The Oilgear PVWJ-025 Variable Displacement Axial Piston Pump is designed for hydraulic systems that need a compact, reliable and cost-effective variable displacement solution. With a displacement of 25 cc/rev this pump offers balanced hydraulic power for many smalls to medium hydraulic equipment with limited space. These pumps are Ideal for light to medium mobile machines, small industrial presses auxiliary hydraulic systems and others.

This pump operates up to 345 bar continuous operating pressure and 3,000 RPM maximum shaft speed. This makes it capable of handling demanding cycles and stable output even under variable load conditions. The PVWJ-025 is open loop hydraulic circuit pump, delivering fluid flow and pressure for various applications.

Oilgear PVWJ series is known for durability, flexibility and low maintenance. The rotating group and swash block are designed with robust surfaces, polymer-based bearings and sealed front shaft bearing arrangement. The internal structure increases resistance to contamination, allows use of low viscosity or special hydraulic fluids and long life.

PVWJ-025 comes with medium control response that makes it suitable for applications where high flow and pressure required. The displacement can be adjusted according to system demand, providing smooth hydraulic operation for tasks like hoisting, clamping, steering or auxiliary fluid circuits.

This pump offers Installation flexibility which is another advantage. The PVWJ-025 has multiple porting options (top/bottom or rear), various shaft configurations and rotation directions and different sealing and mounting options. This makes it easy to integrate into existing or new equipment.

Overall Oilgear PVWJ-025 Variable Displacement Axial Piston Pump is a robust pump comes in compact size, perfect of limited space condition. This is also known for performance and reliability. It’s suitable for light to medium duty mobile or industrial applications and systems that requires low maintenance and fluid flexibility.
