    Built for small circulation and dispensing pumps, these seals have short springs. The spring-loaded design 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. Seal Width represents the working height, which is the compressed length when installed. 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.
