D Series Pump

Fixed Aluminum Gear Pump, 1.87-10.50 cc/rev Displacement.

The Aluminum Pump D Series fixed displacement gear pump offers high performance and high power density due to its aluminum construction, making it an ideal selection for the Aerial, Agriculture, Construction, Forestry, Material Handling, and Turf Equipment markets. It is available as a standard pump or a pump with a primary circuit relief valve.

A pressure-loaded gear pump consists of two, inter-meshing, hardened-steel, precision-ground gear assemblies. These precision gears are enclosed by a high-strength, die-cast aluminum front cover, back cover, and a high-yield, strength-extruded aluminum center section.
