Oilgear PVM-065 Variable Displacement Hydraulic Pump

Oilgear PVM-065 Variable Displacement Hydraulic Pump is a high-performance variable-displacement axial-piston pump from the legacy series of Oilgear. Designed for open-loop hydraulic systems, this pump offers a strong blend of adjustable flow, robust pressure capability, and smooth hydraulic control. These are ideal for medium- to heavy-duty applications where responsiveness and efficiency are essential.

With its max displacement of 65 cc/rev, PVM-065 gives enough fluid movement per shaft revolution, which allows it to do the job of high hydraulic power without overweighting your system. This mid-to-higher displacement makes it well suited for driving medium-sized cylinders, hydraulic presses, actuator circuits, power units, and mobile equipment hydraulics.

This pump is compatible with a steady-state operating pressure of up to 260 bar, making it highly suitable for heavy-duty applications while keeping flow and pressure characteristics stable. This rating of pressure will keep the PVM-065 running reliably in an industrial environment when performance under load is critical.

The PVM-065 is rated at a maximum speed of about 2700 RPM. In normal rated conditions-such as 1800 RPM and continuous pressure-it produces about 105.6 litres per minute (≈ 27.9 gallons per minute) of hydraulic flow. This output level ensures high midrange flow for systems needing responsive behavior without sacrificing precision or power.

Variable-displacement technology gives PVM-065 an edge in performance. Unlike fixed displacement pumps that always deliver the same flow, the output of a variable displacement pump varies with system demand. As such, this technology optimizes energy utilization, minimizes heat generation, and increases control accuracy, hence enhancing system performance and reducing operating costs.

The internal design emphasizes durability and fluid flexibility. Featuring hardened pistons, precision-machined components, and a balanced swashplate system, the PVM-065 operates very smoothly, with increased resistance to wear. It also works effectively with modern hydraulic fluids, including low-lubricity and specialty oils, increasing versatility across industrial and mobile applications.
