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 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 140
o
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.
4. Use of a dampener is necessary to minimize 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
INSTALLATION INSTRUCTIONS
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 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.
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),
which is 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.
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 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 Industries, 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.
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.
