The MPGB020HTYZ4DEOFS1AZPF22028K1NN motor pump is produced by Bosch Rexroth in the MPGB-AZPF Close-Coupled Motor Pumps series to circulate hydraulic oil in automated machinery. It employs a fixed external gear pumping element, giving straightforward volume transfer without variable timing. A 20 HP rating supplies the torque needed for continuous duty in presses and material-handling lines, while the 28 cc per revolution displacement sets the delivered volume per shaft turn for predictable output. A four-pole stator defines the synchronous speed class, balancing torque density with moderate rpm, and the 256TYZ frame lets the unit mount to standard bases. The totally enclosed fan-cooled enclosure shields windings from dust and moisture yet maintains housing airflow. At 50 Hz the shaft turns near 1450 rpm, and at 60 Hz it reaches about 1750 rpm, giving two common operating points for matching flow requirements.
The pump develops a maximum flow of 13.3 gpm (50.4 L/min) to supply medium-size cylinders and motors, and it sustains 3020 psi (208 bar) at full flow for high-pressure circuits. A SAE-10 pressure port with a 7/8-14 UNF-2B thread accepts standard hose fittings, while the suction side uses a larger SAE-16 port threaded 1-5/16-12 UN-2B to reduce inlet losses during cold starts. An overall length of 25.28 in suits compact power units where depth behind guards is limited, and the assembled package weighs 285 lb, so rigging points or hoists are advised for safe installation.
