PVV1-1X/036RJ15DMB A261

The PVV1-1X/036RJ15DMB A261 pump is produced by Bosch Rexroth within the PV Fixed Displacement Pumps series and is intended to supply constant flow in hydraulic automation circuits. It delivers a displacement of 36.4 cm³ per revolution, so each shaft turn moves a defined oil volume for predictable actuator motion. At 1500 rpm it reaches a flow of 53 l/min, providing adequate supply for medium-size systems. The pump withstands a continuous pressure of 210 bar, allowing it to drive cylinders and motors that require high working pressure. A permissible shaft torque of 316 Nm guides selection of the prime mover and coupling. Maximum operating speed is 1800 rpm when the inlet pressure is 1 bar, which limits cavitation risk at high rotational velocity. The minimum speed of 600 rpm preserves internal lubrication during slow cycles, while an inlet absolute pressure as low as 0.83 bar supports reliable suction. A SAE 3/4 pressure connection simplifies integration with standard hydraulic lines.

The unit is designed for HLP mineral oil specified in DIN 51524-2, ensuring compatibility with common industrial hydraulic fluids. It tolerates fluid temperatures from -10 °C to 70 °C, so the reservoir heater or cooler must keep oil inside this range. Acceptable viscosity spans from 13 mm²/s to 860 mm²/s, enabling operation with fluids that maintain suitable thickness across seasonal changes. The pressure port is located on the top at 0° from the inlet, a layout that influences manifold arrangement and hose routing. Clockwise rotation is required, so drive orientation must match this direction to maintain correct internal timing. These installation parameters, together with the earlier performance limits, allow designers to match the pump to power units, set temperature control measures, and verify that fluid properties stay within the stated windows during all duty cycles.
