The PVV2-1X/045RA15UMB pump belongs to the PV Fixed Displacement Pumps series and is manufactured by Bosch Rexroth for closed-loop hydraulic automation circuits. It delivers a fixed displacement of 45.4 cm³ per revolution so the flow output is proportional to speed. At a typical input of 1500 rpm it supplies 66 l/min, providing stable actuator movement. The unit supports a continuous pressure of 175 bar, allowing operation in medium-pressure systems without overloading the housing. Clockwise rotation is specified to ensure correct shaft alignment with standard drive motors. Permitted speed spans from 600 rpm to a maximum of 1800 rpm at 1 bar inlet, giving designers flexibility when selecting prime movers. The pump is intended for HLP mineral oil conforming to DIN 51524-2, which matches the internal sealing compounds and wear surfaces. A cleanliness class of ISO 4406 20/18/15 is required so that particle levels stay low enough to prevent abrasion of the gear set.
The SAE-B (101-2) mounting flange simplifies attachment to common industrial engines while keeping alignment precise. System oil enters through an SAE 1 ½ in suction port sized to minimize inlet velocity and reduce cavitation risk, and it leaves through an SAE 1 in pressure port located on the bottom, 180 degrees from the inlet, to streamline hose routing in horizontal installations. An NBR seal package contains fluid and withstands the specified mineral oil without swelling. The model is supplied without a through drive, so it cannot power additional hydraulic pumps in tandem arrangements. Total mass is 14.8 kg, which aids single-person handling during maintenance.
