PYI's PSS Shaft Seal is designed for industrial pump applications
The PSS Shaft Seal is a dripless mechanical face seal that’s created between a rotating stainless steel rotor and a stationary carbon stator. 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 float design and flexibility of the PSS Shaft Seal allow for substantial axial movement of the shaft while still operating correctly.
Minimal maintenance is required under normal working conditions with replacement parts readily available. Unlike other sealing systems, the PSS Shaft Seal does not wear the shaft or surrounding materials during operation which results in longer maintenance intervals.
