Double Gear Pumps (DIU)

Haight offers eight sizes of oil gear 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.

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.
