INSTALLATION INSTRUCTIONS

4. Use of a dampener is necessary to mini-

mize pulsation at drive elements, plumbing,

connections, and other system areas. The

use of a dampener with Giant Industries, Inc.

pumps is optional, although recommended by

Giant Industries, Inc. to further reduce system

pulsation. Dampeners can also reduce the

severity of pressure spikes that occur in sys-

tems using a shut-off gun. A dampener must

be positioned downstream from the unloader.

5. Crankshaft rotation on Giant Industries,

Inc. pumps should be made in the direc-

tion designated by the arrows on the pump

crankcase. Reverse rotation may be safely

achieved by following a few guidelines avail-

able upon request from Giant Industries, Inc.

Required horsepower for system operation

can be obtained from the chart on page 3.

6. Before beginning operation of your pump-

ing 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

ow freely to the inlet of the pump.

IMPORTANT OPERATING CONDITIONS

Failure to comply with any of these conditions invalidates the warranty.

2. Pump operation must not exceed rated pres-

sure, volume, or RPM. A pressure relief device

must be installed in the discharge of the system.

3. Acids, alkalines, or abrasive uids cannot be

pumped unless approval in writing is obtained

before operation from Giant Industries, Inc.

4. Run the pump dry approximately 10 seconds

to drain the water before exposure to freezing

temperatures.

1. Prior to initial operation, add oil to the

crankcase so that oil level is between the

two lines on the oil dipstick. DO NOT

OVERFILL.

Use SAE 85-140 industrial gear oil

Crankcase oil should be changed

after the rst 50 hours of operation, then

at regular intervals of 500 hours or less

depending on operating conditions.

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 instal-

lation. If you have unique requirements,

please contact Giant Industries, Inc. or your

local distributor for assistance.

1. The pump should be installed at on a base

to a maximum of a 15 degree angle of inclina-

tion to ensure optimum lubrication.

2. The inlet to the pump should be sized for

the ow rate of the pump with no unnecessary

restrictions that can cause cavitation. Teon

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 cavitation.

3. The discharge plumbing from the pump

should be properly sized to the ow rate to

prevent line pressure 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.

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.

PULLEY INFORMATION

Pulley selection and pump speed are based on a 1725

RPM motor and “B” section belts. When selecting de-

sired 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. Thedesiredpressureisachievedbyselectingthecor-

rect nozzle size that corresponds with the pump GPM.

HORSEPOWER INFORMATION

We recommend that a 1.15 service factor be

specied when selecting an electric motor as the

power source. To compute specic pump horse-

power requirements, use the following formula:

HP = (GPM X PSI) / 1440
