INSTALLATION INSTRUCTIONS
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 F, 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
pulsation at drive elements, plumbing, connections,
and other system areas. The use of a dampener
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.
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
conditions invalidates the warranty
1. Prior to initial operation, add oil to crankcase so
that the oil level is between the two lines on the oil
dipstick. DO NOT OVERFILL. SAE 80 Indus-
trial Gear oil may be used. Crankcase oil should
be changed after the first 50 hours of operation,
then at regular intervals of 500 hours or less de-
pending on operating conditions.
°
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 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 desig-
nated 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.
