Installation Instructions
4. 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 through 5.
5. Before beginning operation of your pump-
ing system, remember: Check that the crank-
case 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.
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
104
0
F (40
0
C,) 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.
IMPORTANT OPERATING CONDITIONS
Failure to comply with any of these conditions invalidates the warranty.

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 out-
line for installation. If you have unique requirements, please contact Giant Industries, Inc. or your
local distributor for assistance.
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 80-90 Industrial Gear Lube Oil (Gi-
ant’s P/N 01154)
Crankcase oil should be changed after
the first 50 hours of operation, then at regular
intervals of 200 hours or less depending on
operating conditions.
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 tempera-
tures.
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.
