The PVB6 RSY 20 CM 11 pump belongs to the PVB Piston Pumps series and is produced by Vickers for hydraulic automation systems. The unit is a variable displacement axial piston pump that supplies controlled flow while maintaining clockwise rotation. Its geometric displacement is 13.81 cm³ per revolution, and the displacement control acts on one side of center so flow increases from a neutral position in a single direction. When operated at 1800 rpm the pump provides a nominal flow of 22.7 L/min, and it draws 26.1 kW of input power at 140 bar. System pressure can be adjusted up to 100 bar (1500 psi), giving the pump the headroom required for medium-duty hydraulic circuits.
Ambient operating limits run from −20 °C to +70 °C, enabling use in both cold storage areas and warm production halls. The rotating assembly tolerates speeds up to 3600 rpm, allowing high-speed drives with compact electric motors. Sound emission is 58 dB(A) at 1500 rpm and 70 bar, supporting installations that observe workplace noise guidelines. For clockwise rotation the inlet is Port A and the outlet is Port B, and both working ports are tapped 11/16-12 UNF-2B to accept common hydraulic fittings. A separate case drain line is provided with a 9/16-18 UNF-2B thread to route leakage flow back to tank and keep housing pressure low. These connection details and environmental ratings make the pump straightforward to integrate into manifolds and servo-controlled hydraulic systems.
