PVQ40-B2R-SE1F-10-C21D-12 Eaton Vickers Quiet Piston Pump 41cc 210bar

Product Overview

The PVQ13 / PVQ20 / PVQ40 series (typical models PVQ40-B2R-SE1F-10-C21D-12, PVQ20-B2R-SE1S-21-C21-12, PVQ13-A2R-SS) is an Eaton Vickers PVQ quiet-series variable-displacement axial piston pump designed for open-circuit industrial applications. Displacement is infinitely variable via pressure compensator; flow is proportional to drive speed and displacement. The unit offers 100% drop-in interchangeability with genuine Vickers / Eaton pumps—no piping or mounting modifications required. Every unit undergoes full simulated operating-condition testing to guarantee low noise, high efficiency and long service life.

Key Technical Advantages

1. Precision-machined swashplate and rotary group combined with quiet-series optimisation deliver significantly lower noise levels than conventional piston pumps.
2. Fast-response pressure compensator automatically adjusts flow to load, reducing energy consumption and heat generation.
3. High volumetric efficiency is maintained at rated pressure, ideal for continuous industrial duty.
4. Long-life bearings and wear-resistant materials support a wide range of hydraulic fluids (mineral, synthetic, water-glycol, etc.) for excellent versatility.
5. 100% interchangeability plus full operating-condition testing ensures exact match of mounting dimensions, ports and control characteristics with original Eaton Vickers PVQ units, minimising downtime.

Application Areas

Designed for open-circuit systems in industrial power units, machine tools, injection moulding machines, presses, test stands and other applications requiring low-noise, medium-to-high pressure variable flow.

Expert Maintenance Tips

1. Before installation, confirm rotation direction (R = clockwise) and shaft type match; ensure precise flange alignment to avoid radial loads.
2. Fully bleed the system before first start-up. Use hydraulic fluid meeting Eaton specifications; recommended cleanliness ISO 4406 18/16/13 or better.
3. Periodically check case pressure (maximum 0.35 bar) and inlet pressure; verify correct control settings.
4. When changing filters and oil, inspect the pistons and valve plate for wear. Perform preventive maintenance if flow decreases or noise increases to maximise hydraulic-system longevity.
