The MPGB020HTYZ46EZFS1HA10028DRKNN1DR pump-motor unit belongs to the MPGB-A10VSO Close-Coupled Motor Pumps series from Bosch Rexroth and combines an electric drive with a hydraulic pump for automated fluid power circuits. It runs on 60 Hz, three-phase supplies at 208–230/460 V, making it compatible with common industrial power grids. A 20 HP motor in the 256TYZ frame furnishes mechanical energy, and the shaft speed is 1750 rpm at the rated frequency to keep rotational dynamics predictable. The pump uses an axial piston, variable displacement design so flow can be changed without altering motor speed, while each revolution moves 28 cc of oil to establish base delivery. Horizontal mounting positions the assembly in line with machine frames, and the model is supplied without a through drive, limiting power transmission to the primary circuit only.
During operation the unit provides up to 13 gpm (49 L/min) at full displacement and sustains 2400 psi (165 bar) to meet moderate-pressure hydraulic tasks. A 3/4 in Code 61 flange carries the pressure line, and a 1.25 in Code 61 flange handles inlet flow to reduce suction losses. The suction opening faces downward in line with the feet so oil enters under gravity, reducing the risk of cavitation at startup. Damping rails under the base absorb vibration and lower transmitted noise, protecting surrounding structures and extending bearing life.
