Product Description



SMF Hydraulic Axial Piston Concrete Motor MF2 MF20 MF21 MF22 MF23 MF24 MF25 MF26 MF27 with swashplate construction are of swash plate construction with preset displacement. and are intendent for closed circuit operation. The output speed is propor tional to the flow rate of the input fluid. The output torque is proportional to the differential between high and low pressure sides of the fluid circuit. The direction of motor (output) shaft rotation depends upon which port the fluid enters the motor.

Details regarding the choice of hydraulic fluid    
The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in a closed circuit the circuit temperature. The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimum range - the shaded area of the selection diagram.  the higher viscosity class be selected in each case. i, e: At an ambient temperature of X °C an operating temperature of 60 °C is set. In the optimum operating viscosity range (shaded area) this corresponds to the viscosity classes VG46 or VG68; to be selected: VG65. and note: The case drain temperature, which is affected by pressure and speed, is always higher than the circuit temperature. At no point in the system may the temperature be higher than 100 °C. If the above conditions cannot be maintained due to extreme operating parameters, please consult us.
