Oilgear PVWW-130 Variable Displacement Hydraulic Pump

Oilgear PVWW-130 Variable Displacement Axial Piston Hydraulic Pump is designed for open-loop hydraulic systems requiring reliable performance in hydraulic and low-lubricity fluids. As part of Oilgear's PVWW Series, this pump was developed specially for applications with high water-content fluids, which most conventional hydraulic pumps often face lubrication and wear challenges. Its rugged construction and stable control characteristics make it a fitting solution for demanding industrial hydraulic systems.

With a maximum theoretical displacement of 130.2 ml/rev, the PVWW-130 delivers high volumetric output with controlled and responsive flow regulation. The variable displacement design allows the pump to automatically adjust output based on system demand, improving energy efficiency, minimizing heat generation, and ensuring smooth system performance against changing load conditions. These features make it particularly valuable in applications with fluctuating operational requirements.

The pump is rated to operate continuously at a pressure of 82.7 bar and can withstand a peak pressure of 103.4 bar, affording stable operation during continuous running and short-duration pressure spikes. Operating at a maximum speed of 1800 RPM, the PVWW-130 offers a robust flow of 56.5 gpm against rated continuous pressure, with standard inlet conditions. This sits well with higher-capacity hydraulic circuits that need consistent and reliable flow delivery.

The PVWW-130 is based on a Frame Size C housing, with SAE "C" 2-bolt face mounting for easy installation, and thus compatibility with a wide range of hydraulic power units and industrial machinery. With a weight of 46.8 kg, the pump reflects robust internal construction designed for long-term durability. Flexible top, bottom, and rear port locations further simplify system integration and layout planning.

Typical applications of Oilgear PVWW-130 include general industrial machinery, hydraulic power units, material handling systems, steel and metal processing equipment, and hydraulic systems using high water-content or environmentally sensitive fluids.
