Oilgear PVL-320 Axial Piston Hydraulic Pump is specifically designed for heavy-duty open-loop hydraulic systems needing continuous high-pressure capability with strong fluid delivery. A member of the proven PVL Series from Oilgear, this pump features a modular design that simplifies maintenance and allows reliable operation under demanding industrial loads. Featuring a two-way delivery mechanism, sturdy construction makes it apt for systems needing strength and serviceability.

The model PVL-320 is designed for operation at continuous pressures to 5000 psi, providing a very high flow capacity while maintaining efficient and stable pressure performance. With a large displacement of 562.07 cc/rev, this model has substantial hydraulic throughput, making it an excellent choice for high-capacity circuits where strong fluid power is necessary without sacrificing system responsiveness.

Operating at a standard drive speed and 5000 psi, PVL-320 is capable of generating a powerful 122 gpm of flow. Most high-flow applications can be satisfied by this output, ranging from big presses and forming devices to injection molding machines to all other industrial installations needing fast, controlled motion under load. For short-term surges and heavy-duty cycles, the pump is also rated for peak pressures up to 6500 psi, providing an additional margin of safety in periods of violent load variations.

The PVL-320, with a maximum operating speed of 1200 RPM, is specifically designed for high-pressure applications while considerably limiting internal wear and heat generation. The open-loop configuration makes this series easy to integrate and operate reliably within existing hydraulic systems. The modular construction of the pump means less downtime due to maintenance or configuration changes.

Oilgear PVL-320 commonly used in high-pressure industrial power units, large hydraulic press systems, metal working machinery, steel mill hydraulics and other heavy industrial equipment where sustainable and reliable performance is paramount. Rexton Hydraulic offers the Oilgear PVL-320 Axial Piston Hydraulic Pump within their entire range and models.
