Shaft Seals

The “Take-Apart” GITS shaft seal was specifically designed to offer ease in assembly and field maintenance without any modification to existing equipment. The design permits easy component replacement, such as o-ring or spring, if necessary. This feature practically eliminates the need to replace the entire seal if one component shows wear. The “Take-Apart” design promotes the concept that special materials for o-rings and mating rings can be substituted for standard materials upon request.

Construction: The standard materials of construction are a carbon seal nose; NiResist mating ring; and Buna-N O-rings and gaskets. All metal hardware is stainless steel.

Capabilities: Gits seals are designed for effective oil and lubricant retention over long periods of time under rugged conditions. Our standard units operate at 0 to 10 psi; 10° to 250° F temperature and up to 3000 FPM speed at seal face.
