assembly is properly grounded.

c.

Perform before operation PMCS in accordance with Table 2-2.

WARNING

Do not pump water after the pump has been contaminated by pumping fuel. Failure to comply could cause a health hazard.

CAUTION

Do not attempt to pump any liquids for which this pumping assembly has not been designed.

The pumping assembly has been designed to pump water or petroleum-based fuels with specific gravities between 0.72 and 1.0. Failure to comply could cause damage to the pump.

d. Discharge Piping Installation. Ensure the discharge piping is properly installed. Notify unit maintenance if discharge piping is not installed properly or is leak ing.

2-60

TM 10-4320-307-10 e.

Suction Piping Installation. Ensure the suction piping is installed properly. Notify unit maintenance if suction piping is not installed properly or is leaking.

f. Preparation for Starting.

(1) With the clutch disengaged, turn pump shaft manually using the coupling to the gearbox.

Ensure all rotating components are free to rotate.

WARNING

Both supply and return 3-way fuel valves must be aligned to the same selected fuel supply

(auxiliary or unit tank). Alignment to different supplies could cause engine overheating, shutdown from rapid fuel exhaustion, or fuel system over-flow and the associated fire hazards.

CAUTION

If it is necessary to fill the fuel tank, clean any moisture or dirt from around fuel tank filler cap.

(2) Align the two 3-way fuel valves (1) to the selected fuel supply.

CAUTION

Never operate the pumping assembly unless the pump casing is filled to the top of the suction port. The pump will not prime when dry. Extended operation of a dry pump will destroy the seal assembly and cause overheating which could seriously damage the pump.

NOTE

Ensure pump body is filled to top of suction port so pump will prime properly during startup.

2-61

TM 10-4320-307-10

2-5 OPERATING PROCEDURE (CONT).

g.

Priming.

(1) Ensure drain plugs are tightened, suction valve is open, and discharge valve is closed.

(2) Place a catch basin (1) beneath air vent discharge piping (2) located between tool box and fuel tank.

(3) Fully open two lower pump air vent valves (3).

(4) Prime pump with fluid to be pumped.

(5) When fluid exits air vent discharge piping (2), close two lower pump air vent valves (3).

(6) Fully open two upper pump air vent valves (4).

(7) When fluid exits air discharge piping (2), close two upper pump air vent valves (4).

h.

Starting Instructions.

WARNING

CARBON MONOXIDE (EXHAUST GAS) CAN KILL YOU

Exposure to exhaust gases produces symptoms of headache, dizziness, loss of muscular control, drowsiness, or coma. Brain damage or death can result from severe exposure.

Fumes from engines become concentrated with poor ventilation. Operate engine in a ventilated area only.

While running engine, be alert for fumes. It someone is overcome, expose to fresh air; keep warm and still; give artificial respiration if needed. (Refer to FM21-11.) Seek medical attention.

Administer oxygen, if available.

GOOD VENTILATION IS THE BEST DEFENSE AGAINST EXHAUST POISONING.

Do not smoke within 50 feet (15.2 m) of an operating pump unit. Smoking within this area creates a fire and explosion hazard.

All personnel within 15 feet (4.57 m) of an operating centrifugal pump unit must wear approved ear protection equipment. Failure to do so may result in impairment or loss of hearing.

CAUTION

Be sure the pump is primed with liquid before starting the engine. Extended operation of a dry pump will destroy the seal assembly and cause overheating which could seriously damage the pump.

2-62

TM 10-4320-307-10

CAUTION

Do not use ether start kit except in extremely cold weather when engine will not start. See

paragraph 2-8.

To prevent starter from overheating, do not crank engine with starter for more than 10 seconds.

Battery life will be lengthened if 60 seconds is allowed to elapse between starting attempts.

Under any condition, if engine does not start on initial attempt, allow engine rotation to stop completely before again engaging starter.

(1) Engage and then disengage clutch lever.

(2) Set MODE CONTROL switch (1) to MANUAL. Ensure suction pressure is at least 20 psig.

(3) Turn engine ENGINE/PUMP CONTROLLER knob (2) fully counterclockwise.

(4) Place ENGINE STOP switch in push position.

(5) Set POWER ON/OFF switch to ON.

(6) Switch panel light to ON (if required).

(7) Press PRESS TO TEST LAMPS switch and release. Alarm lights should come on and then go off.

(8) Press ALARM RESET switch.

(9) Verify clutch is DISENGAGED (down).

