The PVB15 RSY 31 C 11 piston pump is produced by Vickers within the PVB Piston Pumps series and supplies variable flow for hydraulic automation circuits. The model uses a pressure compensator to regulate outlet pressure and maintain system stability. Its geometric displacement is 33.00 cm³ per revolution, allowing 2.01 in³ of fluid to move each cycle. When driven at the rated speed of 1800 r/min, it delivers a maximum flow of 59.4 L/min (15.7 gpm), which supports medium-capacity actuators. The pump needs 29.4 kW of input power at high pressure and 1800 r/min, corresponding to 39.5 hp. Continuous service is allowed up to 140 bar (2000 psi), matching common industrial hydraulic demands. Rotation is clockwise, so the drive coupling must match this direction. The swashplate operates on one side of center to achieve displacement control, and the housing mounts on a standard SAE flange for direct connection to most electric motors.
The unit operates in ambient temperatures from -20 °C (-4 °F) up to +70 °C (+158 °F), enabling deployment in indoor and sheltered outdoor machinery. Mineral oil temperature may rise to +80 °C (+176 °F) without affecting service life, provided the fluid meets the ISO 18/14 cleanliness class to protect internal bearings and pistons. At 1000 r/min and 210 bar, airborne sound pressure is 60 dB(A), while running at 1500 r/min and 140 bar the level increases to 69 dB(A); these values assist designers in meeting workplace noise limits. Hydraulic cleanliness, temperature allowances, and the stated noise ratings define the environmental envelope and maintenance schedule for this pump.
