  2. MDS Series hydraulic motors are designed for high power and high speed applications. MDSseries These motors are exclusively developed for Wagon Tippler, Side Arm Charger & Paddle Feeder Hydraulic Drive Application due to high radial & Axial Load capacity. In addition, these motors are also most suited for use in Feeder Breaker, Ball Mills and Bowl Mills. Optionally, a brake can be fitted in the rear end of the motor. The motor displacements available range from 9 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 the incorporation of a robust front bearing arrangement. Options aCustomized shaft aIntegral multi plate disc brake aHigh speed versions aDouble shaft aSuper low noise aCorrosion resistant material aThrough hole shaft of various sizes aCustom finish aDeep water submersible aNon magnetic material aDual displacement Features aLong life aHigh mechanical efficiency aConstant torque output aSmooth low speed performance<1rpm aResistance to thermal shock aDouble shaft sealing aShrink disc coupling aShaft or flange mounting aShock resistance aLow noise SPECIFICATION MOTOR FRAME SIZE TORQUE (THEORETICAL) TORQUE MAX SPEED RATED SPEED MAX** PRESSURE RATED DISP(*) PER REV METRIC CM3/REV NM/BAR NM RPM RPM BAR HMS 9.0 9080 144 47520 80 120 345 HMS 13.5-15 13540 215 70950 75 110 345 **High speed version upon request. * Any other displacement upon request. 9
