How PSS Shaft Seals Work

Innovative bellows design provides maintenance-free, dripless operation

1

Bellows Design

Flexible stainless steel bellows attached to the shaft rotates with it while remaining sealed to the stern tube.

2

Water Lubrication

Small amount of water enters the bellows area for lubrication, preventing dry running and wear.

3

Self-Adjusting

Automatically adjusts to shaft movement and wear, maintaining perfect seal without any intervention.

Why PSS is Different

Unlike traditional packing glands that require regular adjustment and allow controlled leakage, PSS seals are completely dripless and require zero maintenance once properly installed.

No Dripping

Bilge stays completely dry

No Adjustments

Set it and forget it operation

No External Water

Self-lubricating design

Long Service Life

Years of reliable operation

PSS Shaft Seal Benefits

Superior performance and reliability for all vessel types

Zero Water Ingress

Complete dripless operation keeps your bilge completely dry, eliminating pump cycling and reducing corrosion concerns.

Self-Adjusting Design

Automatically compensates for shaft wear and movement, maintaining optimal sealing without any adjustment required.

Maintenance-Free

Once installed, requires no maintenance, adjustments, or servicing for years of reliable operation.

No External Water

Uses shaft rotation and natural water ingress for lubrication - no external water injection system required.
