PVV2-1X/068RJ15UMB

The PVV2-1X/068RJ15UMB is a fixed displacement pump in the PV Fixed Displacement Pumps series from Bosch Rexroth. It supplies a constant flow for hydraulic automation such as press drives and machine tools. The displacement is 67.5 cm³ per revolution, so output volume is predictable for every shaft turn. When driven at 1500 rpm it delivers a maximum flow of 100 L/min, supporting actuators that need steady medium-volume supply. The permitted speed spans from 600 to 1800 min⁻¹, giving flexibility in matching electric or diesel prime movers. Clockwise rotation is specified, which determines shaft arrangement relative to the inlet and pressure ports. Continuous operating pressure reaches 175 bar, enabling closed-loop circuits at moderate working loads. A minimum absolute inlet pressure of 0.83 bar is required to protect against cavitation in the suction line. The unit uses an SAE-B mounting flange, allowing direct coupling to standard SAE B motor faces.

For circuit plumbing, the pressure port is sized to SAE 1 in, establishing an outlet interface that withstands the rated pressure, while the suction port is SAE 1 ½ in to keep inlet velocity low and maintain prime. The pump handles mineral oils with viscosities from 13 mm²/s up to 860 mm²/s, so it tolerates cold starts and high operating temperatures without loss of lubrication. Fluid temperature limits from –10 °C to +70 °C align with typical hydraulic oil specifications and prevent seal degradation. These temperature and viscosity capabilities simplify selection for industrial and mobile equipment exposed to seasonal changes. The assembled mass is 14.8 kg, light enough for single-person installation yet robust for continuous duty. Collectively, these characteristics define the operating envelope and connection requirements of the PVV2-1X/068RJ15UMB within hydraulic automation systems.
