Rexroth Type 1PV Series Pilot Variable Vane Pump | 1PV2V4-20, 1PV2V3-40 | 16MPa

Rexroth Type 1PV Series Pilot-Operated Variable Displacement Vane Pumps

Product Overview: The 1PV Series is a high-performance Pilot Operated Variable Vane Pump engineered for industrial hydraulic systems requiring precise pressure regulation and high-efficiency output. Compared to standard direct-acting pumps, the pilot control mechanism ensures a smoother transition during pressure compensation and exceptional repeatability. This page features the core specifications: 1PV2V4-20/20RA01MC1-16A1 and 1PV2V3-30/40RA01MC63A1. With its precision-ground port plates, the 1PV series maintains superior volumetric efficiency and minimizes system heat generation even at continuous operating pressures up to 16.0 MPa (160 Bar).

Key Technical Advantages:

• Precision Pilot Control: The integrated pilot pressure regulator provides narrow pressure cut-off hysteresis, ensuring actuator precision at critical pressure limits.

• Exceptional Energy Efficiency: Delivers “Oil on Demand.” When the system reaches the preset pressure, displacement automatically reduces to a compensation state, eliminating the energy waste typical of relief valves.

• High-Pressure Durability: The 1PV2V4 series supports rated pressures up to 16.0 MPa, significantly higher than the 7.0 MPa limit of conventional variable vane pumps.

• Low Noise & Extended Life: Utilizing a hydrostatically balanced structure, the pump suppresses pressure pulsations, effectively extending the service life of bearings and internal cartridges.

• Target Applications: Precision machine tools, automated production lines, hydraulic clamping systems, test benches, and energy-saving Hydraulic Power Units (HPU).
