PSS 02-105M-700 - Dripless Shaft Seal 105 mm, 7" Stern Tube
The PSS 02-105M-700 Dripless Shaft Seal is engineered for reliable performance in marine applications. It features a mechanical face seal that effectively prevents leakage between the rotating and stationary components.
This system utilizes a stainless-steel rotor that creates a sealing surface against a stationary carbon flange. The carbon flange is securely attached to the bellow using hose clamps, while the bellow itself fits snugly over the stern tube. The rotor compresses the bellow, ensuring a tight seal maintained by set-screws. This design allows the seal to adapt to the dynamic movements caused by propeller thrust, ensuring consistent performance.
Moreover, the carbon flange is precision-engineered to float around the shaft, accommodating misalignments and vibrations. The stainless-steel rotor is equipped with dual O-rings that are recessed within the collar, providing an effective seal without experiencing wear during operation. This innovative design minimizes maintenance needs and enhances the longevity of the seal.
