PVV1-1X/018RJ15DMB

The PVV1-1X/018RJ15DMB pump belongs to the PV Fixed Displacement Pumps series from Bosch Rexroth and supplies constant hydraulic flow for automated circuits. Its displacement of 18.0 cm³ per revolution establishes the fixed volume transferred each shaft rotation, simplifying system sizing for actuators. The unit withstands a continuous pressure up to 210 bar so it can maintain force in presses and clamping devices without intermittent relief. Clockwise rotation is specified, allowing designers to orient the drive motor accordingly. Operation with HLP mineral oil according to DIN 51524-2 supports compatibility with standard industrial fluids. A minimum inlet absolute pressure of 0.83 bar prevents cavitation when the reservoir is below the pump centerline. The SAE-B (101-2) mounting flange aligns with common electric motor adapters for quick installation. Because the pressure port is on the top at 0° from the inlet and sized for an SAE 3/4-inch fitting, pipe runs can be kept short inside compact power units.

At 1500 rpm the pump delivers a flow of 26 L/min, providing sufficient supply for medium-sized cylinder groups in machine tools. The drive can reach 1800 min-1 when the inlet pressure is at least 1 bar, offering additional flow for transient peak demand, while a minimum speed of 600 min-1 protects internal bearings from boundary lubrication during slow cycles. A permissible shaft torque of 316 Nm defines the mechanical load that the coupling and prime mover must transmit. The suction port accepts an SAE 1 1/2-inch connection, enabling low velocity entry of fluid to reduce pressure drop. Fluid cleanliness should be held to ISO 4406 class 20/18/15 to limit wear on the sliding vane set. A mass of 12 kg allows a single technician to mount the unit without lifting equipment, completing the installation of this fixed displacement pump in automated hydraulic assemblies.
