1PV2V4-27/80RA01MC100A1 Rexroth Variable Vane Pump 82.8cc 160bar

Product Overview

The 1PV / 1PV2 / 1PV2V / 1PV2V3 / 1PV2V4 series are Bosch Rexroth variable-displacement vane pumps designed for industrial hydraulic systems with pressure-compensated control. These units are precision direct interchanges for original Rexroth 1PV2V4 models including 1PV2V4-27/80RA01MC100A1. Featuring hydraulically balanced vanes and precision-machined cartridges, they deliver high volumetric efficiency and low noise. Every pump undergoes 100% simulated duty-cycle testing to guarantee exact match of mounting flanges, shaft ends, port locations and performance curves.

Key Technical Advantages

1. Pressure-compensated variable control: Automatically adjusts displacement according to system pressure for energy savings and reduced heat generation.
2. Hydraulically balanced vanes and precision cartridge: Minimize wear, deliver high volumetric efficiency and low internal leakage.
3. Precision machining for true interchangeability: Matches original Rexroth mounting dimensions, shaft ends and port orientations exactly—direct drop-in replacement.
4. Low noise and long-life bearings: Optimized flow paths reduce ripple; quality bearings support continuous industrial duty.
5. 100% simulated operating-condition testing: Full pressure, flow, leakage and noise verification ensures consistency with OEM performance curves.

Application Areas

Injection molding machines, die-casting machines, machine-tool hydraulic systems, presses, steel and metallurgical equipment, port machinery, industrial power units and medium-pressure systems requiring variable displacement for energy efficiency.

Expert Maintenance Tips

Ensure precise shaft alignment; radial or axial loads are not permitted. Maintain inlet pressure between 0.8 and 2.5 bar to prevent cavitation. Use HLP mineral oil to DIN 51524 (viscosity 16–160 mm²/s); target system cleanliness of ISO 18/16/13 or better. Fully bleed air before initial start-up and monitor temperature and leakage during break-in. Regularly check compensator settings and shaft seals; never allow dry running.
