||Haight offers six sizes of pumps in the square flange U-Series. All sizes are available with a bolt-on Relief Valve which can function in either a return to suction, or return to tank mode. All U-Series pumps are interchangeable with earlier D & DR Series pumps.
Compact, rugged, and easy to maintain, these pumps are ideally suited to close-coupled mounting to the motor or footed mounting. Haight Pumps bolt-on footed brackets match standard NEMA motor height, eliminating pump or motor height, eliminating pump or motor shimming. Each bracket size is designed to align the pump and motor shaft heights without shim blocks.
All Series U Square Flange Pumps feature:
- standard motor speeds, eliminating the need for pulleys or gear reducers.
- involute gear design to minimize noise.
- self-lubricating framix iron bearings.
- easy to maintain Buna-N lip seals, installed in the UniverSeal design for simple and quick replacements or change to an alternate shaft seal type.
- optional mounting brackets which are designed for in-line mounting with standard NEMA frame size motors.
- optional bearing and seal materials which allow effective operation up to 625F and 600PSI.
- simple field conversion on relief valve models to tank return mode.
- field reversible seal vent.
