The P2R4-3X/5 00-500RK01M01+AZPF16 is a hydraulic pump assembly in the PR Radial Piston Pumps series from Bosch Rexroth, designed to supply both high-pressure and auxiliary flow within automated power units. A radial stage delivers 4.82 cm³ per revolution, and its three pistons stabilize pressure pulsations while keeping the unit compact. Continuous operation is permitted between 1 000 and 2 000 rpm; the lower limit sustains internal lubrication, and the upper limit protects rotating parts from excess centrifugal load. The radial section produces up to 500 bar, letting it drive cylinders that demand high force with minimal footprint, and the drive must transmit up to 160 Nm of shaft torque when that pressure is reached. A cylindrical shaft with an AZPF output profile simplifies direct coupling to standard motor flanges, and clockwise rotation aligns with right-hand power-takeoff arrangements.
The integrated gear stage complements the radial section by moving 16 cm³ per revolution to feed pilot lines and cooling circuits. Its continuous pressure rating is 250 bar, while a 280 bar intermittent limit handles short overloads without damage, and the housing endures 300 bar peaks caused by rapid valve shifts. Flow can be increased safely to 3 000 rpm at port P2, supporting machines that cycle quickly. One pressure port streamlines plumbing, and the connection is a Pipe Thread per ISO 228-1 so installers can use standard fittings. NBR sealing elements contain mineral oil and resist common hydraulic additives, preserving service life under industrial duty cycles.
