Rexroth 1PV2V4-27 Variable Vane Pump | 1PV2V3 1PV2V5 | 1PV2V4-2X Series

LIC Hydraulic offers the Rexroth 1PV2V Series, a direct-operated variable displacement vane pump designed for high-efficiency industrial applications. By utilizing an integrated pressure compensator, the 1PV2V4-27 automatically reduces flow to the minimum required to maintain system pressure, effectively eliminating energy waste through relief valves. With its compact footprint and quiet operation, it remains the preferred choice for machine tool builders and industrial HPU manufacturers globally.

Key Technical Features

• Energy Efficiency: The pressure-compensated stroke control reduces power consumption during idling phases, significantly lowering oil temperature and extending seal life.

• Quiet Operation: Precision-ground vane tracks and balanced internal forces ensure smooth fluid delivery with minimal vibration.

• Adjustable Pressure Settings: The MC100 compensator allows users to fine-tune the cut-off pressure to match specific application requirements.

• Proven Reliability: Built on Rexroth’s decades of vane pump expertise, the 1PV2V series is engineered for high duty cycles in factory environments.

Expert Maintenance Tips

• Air Bleeding: During the initial startup, ensure all air is bled from the pump housing through the case drain port to prevent vane damage.

• Oil Cleanliness: Maintain a filtration level of ISO 4406 18/16/13. Variable vane pumps are sensitive to fine particles which can cause the compensator piston to stick.

• Case Drain Line: Always ensure the case drain line is connected directly to the reservoir with minimal backpressure. High case pressure will blow the shaft seal.
