The PVV1-1X/027RA15UMB pump belongs to the PV Fixed Displacement Pumps series and is manufactured by Bosch Rexroth for hydraulic automation tasks that require a steady flow at defined speeds. The unit displaces 27.4 cm³ of oil per revolution and sustains a continuous operating pressure of 210 bar. Rotation is clockwise when viewed from the shaft end, and drive torque is transmitted through a cylindrical shaft rated at 250 Nm. During operation the pump can run as high as 1800 rpm when the inlet pressure is at least 1 bar absolute, while stable function is maintained down to 600 rpm. The inlet side must see an absolute pressure of 0.83 bar or higher, and the hydraulic medium must have a viscosity of no less than 13 mm²/s.
At 1500 rpm, it delivers a flow of 39 L/min to downstream actuators. The working fluid may range from −10 °C to +70 °C, allowing the pump to serve equipment stationed in moderate ambient conditions. System plumbing connects to the pressure port through an SAE 3/4 in fitting that sits on the bottom face, positioned 180° opposite the inlet. Suction is taken through an SAE 1 1/2 in port that aligns with the housing intake. An NBR seal is fitted to keep leakage within allowable limits and to resist common hydraulic oils. These connection sizes, temperature limits, and port orientations support straightforward integration into compact power packs where predictable displacement and fixed delivery are required.
