Oilgear Type D Variable Displacement Pumps are of the radial rolling piston and pintle type for pressures up to 3000 PSI.

D Pump systems are providing unexcelled speed control on processing machines. This pump is able to respond instantly to conveniently located electric hand servos or preset speed position controls.

With Oilgear Variable Displacement Pumps, power is only used in proportion to the work performed. The Volumetric displacement is selected to suit and the pressure responds instantly to the resistance met. No power is wasted in the form of heat through chokes, orifices, or excessive piping.
