Fluid Coupling Working Principle As the electric motor accelerates to the running speed, the impeller begins to centrifugally pump oil to the stationary runner. Transmission of oil is diffused by the conical impeller baffle, producing a gradual increase in torque, allowing the motor to accelerate rapidly to full running speed.

A hydraulic unit allows the watertightness between the plates at the surface of the joints. By means of a cylinder, the hydraulic unit keeps the balance between the plates squeezing and the filling pressure induced by the feeding pump throughout the filtration process. Under this pressure, the liquids pass through the filter cloth that hold the

The movement of the floating roller constitutes the basic principle of a roller press. The extent of the roller movement (roller gap) is a function of the pressing force generated by the hydraulic system in relation to the reaction forces exerted by the material being processed and the preset "zero-position" of the roller gap.
