PV7-16/16-20RE01MC0-16 Rexroth Variable Vane Pump 20cc 160bar

Product Overview

The PV7 series (including PV7-16/16-20RE01MC0-16, PV7-18, PV7-1A, PV7-2A and PV7-1X) are Bosch Rexroth pilot-operated variable displacement vane pumps. Designed for adjustable pressure and flow with low noise, low hysteresis, fast response and long service life, they are ideal for constant-pressure systems and precision control circuits. We specialize in the R&D and manufacturing of high-pressure pumps, motors and valve blocks. Our products offer 100% drop-in interchangeability with genuine Rexroth PV7 units and undergo 100% simulated operating-condition testing. Precision machining and high-quality materials ensure stable adjustable flow under industrial high-pressure conditions for machine tools, hydrostatic bearings and constant-pressure hydraulic systems.

Key Technical Advantages

1. Pilot control and low hysteresis design: Precise pressure and flow control with short on/off-stroke times and high repeatability, ideal for precision constant-pressure systems.
2. Low-noise and long-life bearings: Hydrodynamically lubricated plain bearings significantly reduce noise and wear for smooth, quiet operation.
3. Flexible adjustment and combination capability: Maximum displacement adjustable; supports multiple pump combinations for complex hydraulic circuits.
4. 100% drop-in interchangeability and simulated-condition testing: Overall dimensions, mounting interfaces and control characteristics match genuine Rexroth units exactly for direct replacement. Every unit undergoes 100% simulated operating-condition testing to verify pressure, flow, efficiency and sealing performance.
5. High-reliability industrial design: Cast-iron housing suitable for demanding environments such as machine tools and hydrostatic systems.

Application Areas

• Machine tools and machining centers: main hydraulic systems, clamping and feed
• Hydrostatic bearing systems: constant-pressure oil supply
• Constant-pressure hydraulic power units: industrial equipment power source
• Precision machinery requiring low-noise, high-accuracy variable control

Expert Maintenance Tips

• Before installation, confirm rotation and flange match the host machine. Ensure adequate suction line diameter and proper sealing; maintain inlet pressure at 0.8–2.5 bar.
• Use HLP mineral oil according to DIN 51524 with cleanliness ISO 4406 19/16/13 or better; run at low speed during cold starts.
• Regularly check the pressure adjusting screw and pilot control circuit to keep settings stable; avoid prolonged over-pressure operation.
• When replacing seals or internal components, maintain strict cleanliness; perform air bleeding and low-pressure test run after assembly.
• Perform preventive inspections every 2000–4000 hours depending on duty cycle; monitor noise, temperature and leakage changes, and service promptly.
