Oilgear PVM-025 Variable Displacement Hydraulic Pump

Oilgear PVM-025 Variable Displacement Hydraulic Pump is a versatile variable-displacement axial piston pump designed for open-loop hydraulic systems where high precision and performance are called for. This pump provides controlled hydraulic flow up to 25 cc/rev for light and medium-duty industrial and mobile applications that demand reliability in performance with efficient energy use.

Given that it is designed for flexibility in operation along with much stability, the PVM-025 can support a maximum continuous pressure of 260 bar, approximately 3750 psi, at speeds up to 2700 RPM. In real-world hydraulic conditions, if it runs around 1800 RPM at the rated continuous pressure under normal inlet conditions, the produced fluid flow is about 38.2 L/min ≈ 10.1 gpm.

It is a variable displacement design that allows for the operator to command output flow based upon system demand. Unlike other fixed-displacement pumps, PVM-025 pumps only deliver the amount of flow called for at a particular moment, thereby reducing wasted energy and heat buildup. This makes this type of pump suitable for applications like compact hydraulic presses, auxiliary circuits, cylinder actuation, mobile machine hydraulics, and auxiliary power units given the need to adapt to ever-changing load conditions.

Oilgear's engineering for the PVM series emphasizes durability, long service life. Rotating group and piston assembly are precisely machined and balanced for smooth operation. With hardened internal surfaces, this minimizes wear and extends resistance to contamination — even when handling modern low-lubricity hydraulic fluids.

Due to its modular construction, the PVM-025 has compact dimensions and easily fits into diverse hydraulic layouts. Whether applied to standalone machines or complex hydraulic power units, it is an assurance of excellent performance in keeping the system functional.

At Rexton Hydraulic, we offer sales, installation, and servicing the full series of the PVM pump, such as the PVM-025. The choice of model, installation, and maintenance are fully supported to ensure that hydraulic systems perform stably and reliably during their service life.
