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

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.
oil level is between the two lines on the oil dipstick. DO
NOT OVERFILL.
Use SAE 80-90W Industrial Gear Lube Oil (p/n
01154)
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.
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 guide-
lines 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 recom-
mended 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.

or RPM. A pressure relief device must be installed in the
discharge of the system.
