Product Overview
The ANSON PVF-40-55-11S is a high-performance variable displacement vane pump engineered for industrial hydraulic systems requiring precise flow control and energy-efficient operation. Manufactured by ANSON, a recognized name in hydraulic component design, this pump utilizes a pressure-compensated variable displacement vane mechanism in which an internal cam ring shifts eccentrically relative to the rotor in response to system pressure. This design allows the pump to automatically reduce output flow as system demand decreases, minimizing heat generation and power consumption. The PVF-40-55-11S is a direct-fit replacement for original equipment and is widely deployed in continuous-duty industrial circuits where stable flow, low noise, and long service life are critical.

Engineering Features & Advantages
- Precision Performance: The variable displacement vane mechanism with pressure compensation delivers only the flow required by the circuit, reducing throttling losses, heat buildup, and overall energy consumption compared to fixed displacement pumps.
- Low Noise Operation: Precision-ground vanes and a dynamically balanced rotor within the cam ring minimize pressure pulsation and hydraulic noise, making the PVF-40-55-11S suitable for noise-sensitive industrial environments.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened cam ring and vane contact surfaces that resist wear and maintain volumetric efficiency over extended service intervals.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, allowing drop-in replacement without modification to mounting flanges, shaft couplings, or port connections.
Typical Industrial Applications
The ANSON PVF-40-55-11S is commonly specified in plastic injection molding machines, metallurgical presses, CNC machine tools, and general industrial power units where variable flow and pressure-compensated control are required. It is also well suited to construction and marine hydraulic systems, hydraulic power packs, and automated manufacturing lines demanding stable, low-noise vane pump performance with reliable continuous-duty operation.
