It is mechanical seal device that controls specific pressure of fiction on contact surface by corrugated tube expansion, it is mainly used in boats, especially high-speed boats, and it confirms to GJB2479-95 General code for stern tube seal of boats.
Simple structure, small amount of parts.
Heat-resistant and wear-resistant materials for stationary seal ring.
No friction to the propeller shaft and sleeve.
Long service time: due to flexibility of the corrugated tube, specific pressure changes slightly when axial vibration rises.
Be able to operate in water with high silt content.
Propeller shaft linear velocity ＜6m/s.
Propeller shaft axial travel ＜8mm, axial play 4mm.
Propeller shaft radial jump: ±3mm.
Low water leakage: below 40L/day, No water drop can be seen in navigation pause, or only a little.
