The PVQ5-1X/162R pump belongs to the PV Fixed Displacement Pumps series from Bosch Rexroth. It is a fixed displacement vane pump that supplies constant flow for hydraulic automation circuits. The displacement is 162.2 cm³ per revolution, so each shaft turn delivers a defined oil volume to downstream actuators. The unit runs with clockwise rotation, yet the inlet and outlet positions remain independent of rotation to simplify line routing. When inlet pressure is 1 bar, permissible speed reaches 2500 min⁻¹, and reliable delivery begins at 600 min⁻¹ for low-speed drives. At 1500 min⁻¹, the pump provides 234 l/min, supporting medium-capacity systems. Continuous outlet pressure capability is 210 bar, allowing stable force transmission to cylinders and hydraulic motors without overstressing internal vanes.
The pump mounts by flange according to SAE J744, and the mounting flange is classified as SAE C for compatibility with common power-unit frames. Pressure discharge is routed through a 1 1/2-inch SAE port, while a 3-inch SAE port serves the suction side to limit inlet losses. Both ports accept piping via SAE flanges secured with UNC screws, easing installation and maintenance. The hydraulic circuit must use HLP mineral oil defined in DIN 51524-2, and fluid cleanliness must reach ISO 4406 20/18/15 to preserve vane and bearing life. The assembly weighs 34 kg, allowing handling with standard shop equipment. These interface and fluid requirements help the PVQ5-1X/162R integrate into existing hydraulic power units.
