Product Description

Product Overview:

The R900598753 PV7-1X/10-14RE01MC3-16, R900593330 PV7-1X/40-45RE37MD0-16 and PV7 series are Bosch Rexroth pilot-operated variable displacement vane pumps. These units enable precise pressure and flow control via pilot operation, delivering low noise, low pulsation and fast response. Manufactured to exact original geometric tolerances, they offer true drop-in interchangeability—matching mounting flanges, shaft ends and port centers precisely—so they can replace OEM units without system modifications. Every pump undergoes 100% simulated duty-cycle testing to verify volumetric efficiency, pressure retention and control accuracy. Hydraulic balancing of the vanes combined with precision-machined cam rings and rotors ensures long service life, making them ideal for machine tools, constant-pressure systems and precision hydraulic equipment.

Technical Specifications

Key Technical Advantages:

True drop-in interchangeability and precision machining: Exact match to Rexroth original mounting dimensions, shaft ends and port centers enables direct OEM replacement without system changes, minimizing downtime and modification costs. High-precision cam ring, rotor and vane processing ensures consistent performance.
High volumetric efficiency with hydraulic balancing: Pressure-balanced vanes significantly reduce cam-ring wear, delivering high volumetric efficiency and low zero-stroke leakage, ideal for energy-efficient constant-pressure systems.
Low-noise and low-pulsation design: Optimized inlet geometry and vane configuration minimize oil turbulence and flow ripple, resulting in quiet operation suitable for noise-sensitive precision machine-tool environments.
Fast response and long-life bearings: Pilot control provides extremely short up/down stroke times and low hysteresis; hydrodynamically lubricated plain bearings extend service life and simplify field maintenance.

Application Areas:

Constant-pressure hydraulic systems for machine tools and machining centers, hydrostatic bearing lubrication, injection-molding and die-casting auxiliary circuits, precision hydraulic test stands, industrial automation equipment and any fixed installation requiring accurate pressure/flow control.

Expert Maintenance Tips:

Ensure precise shaft alignment during installation (flexible coupling recommended); radial and axial forces must not be applied to the shaft.
Fully prime the pump and verify a leak-free, air-free suction line before initial start-up; use HLP mineral oil (DIN 51524) with cleanliness class ISO 4406 19/16/13 or better.
Maintain suction and return filters regularly to prevent particle ingress that can score vanes and the cam ring; keep operating oil temperature between –10 and +70°C and viscosity 16–160 mm²/s.
Adjust pressure/flow screws according to original instructions; for long-term storage, run the pump briefly every 3–6 months to prevent internal corrosion.
