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 installa-
tion. 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 inclina-
tion 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
0
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, connec-
tions, and other system areas. The use of a
dampener with Giant Industries, Inc. pumps is
optional, although recommended by Giant
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 Indus-
tries, Inc.
4. Run the pump dry approximately 10
seconds to drain the water before exposure to
freezing temperatures.
1. Prior to initial operation, add oil to crank-
case so that oil level is between the two lines on
the oil dipstick. DO NOT OVERFILL. SAE 80
or SAE 90 Industrial Gear (p/n 01154) 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 depending
on operating conditions.
NOTE: Contact Giant Industries for Service School Information. Phone: (419)-531-4600
Industries, Inc. to further reduce system pulsa-
tion. 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 ob-
tained from the charts on pages 3-4.
6. Before beginning operation of your pump-
ing system, remember: Check that the crank-
case and seal areas have been properly lubri-
cated per recommended schedules. Do not run
the pump dry for extended periods of time.
Cavitation will result in severe damage. Al-
ways 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 opera-
tion 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.
