Oilgear D-2025 Legacy Variable Displacement Pump is a series of two-way hydraulic pumps for applications that require smooth speed control, dependable pressure response, and long-term operational stability. The D-2025 has earned wide acceptance in heavy-duty industrial settings for its leading-edge reliability, precision, and efficiency in this framework. Its robust construction with a time-tested radial piston design enables it to perform consistently even under continuous operating conditions.

This variable displacement pump is designed to provide hydraulic power only in proportion to the work load. Due to the reduction of volumetric displacement depending on the demand condition of a system, the D-2025 greatly reduces energy loss and heat generation. Unlike fixed displacement systems that rely on throttling or excessive flow control, this pump responds instantly to resistance changes within the circuit. As a result, it improves system efficiency, minimizes unnecessary power consumption, and supports smoother machine operation.

The Oilgear D-2025 has a positive and variable delivery radially compact rolling piston mechanism that has the ability to work well at high pressures. The mechanism has the availability of one or two control mechanisms and also has high-pressure relief valves incorporated within it. The Oilgear D-2025 has a compact gear pump along with a relief valve and the Oilgear pintle check-type suction and return valve and hence has the ability to work in two-way differential and non-differential hydraulic systems.

In an open-loop hydraulic circuit system, the D-2025 exhibits unparalleled responsiveness with the use of electric hand servos or preset speed position controls. This makes the system very suitable for use in processing machines, metal forming machines, presses, as well as other automation systems. In addition to that, the system’s ability to cushion the reversals of flow helps to safeguard the system components.

Rexton Hydraulic serves industries through sales, repair, overhaul, or replacement for the Oilgear D-2025 Legacy Variable Displacement Pump. Experience matters when you want to ensure performance restoration and reliable hydraulic operation for existing oilgear displacement pump models that remain in service today.
