Oilgear PVWH-45 Axial Piston Hydraulic Pump is a fixed-displacement axial-piston pump from the legacy PVWH series. With a displacement of 98 cc/rev, this pump gives you considerable hydraulic flow per revolution. This makes PVWH-45 ready for duty where your hydraulic system requires generous flow, reliable pressure handling, and a robust but compact pump design that best fits medium-duty to heavy hydraulic circuits.

PVWH-45 operates in an open-loop circuit, giving you simplicity and flexibility in hydraulic system design. It supports a maximum continuous operating pressure of 172 bar and a maximum shaft speed of 2700 RPM. This rating ensures stable, dependable performance under regular loads and allows the pump to deliver steady output across a wide range of operating conditions.

Thanks to the 98 cc/rev displacement provided, along with each shaft turn, the pump supplies a strong volume of hydraulic fluid. Further, that makes it suitable for applications requiring sustained flow: hydraulic presses, power packs, medium-size mobile equipment, and industrial machines needing continuous hydraulic delivery without spikes or pressure drops. The fixed-displacement construction ensures predictable, repeatable output-valuable for systems where stability in flow and pressure takes preference over variable output.

Internally, PVWH-45 shares all the proven qualities of the PVWH series. It features rugged construction, hardened internal surfaces, and a design optimized for long life and reliability - even when used with modern hydraulic fluids including lower-viscosity or low-lubricity oils. This fluid compatibility adds flexibility for different industrial environments and helps reduce maintenance demands.

The pump's size and configuration allow easy installation in a variety of hydraulic layouts. Its robust build supports continuous duty cycles and steady performance, making it a good fit for industrial presses, hydraulic power units, mobile machinery, material-handling hydraulics, and auxiliary circuits — wherever reliable flow and steady performance are required without the complexity of variable-displacement systems.
