DOUBLE GEAR PUMPS

Gear Pumps

Haight offers five sizes of pumps in the Double Pump Series. Available with a variety of optional seal, bearing and rotor materials. The Double Pump Series offers exceptionally compact design, plus low shear and noise characteristics.

Compact, rugged and simple, these pumps are ideally suited for close-couple mounting, which eliminates the need for expensive gear boxes, and prevents coupling alignment problems. (44-80 gpm)

FEATURES

Operation at standard motor speeds, eliminating the need for pulleys and gear reducers.
Involute gear design to reduce noise.
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.
Close-coupled mounting to eliminate motor and pump difficulty.
300# ANSI flange and NPT inlet/outlet connection.
Reversible flow, plus field convertible seal venting.
Ductile 65 construction.

The Universal Pump Design (series DIU) combines the innovation of our 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. Available with three different tension springs, the relief valve operates smoothly and effectively over a broad range of setting values.

"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.

The UniverSeal shaft seal configuration represents a significant advance in gear pump design. The UniverSeal incorporates standard, easily available seal components with a readily adaptable pump geometry. The pump can be easily converted in the field from Lip to Mechanical to Packed Gland shaft seal type without even disconnecting the piping. Flow direction in the pump can also be changed without disrupting the attached piping, or special tools.

ALL UNIVERSEAL SHAFT SEAL PUMPS FEATURE....

reduced maintenance expenses - simple, quick seal changes
less production disruption and downtime - perform maintenance in place rather than in the shop
reduced maintenance inventory - one pump can be adapted to meet many application requirements
future adaptability - easily change the pump as your needs change
reduced 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.
