The Oilgear D-20035 Legacy Variable Displacement Pump is a heavy-duty hydraulic pump catering to the requirements of applications where control of speed, pressure, and lifespan are crucial. This pump model relies on Oilgear’s successful D-Series range and finds many takers in processing machines, presses, extruder systems, and automated industrial operations requiring a controlled two-way flow.

This type of pump functions on a two-way, variable displacement system. The direction of the fluid or the output is directly controlled based upon the displacement. Consequently, the D-20035 caloric fluid circulating oil hydraulic piston pump generates a high degree of responsiveness in the system along with increased system efficiency and lower heat generation. The power consumption is directly proportional to the work done; hence it reduces the energy losses generated due to high throttling or pressure drop.

The Oilgear D-20035 comes with a strong radial rolling piston system that provides a consistent level of performance when operating under high pressure conditions. With a displacement capacity of around 528.97 cc/rev, it can handle high flow rates with pressure control. The built-in system can feature one or two control alternatives, high-pressure relief valves, a gear pump with a relief valve, along with pintle check-type suction/return valves for both two-way, differential, and non-differential systems designed by Oilgear.

With the capability of running at speeds of up to 900 RPM and withstanding continuous pressures of up to 4000 psi, the D-20035 is designed to serve the most demanding industrial application needs. The D-20035’s capability of eliminating external directional valves makes it convenient to use in hydraulic systems. Even though the company prefers the PVV series pumps for any kind of new application, the D-20035 remains the best choice for overhauling existing legacy systems.

Rexton Hydraulic is providing the following services: sales, repair, and replacement services for the Oilgear D-20035 Legacy Variable Displacement Pump, which is known as the High-Pressure Two-Way Hydraulic Pump.
