The PSS 02-25M-114 Dripless Shaft Seal is a mechanical face seal that ensures a reliable and tight seal between a rotating stainless-steel rotor and a stationary carbon flange. It maintains consistent contact through pre-load compression, compensating for shaft movement and misalignment. Designed with O-rings that rotate with the shaft to minimize wear, it handles temperatures from 5°F to 225°F, pressures up to 15 PSI, and shaft speeds up to 10,000 RPM.

PSS 02-25M-114 - Dripless Shaft Seal 25 mm, 1 1/4" Stern Tube

The PSS 02-25M-114 Dripless Shaft Seal is a high-quality mechanical face seal designed for reliable performance. It features a stainless-steel rotor and a stationary carbon flange that create a tight seal between the rotating and stationary parts. The innovative design ensures consistent contact between the sealing surfaces, compensating for shaft movement and misalignment due to propeller thrust.
- Type: Mechanical face seal
- Sealing Surface: Stainless-steel rotor and stationary carbon flange
- Attachment: Carbon flange attached to the bellows with hose clamps; bellows secured to the Stern tube
- Pre-load Compression: Maintains constant contact between rotor and flange
- Misalignment Compensation: Carbon flange “floats” around the shaft
- O-Rings: Two O-rings seal the rotor to the shaft, rotating with it and ensuring minimal wear
