The PVB45FRSF20CM11 piston pump is produced by Vickers for the PVB Piston Pumps series. It supplies hydraulic power to automated machinery that relies on constant pressure and defined flow. Geometric displacement is 94.5 cm³ per revolution, letting designers calculate output volume precisely. At its rated speed of 1800 r/min, the pump delivers 170.3 L/min to cover medium-flow requirements. Maximum operating pressure is 100 bar (1500 psi), so it handles moderate working loads without overstress. Clockwise shaft rotation aligns with standard right-hand prime movers. Foot mounting secures the housing on a base plate for straightforward alignment. Fluid enters and leaves through flanged main ports, and the SAE 4-bolt flange interface keeps port geometry consistent across installations.
Operating limits begin with an ambient temperature band from −20 °C to +70 °C, enabling use in unheated plants and warm equipment rooms. Acceptable fluid viscosity ranges from 13 cSt to 220 cSt, which protects internal parts during cold starts and high-temperature running. The drain port is threaded 1.0625-12 UNF-2B, giving a standard outlet for case leakage return lines. Overall length is 407.0 mm, information needed for cabinet or skid layout. A pilot diameter of 152.4 mm centers the pump against the mounting surface to control shaft alignment. Displacement is adjustable on one side of center, simplifying the control mechanism when only a single flow direction is needed. These physical details combine to create a pump envelope that integrates cleanly with standardized hydraulic drives.
