The PVV5-1X/139RA15UMC belongs to the PV Fixed Displacement Pumps series from Bosch Rexroth and supplies hydraulic circuits with a constant volume per turn. Its displacement of 138.6 cm³ per revolution sets the basic delivery rate, yielding a flow of 203 L/min when the drive speed is 1500 min⁻¹. The unit works between 600 and 1800 min⁻¹ at an inlet pressure of at least 1 bar absolute, so prime movers can select a wide operating band without cavitation. Clockwise rotation must be maintained for proper port alignment, and the large SAE 3 in. suction connection keeps inlet velocity low. HLP mineral oil specified by DIN 51524-2 is the required fluid, and it must be filtered to ISO 4406 class 20/18/15 to protect internal surfaces.
The model sustains a continuous outlet pressure of 175 bar, letting it drive medium-pressure actuators without overstressing housing or bearings. A drive-shaft torque limit of 610 N·m defines the maximum mechanical load that can be applied from the prime mover. Installation uses an SAE-C 127-2 flange, providing a standardized pilot diameter and bolt circle for quick interchange. Discharge flow exits through an SAE 1 1/2 in. pressure port that matches common high-pressure fittings. Fluid temperature must stay between −10 °C and +70 °C so viscosity remains within the pump’s design window and sealing materials are not damaged.
