The PVQ5-1X/154RA15DMC fixed-displacement pump is produced by Bosch Rexroth within the PV Fixed Displacement Pumps series. It supplies a constant volume of hydraulic fluid for automated presses, injection machines, or steering circuits that demand predictable flow. The unit displaces 153.5 cm3/rev, giving a rated flow of 223 l/min when driven at 1500 rpm. Stable operation begins at 600 rpm, and the shaft turns clockwise, allowing direct coupling to engines or electric motors that share the same rotation. Installation is handled with an SAE-C 127-2 flange in accordance with SAE J744, while the pressure outlet sits on the top face, 0° from the inlet, and is threaded for an SAE 1 1/2 in connection. The suction side accepts an SAE 3 in line to reduce inlet losses. System fluid must meet ISO 4406 class 20/18/15 cleanliness to protect internal surfaces.
Continuous service is permitted up to 175 bar at the outlet, enabling the pump to drive actuators that require moderate working pressure without oversizing. Fluid temperatures may range from –10 °C to 70 °C, so the circuit can start reliably in cold environments yet remain stable under typical operating heat. Viscosity limits span 13 mm²/s at the low end to 860 mm²/s at the high end; this range defines the acceptable thickness of the oil for efficient volumetric sealing and bearing lubrication. A minimum absolute inlet pressure of 0.83 bar prevents cavitation at the suction port during high flow demand. By adhering to these parameters, designers can keep internal wear low and maintain volumetric efficiency throughout the pump’s service life, ensuring that the PVQ5-1X/154RA15DMC remains a consistent source of hydraulic energy within automated machinery.
