Oilgear PVWH-20 Axial Piston Hydraulic Pump is a tough, fixed-displacement pump designed for medium-duty hydraulic systems where dependable flow output, stable pressure performance, and long-term reliability are key. With its displacement of 46 cc/rev, this model ensures a potent hydraulic output, making it suitable for a wide range of industrial and mobile applications where consistent performance is crucial.
The PVWH-20 is designed for open-loop circuits and makes the process of system integration simple and easy with its smooth, predictable hydraulic behavior. It has a maximum continuous operating pressure of 172 bar, thus performing reliably in applications that have moderate loads and run for long periods. It also supports speeds up to 2700 RPM, making it responsive and adaptive to variable duty cycles or intermittent flow demand found in some equipment.
The internal engineering of the PVWH-20 concentrates on durability, mechanical stability, and efficiency of operation. Oilgear uses hardened wear surfaces, precision-machined pistons, and a well-balanced rotating group to minimize friction inside the pump and thus provide smooth pumping action. These features contribute to an extended service life, reduced operating noise, and consistently high performance even during long operating periods. It also provides a flow of about 13.3 gallons per minute at rated speed and pressure, giving ample capacity for most medium-duty hydraulic systems.
Among the major advantages of the PVWH series is fluid compatibility. The PVWH-20 works reliably with the broadest range of modern hydraulic fluids, including low-lubricity options and environmentally friendly formulations. This makes it suitable for advanced or specialized hydraulic media usage inside systems without compromising pump performance or longevity.
With its compact frame and practical mounting configuration, the PVWH-20 fits easily into both new hydraulic builds and retrofit applications. Due to a fixed-displacement design, consistent and repeatable flow is ensured, and thus this hydraulic pump is ideal for presses, material-handling equipment, mobile machinery, auxiliary circuits, compact power units, and other industrial machines that operate best under a steady hydraulic supply.
