User manual HAIGHT PUMPS HAIGHT POSITIVE DISPLACEMENT ROTARY GEAR PUMPS

[. . . ] Operating Manual for Haight Positive Displacement Rotary Gear Pumps Pre-Installation 1. Choose a location that is easily accessible for pump servicing. Ensure adequate electrical service is available. Special attention should be given to the suction piping which should be as large, or larger, than the pump intake port. [. . . ] Haight pumps are designed to operate in either direction by simply changing the shaft rotation. Pumps supplied with relief valves are the exception to this rule. Failure to reverse the relief valve components will render the relief valve inoperable. The procedure for reversing the flow direction in the relief valve is covered in the Assembly and Disassembly instructions. Bedplate mounted pumps and motor combinations are aligned and tested at the factory. Vibration during shipment and/or poor bedplate mounting conditions can cause premature failure or unacceptable noise and vibration. Simple alignment checks can be performed by placing a straight edge on the top and side of the coupling. Improper alignment is indicated by a separation between the coupling and straight edge. Adjust the motor and pump location until any separation disappears in both planes. Install nuts on the foundation bolts to provide location adjustment. Loosely place the bedplate on the foundation bolts. Adjust the bedplate height and location to meet the inlet and outlet piping. Fasten in place with lock washers or lock nuts. Improper suction piping is the leading cause of poor pump performance, including cavitation, noisy operation, inadequate performance, and premature pump failure. Particular care should be taken to avoid long, restricted pipe runs, the use of elbows, tees, valves, or other flow devices within twelve (12) pipe diameters of the pump inlet. Inlet piping should be at least equal to the pump inlet size. The discharge piping arrangement is somewhat less critical than the inlet side, however, good engineering practice, as defined by the Hydraulic Institute, should be followed. Pumps are not designed to be used as piping system support devices. Piping systems should have adequate, independent hangers to provide support. Again, the Hydraulic Institute offers guidelines for proper pipe support design. Seals. Haight Pump offers three standard type seals, each with specific operating characteristics. · Lip seals: Available in Buna-N, Viton, Teflon, Silicone, and Kalraz, and as either single or double seals. [. . . ] Buyer will also pay Baker any collection fees and reasonable attorneys fees incurred by Baker in enforcing this agreement or defending against any claim for breach of this hereunder.
