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 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 shutoff 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 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.
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. Use Giant
recommended oil. 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.
* Important - Check torque bi-weekly on item 49A
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.
