recommended by Giant Industries, Inc. to further

reduce system pulsation. Dampeners can also

reduce the severity of pressure spikes that occur

in systems using a shut-off gun. A dampener

must be positioned downstream from the un-

loader.

5. Crankshaft rotation on Giant Industries, Inc.

pumps should be made in the direction desig-

nated by the arrows on the pump crankcase.

Reverse rotation may be safely achieved by

followinga fewguidelines availableupon request

from Giant Industries, Inc. Required horsepower

for system

operation can be obtained from the

charts on pages 3 and 6.

6. Before beginning operation of your pumping

system, remember: Check that the crankcase

and seal areas have been properly lubricated per

recommended schedules. Do not run the pump

dry for extended periods of time. Cavitation will

result in severe damage. Always remember to

check that all plumbing valves are open and that

pumped media can flow freely to the inlet of the

pump.

Finally, remember that high pressure

operation in a pump system has many

advantages. But, if it is used carelessly

and without regard to its potential hazard,

it can cause serious injury.

Installation of the Giant Industries, Inc., pump

is not a complicated procedure, but there are

some basic steps common to all pumps. The

following information is to be considered as a

general outline for installation. If you have

unique requirements, please contact Giant

Industries, Inc. or your local distributor for

assistance.

1. The pump should be installed flat on a base to a

maximum of a 15 degree angle of inclination to

ensureoptimumlubrication.

2. The inlet to the pump should be sized for the flow

rate of the pump with no unnecessary restrictions

that can cause cavitation. Teflon tape should be

used to seal all joints. If pumps are to be operated at

temperatures in excess of 140oF, it is important to

insure a positive head to the pump to prevent cavita-

tion.

3. The discharge plumbing from the pump should be

properly sized to the flow rate to prevent line pres-

sure loss to the work area. It is essential to provide

a safety bypass valve between the pump and the

work area to protect the pump from pressure spikes

in the event of a blockage or the use of a shut-off

gun.

4. Use of a dampener is necessary to minimize

pulsationatdriveelements,plumbing,connections,

and other system areas. The use of a dampener

INSTALLATIONINSTRUCTIONS

2. Pump operation must not exceed rated

pressure, volume, or RPM. A pressure relief

device must be installed in the discharge of the

system.

3. Acids, alkalines, or abrasive fluids cannot be

pumpedunlessapprovalinwritingis obtained

before operation from Giant Industries, Inc.

4. Run the pump dry approximately 10 seconds

to drain the water before exposure to freezing

temperatures.

IMPORTANT OPERATING CONDITIONS

Failure to comply with any of these condi-

tions invalidates the warranty

1. Prior to initial operation, add oil to crankcase so

that oil level is between the two lines on the oil

dipstick. DO NOT OVERFILL.

Use Giant Recommended Oil (p/n 01154), or the

equivalent to SAE 85-90W Industrial Grear Lube.

Crankcase oil should be changed after the first 50

hours of operation, then at regular intervals of 500

hours or less depending on operating conditions.

Specifications

Model GP7150A

Consult the factory for special requirements that must be met if the pump is to

operate beyond one or more of the limits specified above.

PULLEY INFORMATION

Pulley selection and pump speed are based on a 1725

RPM motor and "B" section belts. When selecting

desired GPM, allow for a ±5% tolerance on pumps

output due to variations in pulleys, belts and motors

among manufacturers.

1. Select GPM required, then select appropriate

motor and pump pulley from the same line.

2. The desired pressure is achieved by selecting the

correct nozzle size that corresponds with the pump

GPM.

HORSEPOWER INFORMATION

Horsepower ratings shown are the power require-

ments for the pump. Gas engine power outputs must

be approximately twice the pump power requirements

shown above.

We recommend that a 1.1 service factor be specified

when selecting an electric motor as the power source.

To compute specific pump horsepower requirements,

usethefollowing formula:

(GPH X PSI) / 1450 = HP
