The PSS 02-115M-512 Dripless Shaft Seal utilizes a mechanical face seal with a stainless-steel rotor and a stationary carbon flange to ensure reliable sealing in marine applications. The rotor compresses the bellow, maintaining consistent contact for compensation of propeller thrust movement. Designed to float around the shaft, the carbon flange addresses misalignment and vibrations, while recessed O-rings on the rotor minimize wear during operation.

PSS 02-115M-512 - Dripless Shaft Seal 115 mm, 5 1/2" Stern Tube

The PSS 02-115M-512 Dripless Shaft Seal is designed for optimal performance in marine applications. Its innovative mechanical face seal technology ensures reliable sealing, even in challenging conditions.

The Type B PSS Shaft Seal features a unique sealing surface formed between the smooth flat surfaces of a rotating stainless-steel rotor and a stationary carbon flange. The carbon flange is securely fastened to the bellow's front side using hose clamps, while the bellow's back end fits over the stern tube, also secured by hose clamps. The stainless-steel rotor is mounted on the shaft at the front of the carbon flange, compressing the bellow before being locked in place with set screws. This compression maintains consistent contact between the rotor and the flange, allowing the seal to adapt to any fore-and-aft movement caused by propeller thrust.

The carbon flange is designed to be slightly larger than the shaft diameter, enabling it to "float" and effectively compensate for misalignments and vibrations. Additionally, the stainless-steel rotor is equipped with two O-rings that are recessed into the collar's bore. These O-rings rotate with the shaft and rotor, ensuring minimal wear and long-lasting performance during operation.
