The PVV2-1X/068RA15UMB pump is produced by Bosch Rexroth within the PV Fixed Displacement Pumps series and supplies constant volume flow for hydraulic automation circuits. The unit provides a displacement of 67.5 cm³ per revolution, giving predictable output for actuators that require steady motion. At 1500 rpm it reaches a flow of 100 l/min, allowing medium-sized systems to move cylinders at consistent speed. A maximum operating speed of 1800 rpm at 1 bar inlet enables higher cycle rates when needed. The pump sustains 175 bar continuous pressure so pipelines and valves can be sized for that working limit without intermittent derating. Clockwise rotation matches common electric motor drives, while a minimum absolute inlet pressure of 0.83 bar prevents cavitation during suction. The hydraulic fluid must keep a viscosity above 13 mm²/s to maintain film strength in the internal gear set.
SAE J744 flange mounting positions the PVV2-1X/068RA15UMB directly on standard motor bell housings, and the flange follows the SAE-B 101-2 outline to align the shaft without shims. Pressure is discharged through a bottom-oriented port which simplifies vertical installation in power units. All ports are cut to SAE dimensions and retained with UNC screws, reducing adapter requirements during hose routing. The NBR seal material is compatible with common mineral oils and withstands service up to a fluid temperature of 70 °C. Cleanliness class ISO 4406 20/18/15 is required so that bearing and gear surfaces avoid abrasive wear over the pump life. A weight of 14.8 kg allows a single technician to position the pump without lifting equipment.
