Product Description
Vickers PVB Series Axial Piston Variable Displacement Pump
Product Overview: The Eaton Vickers PVB series is a highly reliable axial piston variable pump engineered for Open Circuit industrial hydraulic systems. This series is a standard choice for machine tools, injection molding machinery, road rollers, and various compact power units. Known for its compact envelope, rapid response speeds, and exceptional power density, the PVB range is a benchmark in the hydraulic industry. Core models such as the PVB29-RS-20-C-11-PRC and PVB6-RSY-20-CV-11 offer precise pressure compensation, ensuring stable and efficient system operation.
Key Technical Advantages:
Precise Pressure Compensator Control (C/CV): Equipped with high-sensitivity compensators. Models like the PVB29-RS-20-C automatically modulate displacement based on system pressure, de-stroking once the set pressure is reached for significant energy savings.
Exceptional Volumetric Efficiency: Featuring precision-ground piston and cylinder block interfaces, the PVB series maintains minimal internal leakage even at high-pressure cycles of 21 MPa, ensuring smooth and powerful machine movements.
High Adaptability & Rotation Options: Available in RS (Right-hand/Clockwise) and LS (Left-hand/Counter-clockwise) configurations. The PVB6-RSY-20-CV-11 is optimized for tight spaces, making it ideal for integration into compact industrial power units.
Extended Service Life: Utilizing the classic Vickers Series 20 design, reinforced bearing systems and optimized porting plates effectively resist wear caused by hydraulic fluid contamination.
Specific Models & Technical Parameters:
Core Series: PVB5, PVB6, PVB10, PVB15, PVB20, PVB29, PVB45.
Detailed Config Codes: PVB29-RS-20-C-11-PRC, PVB6-RSY-20-CV-11.
