MPG-AA10VSO28DFR25RF1V

The MPG-AA10VSO28DFR25RF1V is a close-coupled motor pump from Bosch Rexroth in the MPGB-A10VSO series, intended to supply controllable hydraulic power in automated machinery. It relies on an axial piston variable displacement design so the swashplate can vary flow to suit changing load demands. A geometric displacement of 28 cm³ per revolution fixes the volume moved on each shaft turn. When the shaft runs at 1800 rpm, the unit can provide up to 13 gpm (49 L/min) for medium-duty circuits. The integral motor is rated for 1800 rpm to match this pump speed precisely. Operation on 230/460 V, 60 Hz three-phase supply enables direct connection to standard plant power. A totally enclosed fan-cooled enclosure protects the motor against dust and dripping water to maintain service life.

DFR pressure control automatically tilts the swashplate to hold the commanded outlet pressure without external feedback devices. A 3/4 in Code 61 pressure flange handles the discharge flow safely at working pressure, while a 1.25 in Code 61 suction flange offers low-restriction fluid entry. Housing leakage returns through a SAE 06 (9/16-18 UNF-2B) case drain port to prevent excessive bearing loads. Remote pressure adjustment can be introduced through the SAE 04 (7/16-20 UNF-2B) DR control port. Electrical terminations are grouped at the F1 junction box location so wiring can be completed from one side of the assembly. Together, these interface points simplify installation and allow the pump to integrate cleanly into hydraulic automation systems.
