Compensates For Misalignment

The carbon stator is bored larger than the shaft diameter, allowing it to "float" around the shaft and compensate for most misalignment and vibration problems.

Dripless

Unlike traditional stuffing boxes the PSS mechanical seal is completely dripless.

Why PSS ?

Flexible Design: In addition to carrying standard sizing, a major advantage of the PSS Shaft Seal is its ability to be customized to adapt to an existing installation or design. Because of the ability to design the seal to fit most existing systems, engineers are unconstrained by seal size requirements. The time frame for custom seals is usually very low, 3 to 4 weeks.

Reliable & Durable: Due to its simple design the PSS Shaft Seal is durable and reliable, with a typical life span of 25,000 running hours. Under clean water conditions the seal can exceed 100,000+ running hours. The unique "float design" & flexibility of the PSS Shaft Seal allows for substantial axial movement of the shaft while still operating correctly.

Low maintenance & Ease of Installation: Minimal maintenance is required under normal working conditions with replacement parts readily available. Unlike other sealing systems, the seal does not wear the shaft or surrounding materials during operation which results in longer maintenance intervals.

Easy Installation

With only a few main components, the PSS seal can be quickly and easily installed minimizing downtime.

Innovative Design

Due to the carbon stator being bored larger than the shaft dieameter, the PSS mechanical seal "floats" around the shaft. This compensates for any misalignment or vibration issues.

Flange & Bladder System

The PSS Flange & Bladder System is available in aluminum, steel and stainless steel.

A large number of installations are manufactured with a multi bolt flange in lieu of a stern tube. Very often these flanges have a standard bolt pattern. In order to facilitate the installation of the PSS Shaft Seals on these type of flanges, PYI manufactures an array of flanges which fit the "standard" bolt patterns and transform the flange into a stern tube ready to accept the PSS Shaft Seal.

These adapters can be ordered as a standard unit or as an inflatable bladder unit. The inflatable bladder option allows the operator to seal the stern tube, while the shaft is not rotating, in order to inspect or clean the seal. Another advantage is that if uncoupling of the shaft is needed, this operation can be done in the water as the shaft can be moved aft with bladder inflated, and no water intrusion will happen. Of course this inflatable bladder can also be used in case of an emergency.

Numerous Materials Available

Available in aluminum, steel or stainless steel.

Multiple Versions

Two units available. A standard unit or a inflatable bladder unit.

Advantages

  • Blank or pre-drilled flange bolt pattern for your specific application
  • Inflatable bladder unit minimizes downtime by allowing you to uncouple the shaft while in the water

How It Works!
For PSS Flange Systems with a bladder.

When the rubber bladder is deflated it allows water to flow through.

Once the bladder is inflated it prevents the water from entering into the PSS seal.
