MAH 6.3 and 12.5 are high-speed motorsoperated by water hydraulics. The hydraulicmedium is ordinary tap water. The motors baseon the axial piston principle that enables a lightand compact design. The water lubricates allmovable parts in the motor, and there is thus no need for special oil lubrication.The motors vary in size from 6.3 cm³ to 12.5 cm³ per revolution (rated displacement).The maximum operating torques vary from12.5 Nm to 25 Nm and maximum outputs from5 kW to 8 kW.
