Fixed displacement motors of the HMF-02 type are suitable for both open and closed loop circuit.
Two porting options and a variety of equipment options are available for this motor o ensure the best possible adaptation to your specific application.
The use of dual pressure crossover relief valves broadens the spectrum of possible applications. The low setting of the relief valve permits soft gentle braking of the motor. When the relief valve is triggered to its high setting, maximum acceleration and braking torque is available at the motor. A typical application of this type is a turning and boring mill drive.
