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

0

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 shut-off 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 charts on pages
3 and 6.

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 the
crankcase so that oil level is between the two
lines on the oil dipstick. DO NOT OVER­FILL.

Use Giant Recommended Oil (p/n 01154),
which is equivalent to SAE 85-90W Industrial

Grear Lube 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.

2. Pump operation must not exceed rated pressure,
volume, or RPM.
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.

A pressure relief device must be

HORSEPOWER RATINGS:

The rating shown are the power requirements for the pump. Gas engine power outputs must

be approximately twice the pump power requirements shown above.

We recommend a 1.15 service factor be specified when selecting an electric motor as the

power source. To compute specific pump horsepower requirements, use the following
formula:

HP = (GPM X PSI) / 1400
