Oilgear PVWH-25 Axial Piston Hydraulic Pump is a fixed-displacement axial-piston pump designed for hydraulic systems that need strong flow output, dependable performance, and easy integration. With a displacement of 64 cc/rev, this pump is one of the larger models in the PVWH legacy line, offering substantial hydraulic volume per revolution.
PVWH-25 is designed for open-loop circuits. This simplifies hydraulic design and control. The maximum continuous pressure is supported at 345 bar for this pump, ensuring reliability under sustained loads or demanding conditions. The maximum operating speed is 2700 RPM. This allows flow delivery with due consideration given to mechanical stability and service life.
The internal construction of PVWH-25 focuses on robustness and fluid versatility. Like all pumps of the PVWH series, it runs modern hydraulic fluids, including those with low viscosity or low lubricity, which enables this pump to adapt to variable industrial settings easily. Hardened pistons, precision machining, and the balanced rotating parts minimize wear and ensure high reliability for long time periods under operation. The pump design is also sealed to reduce the need for maintenance, making it practical for systems where uptime is considered important.
By its principle of fixed-displacement, the PVWH-25 gives consistent, repeatable flow every time the shaft turns. This predictability is useful in applications requiring steady hydraulic supply, such as compact hydraulic power units, auxiliary circuits, presses, actuators, clamping systems, or mobile equipment with medium hydraulic demand. The relatively high displacement, combined with its manageable size, makes it a flexible middle-ground pump: more capacity than small auxiliary pumps, but simpler than large heavy-duty units.
Its installation footprint and configuration remain compact enough for tight machinery spaces. Engineers can mount PVWH-25 in systems where space, cost, and reliability all matter. For clients needing a dependable, efficient, and straightforward hydraulic pump, PVWH-25 offers an excellent balance of output, pressure, and simplicity.
