INSTALLATION INSTRUCTIONS
4. Use of a dampener is necessary to
minimize pulsation at drive elements, plumb-
ing, connections, and other system areas.
The use of a dampener with Giant Indus-
tries, Inc. pumps is optional, although
recommended by Giant Industries, Inc. to
further reduce system pulsation. Dampen-
ers 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 unloader.
5. Crankshaft rotation on Giant Industries,
Inc. pumps should be made in the direction
designated by the arrows on the pump
crankcase. Reverse rotation may be safely
achieved by following a few guidelines
available upon request from Giant Indus-
tries, Inc. Required horsepower for system
operation can be obtained from the chart on
page 3.
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.
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 ensure optimum lubrication.
2. The inlet to the pump should be sized for
the flow rate of the pump with no unneces-
sary 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 160
0
F, 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 flow 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.
IMPORTANT OPERATING CONDITIONS
Failure to comply with any of these conditions invalidates the warranty.
2. Pump operation must not exceed rated
pressure, volume, or RPM. A pressure
relief device must be installed in the dis-
charge of the system.
3. Acids, alkalines, or abrasive fluids
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 crank-
case so that oil level is between the two lines on
the oil dipstick. DO NOT OVERFILL.
Use Giant Oil # 01154 or the equivalent
SAE 80W - 90 Industrial Gear oil
Crankcase oil should be changed after the
first 50 hours of operation, then at regular inter-
vals of 500 hours or less depending on operating
conditions.