CAUTION

If engine fails to start within 10 seconds, release STARTER switch; do not attempt starting again until starter motor stops turning. Failure to comply with this rule may result in serious damage to the starter motor.

(10) Press ENGINE START switch. Keep switch depressed until engine starts. If the engine fails to start

after four periods of cranking see troubleshooting procedures in Table 3-1.

2-63

2-5 OPERATING PROCEDURE (CONT).

(11) After engine starts, observe ENGINE RPM gauge (3) to verify engine is idling at its set point (approximately 800 rpm).

TM 10-4320-307-10

(12) Observe SUCTION pressure gauge remains at least 20 psig. If suction pressure is less than 20 psig, refer to troubleshooting procedures in Table 3<#106>1.

CAUTION

Maintain engine idle speed until (800-1000 rpm) engine warmup cycle is complete. Failure to do so could damage equipment.

(13) Allow engine to run at idle speed for an engine warmup cycle (engine coolant temperature must be a minimum of 140 F). When engine is ready for full

RPM, adjust pump for full operation (paragraph

2-5i).

i.

Operating Mode.

CAUTION

Ensure step h procedures are strictly complied with before beginning these procedures. Failure to do so could damage equipment.

(1) Engage clutch.

(2) Slowly open pump discharge valve.

(3) Set MODE CONTROL switch to AUTO.

(4) Control discharge pressure by turning ENGINE/PUMP CONTROLLER knob clockwise as required to maintain required discharge pressure.

2-64

TM 10-4320-307-10 j.

CAUTION

Impeller cavitation occurs when engine speed is increased beyond the point of maximum suction vacuum. Cavitation is harmful to the pump unit and should be avoided at all times.

Cavitation is indicated by a very loud cracking noise in the pump housing.

NOTE

Engine speed and pump discharge will vary in accordance with the output demand. When there is no increase in vacuum (suction) as indicated on the suction gauge, maximum pumping capacity has been reached.

In case of automatic shutdown due to low suction pressure turn off POWER ON/OFF switch, close discharge valve and recheck priming procedures.

In case of automatic shutdown due to overspeed, close discharge valve, turn off POWER

ON/OFF switch and follow starting procedures.

Operational Checks.

CAUTION

Pump overheating can occur if valves in the discharge lines are closed, or if lines are otherwise blocked while pump is operating. Operating against blocked discharge lines can bring fluid in the pump to a boil, build pressure, and cause pump to rupture or explode. If overheating occurs, stop pump and allow to cool before servicing.

(1) Check for engine overheating by monitoring control panel gauges for proper readings. See Table 2-3

f.

If pump is stopped for long periods of time in below freezing conditions, remove four drain plugs and drain pump. Crank engine briefly to complete draining. Replace drain plugs.

g.

Cover pumping assembly with weather cover when not in use and shelter from weather, if possible.

2-9 OPERATION IN EXTREME HEAT.

CAUTION

Poor air filtering and restrictions to air and exhaust flows are harmful to engine.

Heat is removed from the engine through engine exhaust, engine oil, and the engine cooling system. When operating in high temperature, observe the following.

a.

Air Cleaner. High ambient temperatures change density of air used by the engine in combustion. Monitor engine's ability to breathe using the air cleaner intake restriction indicator. Notify unit maintenance at first indication of unacceptable restriction of air flow.

WARNING

Death or serious injury could occur If diesel fuel is not handled carefully. Use in a well-ventilated area away from open flame, arcing equipment, ignition sources, heaters, or excessive heat. Be certain that fuel lines and connections are secure.

Do not Inhale vapor. Do not overfill fuel tank. Engine must be turned off and cooled before refueling. Use proper refueling procedures and equipment to avoid spillage. Do not run engine near open fuel containers. DO NOT SMOKE.

b.

Fuel. Fill the fuel tank at the end of each day of operation in order to prevent an accumulation of vapor in the fuel tank. However, do not overfill. Allow room for fuel expansion.

WARNING

Severe injury may result from contact with the cooling fan or fan belt. When it is necessary to make an inspection in this area be aware of the fan and fan belt position, or turn engine off.

b.

Take special care to prevent rust and corrosion. Coat machined surfaces with oil. Remove any rust or corrosion, and cover the exposed surfaces with paint.

2-11 OPERATION IN HIGH ALTITUDES. The mainline pumping assembly will operate normally at elevations up to 9000 feet (2743.2 m) above sea level. Above 9000 feet (2743.2 m), the operating efficiency of the engine is reduced approximately 4 percent for every 1000 feet. Total discharge head will be reduced, and allowance will have to be made in the placement of booster pump stations and pressure regulators by the pipeline design to account for the increase in altitude.

