Mechanical seal “DYNAMICA” model DS-CRH12/16 is widely used for GRUNDFOS-PUMP. Balanced, cartridge O-ring seal unit with rigid torque transmission system. This seal type is assembled in a cartridge unit which makes replacement safe and easy. The balancing makes this O-ring seal type suitable for high-pressure applications.

The normal material combination include SiC/SiC/Viton/machined SUS.304 and TC/TC/Viton/machined SUS.304. We also can make changes as customers’requirement or totally design a new type of mechanical seal to meet clients’ needs.
