ABSTRACT:
The invention relates to a split seal device for use between a stationary body and a rotary body. The device utilizes a fractured seal ring which is fractured along two diametrically opposite uneven fracture lines to prevent leakage of fluid. A vulcanized rubber insert which circumferentially engages the outer surface of the split ring is cut along about at least one split line and is fitted within a rotary housing, the latter being designed for mounting on a rotating shaft. The fractured split ring has a contact face for frictional contact with a corresponding contact face of a seal ring of the stationary body. The seal ring is likewise fractured along two diametrically opposite uneven fracture lines and is retained adjacent innermost end of the stationary body. To decrease shock of rotation, the lugs which engage the rotary face to the rotary housing, are made flexible and resilient. The split seal device is mounted for engagement with the flexible lugs in general co-axial alignment with the rotating body. The stationary portion has a two-part flange which is fixedly removably attached to a fluid containing vessel. An elastomeric insert is inserted between two parts of the flange.
