Rexroth Type 1PV2V Series Variable Vane Pump | 1PV2V4-17/20, 1PV2V3-42/25

1PV2V Series High-Precision Pilot-Operated Variable Vane Pumps

Product Overview: The 1PV2V Series is the premier industrial solution for achieving “Extreme Pressure Control Precision” and “System Energy Optimization.” As a pilot-operated variable displacement vane pump, it utilizes an integrated pilot valve to sensitively compensate output pressure and flow, significantly reducing overflow losses and system temperature rise. This range features core models including 1PV2V4-17/20RE01MD160A0 and 1PV2V3-42/25RG01MC100A0. With its compact cartridge-style design and rapid dynamic response, the 1PV2V series is the ideal choice for CNC machine tool clamping circuits, plastic processing machinery, and various medium-pressure energy-saving power units.

Key Technical Advantages:

• Precision Pilot Pressure Compensation: The pilot-operated structure offers smaller pressure override and faster response times compared to direct-acting pumps, ensuring smooth actuator movement.

• Exceptional Energy Efficiency: Once the system reaches the preset pressure (e.g., in pressure-holding states), the displacement automatically drops to a minimum, significantly cutting motor load.

• Peak Silent Operation: Optimized internal flow paths and rotor-vane assemblies ensure exceptionally low noise levels during both full-load operation and zero-flow holding phases.

• High Reliability & Long Service Life: Radial hydraulic load balancing technology minimizes bearing wear, maintaining long-term stability even under frequent pressure switching cycles.

• Target Applications: Precision CNC machine tools, die-casting auxiliary circuits, automated assembly lines, woodworking machinery, and compact hydraulic power units.
