Product Overview
The BUCHER QXM31-025N (part number 100029144) is a high-performance internal gear motor from the Bucher Hydraulics QXM series, engineered for demanding industrial hydraulic drive applications. Operating on the internal gear principle, this motor converts hydraulic pressure and flow into reliable rotary mechanical output. Its design features a fixed-displacement internal gear set in which an externally toothed pinion rotates inside a larger internally toothed ring gear, with a filler piece separating the high- and low-pressure chambers. This architecture delivers smooth, low-pulsation torque across the full speed range, making the QXM31-025N an ideal drive solution for continuous-duty industrial machinery requiring compact installation, high starting torque, and dependable operation.
