Features:
- Reduce maintenance expenses - simple, quick seal changes
- Less production disruption and downtime - perform maintenance in place rather than in the shop
- Reduce maintenance inventory - one pump can be adapted to meet many application requirements
- Provide future adaptability - easily change the pump as your needs change
- Reduce replacement parts costs, no special custom design parts
- Interchangeable with existing Haight pumps without modification
- Pumps specified with an integral relief valve can be quickly and easily changed to perform in either suction return, or tank return mode. The relief valve can be readily changed to operate in either clockwise or counterclockwise flow direction.
The Universal Pump Design combines the innovation of UniverSeal shaft seal, the rugged simplicity of Haight's proven "gear within a gear" internal gear configuration, with the flexibility of a bolt-on, integral Relief Valve assembly. This combination of pump features offers pump users unsurpassed flexibility to adapt their pumps to changing system requirements.
Universal Relief Valve - the relief valve assembly can be added at any time, in the field, with no special tools. The valve can function in either the return to suction mode, or return to tank mode.
Gear within a gear" Internal gear design - For nearly seventy years, this design has demonstrated it's effectiveness in handling a broad range of applications while operating at standard motor speeds, and reducing wear. Both of these operating characteristics play an important role in minimizing overall capital investment, and operating expenses.
UniverSeal shaft seal configuration represents a significant advance in gear pump design.
