Watson Marine Engineering Shaft Seals

PSS Shaft Seals

The PSS shaft seal eliminates all the problems of the old style stuffing box by using a concept employed on military vessels and thousands of European yachts for years with perfect reliability.

The PSS system gives you a NO Maintenance, NO Drip answer to your stuffing box problems.

The PSS Shaft Seal offers many Advantages over the old style stuffing box: 100% Watertight NO Maintenance Required Very Easy Installation Prefect Reliability Prevents Shaft Wear Self Aligning Vibration & Noise Free Low Friction

How the PSS system works:

The reinforced rubber bellow is secured at one end to the shaft log and at the other to a high density carbon flange. The bellows, and the water pressure, force the carbon flange against a polished stainless steel rotor which is mounted on the shaft and secured in place by a pair of double set screws. Two O-Rings are used to prevent water from leaking between the shaft and the stainless steel rotor. When the shaft rotates, the stainless steel rotor turns against the carbon flange; the high polished carbon reduces friction to a minimum and eliminates any possibility of leakage.

Deep Sea Seals

Worn shafts, leaking glands and continuous maintenance are a thing of the past. The simple design of the Deep Seal Seals provides a maximum selling capacity for use on all types of vessels.

The incorporation of high resistance interface materials together with a design to minimise galvanic corrosion dramatically reduces maintenance costs. Enhanced by a statically mounted elastomeric body, the seal accepts misalignment in all planes and compensates for vibration, which can be inherent on vessels involved in costal trade such as ferries, cargos, fishery vessels, workboats and river craft or when trading in sandy or silty waters.

Features: Fully & partially split design Robust construction Accepts misalignment and vibration High interface abrasion resistance Compact built length Accepts high shaft speed Factory test on all seals Compensates for bearing wear Benefits: Reliability Low installation cost Low through life costs Easy, quick installation Long service intervals Suitable for use in aggressive water conditions
