The PVV1-1X/018RA15UMB pump is manufactured by Bosch Rexroth and belongs to the PV Fixed Displacement Pumps series for closed-circuit hydraulic automation. It delivers a geometric displacement of 18.0 cubic centimeters per revolution, providing a predictable volume with every shaft turn. The pump sustains continuous operation at pressures up to 210 bar to support medium-duty power transmission loops. When driven at 1500 rpm it supplies a flow of 26 liters per minute, matching common industrial actuator requirements. Clockwise shaft rotation is required, so system designers must orient the drive accordingly. Installation is through an SAE J744 flange that conforms to the SAE-B 101-2 pattern, simplifying interchange with other standardized components. The housing weighs 12 kg and is sealed with NBR elastomers to resist common hydraulic oils.
The shaft can be accelerated to 1800 revolutions per minute at a 1 bar inlet without exceeding design limits. During low-speed cycles the unit still maintains reliable suction at 600 revolutions per minute. A permissible torque of 250 newton-meters can be applied to the drive shaft, supporting direct coupling to electric or diesel prime movers. Pressure fluid exits through a port located on the bottom side at 180 degrees, which helps compact manifold layouts. The pressure connection accommodates an SAE 3/4-inch fitting to carry flow at the rated pressure. Inlet oil is drawn through an SAE 1 1/2-inch suction port to minimize velocity and cavitation risk. Power transmission to the pump uses a keyed shaft with a key measuring 4.76 by 31.8 millimeters for positive torque engagement.
