Oilgear PVWJ Series Pump | PVWJ-011, PVWJ-022, PVWJ-098 | 250 Bar Variable Piston Pump

Oilgear PVWJ Series Compact Variable Axial Piston Pump

Product Overview: The Oilgear PVWJ series is a globally recognized benchmark for efficiency and compact engineering in hydraulic systems. Spanning displacements from the ultra-portable 11cc (PVWJ-011) to the high-capacity 98cc (PVWJ-098), the PVWJ pumps utilize Oilgear’s signature hydrostatic balancing technology and hardened steel valve plates. These features ensure exceptional durability under a rated pressure of 250 Bar (3625 PSI). Thanks to its unique material composition, the PVWJ series maintains stable performance even when handling low-viscosity fluids or specialized synthetic media, making it the premier choice for applications with restricted installation footprints.

Key Technical Advantages:

• Extremely Compact Architecture: Specifically engineered for space-constrained equipment, delivering robust pressure output within a miniaturized frame to streamline compact hydraulic power unit (HPU) layouts.

• Hardened Steel Valve Plate: Compared to conventional soft materials, hardened steel significantly enhances wear resistance, providing an extended service life during continuous, high-frequency duty cycles.

• Versatile Intelligent Controls (RSAY/LDES):

  • RSAY Pressure Compensation: Models like the PVWJ-011-A1UV-RSAY automatically adjust flow when target pressure is reached, optimizing energy consumption.

  • LDES Electronic Control: Models like the PVWJ-098-A1UV LDES support advanced proportional displacement modulation, perfect for complex automated logic systems.

• Superior Suction & Response Speeds: Optimized inlet porting ensures excellent fluid charging at high speeds with rapid response times, effortlessly handling instantaneous system load variations.

• Universal Fluid Compatibility: Rugged internal components allow stable operation not only with standard hydraulic oils but also with specialized fluids such as water-glycol.
