The sealing action is accomplished by leading in clean compressed water for lifting up the rubber piston to press against the stainless steel wearing plate which is rotating together with the main spindle,so that the water will not flow into the machine pit and leakage is prevented.The structure is simple,tight and wear resistant,very easy for maintenence and the replacement of sealing components,no abrasion on the big shaft and the the sealing component is of automatic compensation type.The compressed water used for the sealing action is from technical water supply; water pressure is between 0.2 to 0.4 MPa and the water consumption is about 200 litres per minute.
