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.
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.
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.
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
160o F, it is important to insure a positive head
to the pump to prevent cavitation.
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.
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 hazards, it can cause serious injury.
2. Pump operation must not exceed rated pressure, volume, or RPM. A pressure relief device
must be installed in the discharge of the system.
Failure to comply with any of these
conditions invalidates the warranty
3. Acids, alkalines, or abrasive fluids cannot be
pumped unless approval in writing is obtained
before operation from Giant Industries, Inc.
1. Prior to initial operation, add oil to crankcase
so that the oil level is between the two lines on
the oil dipstick. DO NOT OVERFILL. Giant
Recommended 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. Run the pump dry approximately 10 seconds
to drain the water before exposure to freezing
