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 restric- tions that can cause cavitation. Teflon tape should be used to seal all joints. If pumps are to be oper- ated at temperatures in excess of 140o F, it is impor- tant 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 un- loader.

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 obtained from the charts on pages 3 & 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 pres

sure operation in a pump system has many advantages. But, ifit 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 condi- tions invalidates the warranty

1.Prior to initial operation, add oil to 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 equiva- lent to SAE 85-90W Industrial Grear Lube. Crank- case 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. 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 temperatures.
