The PVB15-RS-31-C-11 piston pump is produced by Vickers within the PVB Piston Pumps series and is intended for hydraulic automation circuits requiring steady displacement and pressure regulation. A geometric displacement of 33.00 cm³/rev (2.01 in³/rev) determines the volume moved each shaft turn, while a rated flow of 59.4 L/min (15.7 gpm) at 1800 r/min supports moderate-capacity actuator groups. The unit can turn up to 3600 r/min, allowing designers to pair it with high-speed prime movers when compact power density is needed. Clockwise rotation defines the correct drive orientation, and an SAE mounting flange provides a standard interface for engine or motor housings. Pressure control is handled by a pressure compensator designated as style C, and the control design number 11 identifies the internal spring and spool arrangement used for that function. Ambient limits from −20 °C to +70 °C permit installation in both chilled and elevated temperature zones without additional heaters or coolers.
For load holding and relief tasks, the pump can generate up to 2000 psi, enabling service in medium-pressure mobile and industrial machines. When a 5/95 water-in-oil emulsion is the working fluid, maximum pressure is restricted to 70 bar (1000 psi) to protect wear surfaces. The maximum input demand of 29.4 kW (39.5 hp) at rated pressure and speed helps size the driving electric motor or engine. One-side-of-center displacement zoning maintains smooth flow in closed-center directional valve arrangements. Anti-wear oils, water glycols, and invert emulsions are all permissible fluids, which simplifies fluid selection across mixed equipment fleets. A typical noise level of 69 dB(A) measured at 1500 r/min and 140 bar assists system designers in meeting workplace sound targets without extensive acoustic treatment.