2-12 OPERATION IN SANDY OR DUSTY AREAS. The pumping assembly's doors and covers are designed to protect the engine during periods of blowing sand. When operating the pump unit in this type of environment, observe the following precautions.

a.

Protect the unit from blowing sand and dust as much as possible.

CAUTION

Closely monitor air cleaner intake restriction indicator in sandy or dusty locations.

At first sign of restriction, change filter elements. Inadequate air filtering and excessive restrictions to air and exhaust flows will adversely affect turbocharger life and performance.

b.

Frequently check the air cleaner restriction indicator. If red band appears in window of air cleaner restriction indicator and no damage to system components is found, contact unit maintenance.

c.

Frequently check oil to be sure it is not contaminated. Contact unit maintenance if oil is contaminated.

WARNING



2-72

SECTION III. MAINTENANCE PROCEDURES

3-4 INTRODUCTION.

a.

This section contains maintenance procedures that are the responsibility of the operator.

b.

Operator maintenance is performed by operating personnel before, during, and after pump operation. These activities are limited to replenishment of lubricating oil and engine fuel, inspection of visible operating components, cleaning, and correction of minor deficiencies requiring only simple, readily available tools.

3-5 LUBRICATION. Notify unit maintenance if lubrication is required.

3-6 CLEANING.

a.

General. The following cleaning instructions apply to all components of the pumping assembly.

Special cleaning instructions required for inspection or repair of a particular part are included as cleaning procedures for that part.

WARNING

Cleaning solvent is flammable and potentially dangerous to people and property. Do not use near open flame, sparks, excessive heat, or on hot surfaces. Flash point of P-D-680 solvent is 100° to 138°F (38° to 59°C). Use solvent in a well-ventilated area, and avoid inhaling fumes. If repeatedly exposed to fumes, seek fresh air and immediate medical help. Avoid prolonged exposure of skin to solvent. Wash exposed skin immediately and thoroughly.

CAUTION

Nonmetallic parts fabricated from rubber, plastic, fabric, and other organic materials cannot be haphazardly cleaned with solvent. Solvent will deteriorate some parts containing organic materials sufficiently to render further use of such parts undesirable. Where solvent cleaning is recommended for such parts, application must be brief, and solvent must not be allowed to remain on the surface.

b.

Cleaning Processes and Materials. Cleaning procedures for parts of this equipment are relatively simple and a high degree of surface cleanliness is not required for most parts. The usual process specified is hand cleaning in solvent. The solvent required is a neutral clear petroleum distillate, free of undissolved water and other matter, and known commonly as dry cleaning solvent (P-D-680). Check the solvent periodically for dirt, and replace the solvent whenever contamination causes unsatisfactory cleaning or reaches two percent by volume of the solvent. Parts for which solvent cleaning is not recommended are usually wiped clean with a cloth or washed with a solution of mild soap and water. Immediately after any cleaning process employing a liquid, parts must be thoroughly dried to prevent corrosive action by residual cleaning liquid. Dry the parts with filtered, oil-free, moisture-free, compressed air.

c.

Standard Cleaning Procedures. The following standard procedures are to be followed in cleaning similar parts in the equipment.

WARNING

Use approved personnel protective equipment to protect eyes and face when using compressed air for cleaning, cooling, or drying. Do not direct airstream toward yourself or toward another person.

Maximum allowable air pressure is 30 psi.

(1) Small Metal Parts. Clean small metal parts by placing them in a fine mesh wire basket and immersing and agitating them in solvent for at least 1 minute. If excessively dirty parts resist cleaning by immersion, brush with a stiff bristle brush in solvent. Remove basket from solvent, drain off excess solvent, and blow dry with compressed air.

(2) Large Metal Parts. Clean large metal parts by wiping with solvent-saturated cloths and, if necessary, scrubbing with a stiff bristle brush. Clean parts that are exceptionally dirty by emulsion soak or emulsion spray methods. Dry parts by blowing with compressed air.

This fine document...

Was brought to you by me:

Liberated Manuals -- free army and government manuals

Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly available information, slap “watermarks” and other junk on it, and sell it.

Those masters of search engine manipulation make sure that their sites that sell free information, come up first in search engines. They did not create it...

They did not even scan it... Why should they get your money? Why are not letting you give those free manuals to your friends?

I am setting this document FREE. This document was made by the US
