The PVV52-1X/139-040RJ15UUMC is produced by Bosch Rexroth for the PV Fixed Displacement Pumps series and supplies pressurized fluid to hydraulic automation circuits. It turns clockwise, a requirement that defines motor orientation in the drive train. A displacement of 138.6 cm³ per revolution on the flange side establishes the volume moved each rotation, while a flow of 203 l/min at 1500 rpm on that same side indicates the delivery rate at common motor speed. Continuous operation is limited to 175 bar to protect internal components from overload, and the unit may run up to 1800 rpm without exceeding design limits. Power transfer is handled through an SAE-C 1 1/4-inch, 14-tooth, 12/24 DP spline shaft that matches standard prime movers. Installation is completed with an SAE J744 flange, allowing direct mounting to compatible housings in industrial machinery.
The pump weighs 46 kg, a factor that influences support structure sizing and service handling. On the cover side it displaces 40.1 cm³ per revolution, producing 59 l/min at 1500 rpm for auxiliary circuits that need lower flow. Maximum input shaft torque reaches 818 Nm, defining the drive power required to achieve rated pressure and speed. Reliable low-speed performance begins at 600 rpm, and inlet conditions must stay above an absolute pressure of 0.83 bar to prevent cavitation. Fluid temperatures can range from −10 °C to +70 °C, and viscosities are permissible up to 860 mm²/s, enabling the unit to operate with a broad selection of hydraulic oils under varying ambient conditions.
