The PVB10-RS-31-CG-20 pump belongs to the PVB Piston Pumps series manufactured by Vickers and provides regulated flow for hydraulic automation. It delivers 21.10 cm³ per revolution (1.29 in³/rev), and displacement occurs on one side of center as noted for this model. Rotation is clockwise when viewed from the shaft end, so drive orientation must match that direction. System pressure is controlled by a pressure compensator; the compensator can be adjusted from a minimum of 17 bar (250 psi) to a maximum of 210 bar (3000 psi) to protect downstream components. Remote pressure adjustment is enabled, allowing setpoint changes without direct access to the pump housing.

The pump operates with mineral oil, water glycol, or invert emulsion, giving users flexibility in fluid selection. Acceptable ambient temperature spans from –20 °C (–4 °F) to +70 °C (+158 °F). With mineral oil, fluid temperature may range between –20 °C (–4 °F) and +80 °C (+176 °F); with water-containing fluids, it should stay between +10 °C (+50 °F) and +54 °C (+129 °F). Systems using 95/5 water-glycol mixes must limit pressure to 70 bar (1000 psi). Noise output reaches 67 dB(A) at 1800 r/min and 210 bar during full-flow operation, supporting compliance with industrial sound guidelines.
