The PVV2-1X/045R pump is manufactured by Bosch Rexroth within the PV Fixed Displacement Pumps series for hydraulic automation. It delivers a geometric displacement of 45.4 cm³ per revolution, enabling predictable volumetric output. At 1500 rpm it can supply 66 L/min, a flow suitable for medium-duty cylinders and motors. The unit operates between 600 and 1800 min⁻¹ so system designers can match different prime-mover speeds. Clockwise rotation aligns with common drive arrangements in power units. HLP mineral oil according to DIN 51524-2 is the approved working fluid, ensuring seal compatibility. A cleanliness class of ISO 4406 20/18/15 is required to limit wear from particulate contamination.
The direction of flow is independent between inlet and outlet ports, allowing flexible line routing. A minimum absolute inlet pressure of 0.83 bar must be maintained to prevent cavitation. The casing tolerates 175 bar continuous pressure, supporting long duty hydraulic cycles. A SAE-B (J744) mounting flange provides standardized attachment to motors or bellhousings. Pipe interfaces follow the SAE flange version with UNC threads for straightforward assembly. The pressure port uses a SAE 1-inch connection while the suction side is sized for SAE 1-1/2-inch plumbing to keep inlet velocity low. Total mass is 14.8 kg, so a single technician can position the pump during installation.
