MD SERIES - Description


MASCOT MD series hydraulic motors are designed for high power and high speed applications. Most of the belt conveyors are driven by MD series motors. In addition, these motors are most suited for use in Feeder Breaker, Ball Mills and Bowl Mills. Optionally, a brake can be fitted in front end of the motor.

The motor displacements available range from 8 lit/rev. to 15 lit/rev. They aim to provide a wide variety of precise hydraulic motor and pump combinations. These motors can take heavy shock loads due to incorporation of robust front bearing arrangement.
