Self lubricated shaft bearings (PTFE coated stainless steel) for both drive end and non-drive end shaft ensures minimum bearing friction torque. Square coupling disk drive arrangements eliminates need for taper pins and exposure of metal parts to media. Spherically profiled seat and disc shoulder contact area ensures perfect sealing around the shaft bore and zero leakage. External locking arrangement for top shaft to make it blow out proof. Seat liner extending on to the flange faces of the body eliminates the need for separate flange gaskets.
