Overview
The Oilgear PVWH011A13VLGBSP1NNSNNN is a variable-displacement, open-loop axial-piston hydraulic pump built for demanding industrial and mobile applications. This legacy series pump delivers consistent pressure and capacity control with a robust design that performs exceptionally well on low-viscosity fluids, including fire-resistant and environmentally friendly formulations. The pump’s modular configuration and flexible displacement options make it a versatile solution for hydraulic systems requiring medium-duty performance and long operational life.
Key Features
- Open-loop, variable-displacement design for efficient pressure and capacity matching
- Polymerous journal bearings enable operation on low-viscosity and special fluids with extended bearing life
- Hardened cylinder barrel and valve plate surfaces resist contamination and wear
- Pressure-lubricated swashblock design ensures high performance and durability
- Multiple frame sizes and displacement ranges provide flexible system integration
- Field-proven reliability across industrial, mobile, and hydraulic systems
Technical Specifications
While exact displacement and performance ratings are subject to configuration-specific data, the PVWH011A series is engineered to deliver:
- Pump Type: Open-loop, variable-displacement, axial-piston pump
- Series: PVWH (011 frame size)
- Displacement: Configuration-dependent; consult factory for exact cc/rev
- Pressure Rating: Consult Oilgear technical data for pressure curve specifications
- Speed Range: Standard and higher speeds available—contact Oilgear for operating envelope
- Fluid Compatibility: Optimized for low-viscosity ISO fluids, water-based fluids, and fire-resistant formulations (Skydrol®, Stack Magic®, Erifon®, 98/2)
- Control Options: Available with various pressure compensators and load-sense controls
- Case Drain Requirement: Low-pressure external drain required
