The PSS 02-25M-200 Dripless Shaft Seal is a mechanical face seal designed for marine applications. It features a stainless-steel rotor and a stationary carbon flange that work together to create a reliable seal, compensating for shaft movement and misalignment. The seal maintains constant contact between its components through a pre-load compression, while two O-rings ensure durability without wear. It operates effectively within a temperature range of 5°F to 225°F, a pressure limit of 15 PSI, and up to 10,000 RPM. The bellows are made from molded nitrile-PVC for added resilience.
