The P2R4-3X/10 00-500RK01M01+AZPF25 is supplied by Bosch Rexroth within the PR Radial Piston Pumps series for hydraulic automation that demands precise high-pressure flow. Two pumping sections share a common housing, and together they displace 35.0 cm³ per revolution. Section 1 contributes 10.00 cm³ per revolution and must turn clockwise, so the drive motor has to match this rotation. This section handles operating pressures up to 500 bar, enabling force-intensive actuators. Fluid leaves through a single pressure port that connects with ISO 228-1 pipe threads, simplifying integration with standard tube fittings. NBR sealing elements are used in this section to contain the working fluid and limit leakage under full load.
Section 2 delivers 25.0 cm³ per revolution and operates continuously at 195 bar while permitting intermittent peaks of 225 bar; it can run at rotational speeds up to 3000 rpm without derating. The hydraulic circuit can be extended through a cylindrical through-drive shaft, allowing an additional unit to be mounted in series. HLP oil according to DIN 51524 is the designated working medium, and the pump accepts fluid temperatures from ‑10 °C to +70 °C to support both cold starts and elevated operating conditions. These parameters let the unit maintain reliable volumetric output across varied duty cycles while the first section carries the higher pressure stage.
