Oilgear PVWH-34 Axial Piston Hydraulic Pump

Oilgear PVWH-34 Axial Piston Hydraulic Pump is a fixed-displacement axial-piston pump that was part of the legacy PVWH series, with a displacement of 76 cc/rev. This offers an excellent balance between substantial flow capacity and compact size, thus making the pump particularly effective in medium-duty to moderately heavy hydraulic applications that require reliable flow.

The PVWH-34 is designed for open-loop hydraulic circuits and provides reliable performance even with low-lubricity or modern hydraulic fluids. It is, therefore, ideal in industries where compatibility with a fluid and ease of service are primary factors.

The pump supports a maximum continuous pressure of 242 bar - enough for a wide range of industrial and mobile hydro-mechanical operations. The maximum rated shaft speed is 2700 RPM to ensure that fluid delivery remains steady under varying load conditions and cyclical demands.

Because of its 76 cc/rev displacement, PVWH-34 can provide substantial flow per revolution. This makes it a good fit for hydraulic systems that have moderate-to-high flow rates and do not require over-sized hardware. Its fixed-displacement nature means that with every shaft turn, predictable, repeatable output is achieved-a benefit in systems where consistency and reliability are priorities.

Internal construction features Oilgear’s proven design: hardened internal surfaces, robust piston/swashplate geometry, and robust valve/port design ensure minimum internal wear, good resistance against contamination, and greater longevity. Its compatibility with low-viscosity fluid extends the pump’s use across the spectrum of industrial fluids, giving flexibility in system design.

The compact size of the PVWH-34 allows for its easy integration in machines where space is a key concern, whether it be for new installations or retrofits. This series applies to medium-duty presses, hydraulic power packs, auxiliary circuits for mobile and industrial machinery, hydraulics for material-handling applications, and systems demanding reliable flow with reasonable pressures.
