Designed to fit in housing bores that meet ANSI and DIN 24960, these seals have an extended spring that accommodates variations in seal cavity length. They're used in waste water, boiler feed, and compressor pumps. Seals come furnished as two pieces—the seal and the seat. The seal is comprised of the case, spring, diaphragm, and washer, which come locked together as one piece. The seat is comprised of the seat and the gasket.

Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Commonly used in well, sump, and displacement pumps, these seals have a two-piece spring-loaded design that keeps the sealing surfaces in contact as the material wears. Seals come furnished as two pieces—the seal and the seat. The seal is comprised of the case, spring, diaphragm, and washer, which come locked together as one piece. The seat is comprised of the seat and the gasket.

Buna-N diaphragms and gaskets resist grease and a wide range of oils.

Viton® fluoroelastomer diaphragms and gaskets resist a wider range of chemicals than Buna-N.

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.
