HF hydraulic motors are of the hydrostatically supported-axial-piston, high-speed, fixed-displacement type.
However they can work at low speed with a steady rotation as the result of the high number of pistons on which the torque is divided and of a particular patented tining system. Those motors can start under load supplying a constant torque directly proportional to the operating pressure and irrespective of the speed of rotation.
The high exercise pressure and the speed of rotation makes it possible to obtain high total efficiency consents the best exploitation of the installed power thus reducing the energy costs.
