PV7-1X/40-45RE37MC0-16 Rexroth Vane Pump 160 Bar 45cc

Product Overview

The PV7-1X/40-45RE37MC0-16, PV7-11/06-14RA01MAO-10-A452, and PV7-11/06-14RA01MA0-10 represent the Bosch Rexroth PV7 Series of variable displacement vane pumps, spanning both pilot-operated and direct-controlled architectures. The PV7-1X/40-45RE37MC0-16 is a pilot-operated model with 45 cm³/rev displacement and 160 bar maximum operating pressure, engineered for medium-to-high pressure open-circuit industrial applications. The PV7-11/06-14 series are direct-controlled units with 14 cm³/rev displacement, 25.2 L/min maximum flow at 1450 rpm, and speeds up to 3000 rpm.

All three models feature mounting and connection dimensions compliant with VDMA 24560/1 and ISO 3019-2, enabling drop-in interchangeability. The cast iron housing and NBR seals ensure compatibility with HLP, HLPD, HVLP, and HVLPD hydraulic fluids. Every unit undergoes 100% simulated-condition testing before shipment.

Key Technical Advantages

1. Low Flow Pulsation with High Repetition Accuracy
PV7 Series variable vane pumps achieve exceptionally low flow pulsation across the full displacement range, thanks to their specific stator ring and vane cartridge design. Pressure peaks during down-control are effectively suppressed, delivering very high setpoint repeatability under fluctuating load conditions.

2. Hydrodynamically Lubricated Plain Bearings
The drive shaft is supported by hydrodynamically lubricated plain bearings. A dynamic pressure oil film forms within the bearing clearance during operation, achieving metal-free running. This design extends bearing service life and provides superior damping characteristics compared to rolling bearings.

3. Axial Compensation for Optimal Volumetric Efficiency
The displacer assembly incorporates axial gap compensation: as operating pressure rises, the end-face clearance is automatically minimized, reducing internal leakage to a minimum. This mechanism remains effective throughout the pump’s entire service life.

4. Modular Multiple Pump Combination
PV7 standard single pumps can be combined with internal gear pumps, axial piston pumps, or radial piston pumps via the through-drive shaft, forming multiple pump systems without additional couplings or mounting brackets — simplifying circuit design for multi-loop hydraulic systems.

Application Areas

• Machine Tool Hydraulic Power Units: CNC hydraulic stations requiring precise pressure control and low-noise operation

• Plastic Injection Molding: Variable-flow circuits for clamping and injection units

• Metallurgical Auxiliary Hydraulics: Rolling mill and continuous casting auxiliary systems

• Marine Hydraulic Systems: Medium-pressure power sources for winches and windlasses

• General Industrial Hydraulic Power Units: Open-circuit variable-flow systems up to 160 bar, particularly for applications requiring frequent pressure switching

Expert Maintenance Tips

1. Zero-Stroke Pressure Verification and Calibration: PV7 pumps are factory-calibrated for optimal operating noise at the specified zero-stroke pressure. If actual conditions require a different setting, recalibrate using the adjustment screw after the system reaches operating temperature, and verify noise levels remain within acceptable limits.

2. Pilot Circuit Cleanliness: The PV7-1X/40-45RE37MC0-16 uses a pilot control spool sensitive to contamination. Maintain fluid cleanliness at ISO 4406 18/16/13 or better. Particulate contamination can cause sluggish or oscillating control response.

3. Through-Drive Protection: When the through-drive is not in use, the aluminum protective cover on the rear cover must remain installed to prevent dust and moisture ingress. Remove only in a clean environment when adding a combination pump.

4. Case Drain Configuration: Ensure the case drain line is unobstructed and return back-pressure remains within limits. Excessive back-pressure causes shaft seal failure and abnormal housing temperature rise. For PV7-11/06-14 direct-controlled models, route the drain line independently to the reservoir.
