The Original Dripless Shaft Seal System
PSS (Packless Sealing System) dripless shaft seals provide maintenance-free, leak-free operation with a proven track record spanning decades. The industry standard for reliable shaft sealing across all vessel types.
Innovative bellows design provides maintenance-free, dripless operation
Flexible stainless steel bellows attached to the shaft rotates with it while remaining sealed to the stern tube.
Small amount of water enters the bellows area for lubrication, preventing dry running and wear.
Automatically adjusts to shaft movement and wear, maintaining perfect seal without any intervention.
Unlike traditional packing glands that require regular adjustment and allow controlled leakage, PSS seals are completely dripless and require zero maintenance once properly installed.
Bilge stays completely dry
Set it and forget it operation
Self-lubricating design
Years of reliable operation
Superior performance and reliability for all vessel types
Complete dripless operation keeps your bilge completely dry, eliminating pump cycling and reducing corrosion concerns.
Automatically compensates for shaft wear and movement, maintaining optimal sealing without any adjustment required.
Once installed, requires no maintenance, adjustments, or servicing for years of reliable operation.
Uses shaft rotation and natural water ingress for lubrication - no external water injection system required.
