The PVQ2-1X/045RA15UVB pump belongs to the PV Fixed Displacement Pumps series and is manufactured by Bosch Rexroth for hydraulic automation where a fixed delivery is needed. It supplies 45.4 cm³ per revolution, providing predictable flow to cylinders and motors. A cylindrical drive shaft transmits torque, and rotation is clockwise to align with common prime movers. The mounting flange follows the SAE-B (101-2) pattern, and the overall mounting style is the SAE J744 flange mount for direct coupling to power sources. Continuous working pressure is limited to 210 bar, the lowest operating speed is 600 min⁻¹, and the assembled unit weighs 14.8 kg.
A suction port sized SAE 1 1/2 feeds the pump, while the pressure port is SAE 1 and placed on the bottom 180° from the inlet to streamline hose routing. SAE flanges retained by UNC screws form the connection method and maintain seal integrity during service. The pump delivers 66 l/min at 1500 rpm and can run up to 2700 min⁻¹ when inlet pressure is 1 bar absolute. HLP mineral oil to DIN 51524-2 is the approved pressure fluid, and an FKM shaft seal resists heat and additives. These characteristics make the unit suitable for open-center or closed-loop circuits that require stable flow and straightforward installation.
