Mechanical Shaft Seals
Profile
Commonly used in mixing and grinding equipment, conveyors, and construction machinery, these seals withstand exposure to abrasive material. Their metal-to-metal sealing surface provides durability for long-term service in heavily contaminated environments. Seals have two highly-polished iron rings secured by diamond-shaped O-rings that make a tight seal against the housing.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
