The solid-seal rings maintain their flatness to prevent leaks. In outstanding leakage prevention and perfect interaction of components and high resistant materials, such as Viton O-rings and robust seal rings with a unique tungsten carbide composition, secure high performance and reliable operation.

Seal rings are available in aluminum oxide or reaction-bonded silicon carbide as well. In addition, Active Seal technology is included in selected Griploc seal variants act as a micro pump to prevent liquid from entering into the motor housing. 



Griploc seals are used for both inner and outer sealing. Mounted in the inner position, the seal prevents liquid from entering the motor housing. Mounted in the outer position, the seal prevents leaks of the pumped media into the buffer chamber.
