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 160
0
F, it is important to insure a positive head
to the pump to prevent cavitation. See NPSH curve.
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.
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 90 Industrial gear 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.
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 charts on
pages 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.
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.
