The MPGB020HTYZ4DEOFS1AZPF22028K1DR motor pump belongs to the MPGB-AZPF Close-Coupled Motor Pumps series from Bosch Rexroth and supplies hydraulic power where space and alignment simplicity are critical. A pump displacement of 28 cm³ per revolution defines the volume transferred each shaft cycle, while a rated flow of 13.3 gpm supports moderate actuator demands without cavitation. The assembly withstands 3020 psi at full flow so cylinders and motors can be driven at high working pressure. A totally enclosed fan-cooled (TEFC) enclosure blocks dust and moisture from the 20 HP induction motor, and its four poles establish the magnetic field that pairs with a synchronous speed near 1800 rpm. The delivered shaft speed of 1750 rpm at 60 Hz matches the gear set for the stated flow, and the dual-voltage winding accepts either 230 V or 460 V to ease connection in North American plants.
The motor uses frame size 256TYZ, allowing direct replacement with other NEMA units of the same footprint, and damping rails under the base limit vibration transmission to supporting structures. A downward-facing SAE-16 suction port (1-5/16-12 UN-2B) sits inline with the feet so the inlet hose can drop straight to a reservoir, reducing air entrainment, while the discharge leaves through an SAE-10 pressure port (7/8-14 UNF-2B) sized for the rated flow and pressure. Operation on either 50 Hz or 60 Hz mains lets the pump travel between regions without rewinding, and the 285 lb overall weight must be considered when selecting hoisting equipment or mobile bases. These features combine to create a compact, close-coupled source of hydraulic flow that minimizes alignment tasks and maintains consistent performance across common industrial power standards.
