The PVV2-1X/045LD pump is manufactured by Bosch Rexroth and belongs to the PV Fixed Displacement Pumps series, supplying constant flow for hydraulic automation systems. Build size 2 defines the overall housing and shaft geometry suited to medium-duty power units. A displacement of 45.4 cm³ per revolution specifies the volume moved each shaft turn, and a flow of 66 l/min at 1500 rpm provides steady throughput for actuators. The unit withstands a maximum continuous pressure of 175 bar so circuits can operate without pressure relief during normal loading. A minimum speed of 600 rpm prevents internal cavitation by maintaining lubrication. The shaft must turn in an anti-clockwise direction to match the internal gear form. Flange mounting to SAE J744 enables direct coupling to standard electric-motor adapters.
A minimum absolute inlet pressure of 0.9 bar keeps the suction side above vapor pressure to avoid aeration. The pump is filled with HLP mineral oil according to DIN 51524-2 to preserve seal integrity and viscosity range. ISO 4406 cleanliness class 20/18/15 is required to limit particle-induced wear on the sliding plates. An SAE-B mounting flange maintains shaft alignment with common prime movers, while the pressure port is SAE 1″ positioned on the top at 0° from the inlet to simplify rigid piping. Suction oil enters through an SAE 1 1/2″ connection that minimizes velocity and pressure drop. The assembled pump weighs 14.8 kg, permitting single-person handling during installation.
