MPGB020HTYZ46EZFS1HA10045DRKNN1DR

The MPGB020HTYZ46EZFS1HA10045DRKNN1DR unit belongs to the MPGB-A10VSO Close-Coupled Motor Pumps series and is produced by Bosch Rexroth. It couples an A10VSO variable-displacement pump to a three-phase motor for hydraulic automation tasks. A pump displacement of 45 cc per revolution determines the volume delivered per shaft turn, while a rated flow of 20 gpm supports medium-capacity circuits. The assembly sustains 1,500 psi at full flow, allowing actuators to work against moderate system loads. A 20 HP motor supplies the required input power, and its 60 Hz rating matches standard North American mains. The winding is designed for 208–230/460 V operation so users can select either low- or high-voltage connection. Motor frame size 256TYZ sets the mechanical outline for installation, a totally enclosed fan-cooled construction shields the winding from airborne contaminants, and the pump uses the DR control type.

The pressure outlet uses a 1.00 in Code 61 flange to connect directly to downstream piping, whereas the suction inlet employs a 1.50 in Code 61 flange to maintain adequate fluid supply to the pump. A case drain port threaded for SAE 10 (7/8-14 UNF-2B) carries excess leakage oil back to the reservoir, preventing housing overpressure. The dedicated DR port, sized SAE 04 (7/16-20 UNF-2B), provides an external interface for pilot control lines. Because the build includes no thru drive, the shaft cannot be used to power auxiliary pumps, which simplifies alignment and reduces overall length. These connection sizes and drive provisions focus the unit on single-circuit hydraulic power packs where compactness and standardized ports speed installation.
