Medium Duty Piston Motors

Mobile applications-Medium Duty Piston Motors

First known as MD-CC products, Eaton medium duty closed circuit piston pumps and motors have been in production since the 1960s. Together, the pump and motor are generally referred to as a hydrostatic trans-mission, or HST, which can provide continuous rotary motion at a remote location from the power source.

This capability makes them ideal for the unique and demanding requirements of off-highway vehicles. They are best suited for applications using mid-range, less than 63.4 kW (85 HP), engines operating at less than 380 Bar (5500 PSI) system pressures. 

Eaton’s Medium Duty Piston motors are available in 3 fixed (741XX, 743XX, 746XX) displacement and 2 variable (713XX, 72450) displacement models.
