Mechanical seal R-109/R-8U

Mechanical seal R-109/8U

Mechanical seal R-109/8U - unbalanced, multi-spring, does not depend on the direction of rotation of the shaft. Mechanical seals of this series have a compact structure and high resistance to aggressive environments. Thanks to the use of PTFE-based sealing wedges, the R-109 type is used in particularly difficult working conditions. Complies with API610 standards.

Application: Grundfos TP, Afton, KSB, XM, etc.

Type: John Crane 109, 9, 909/8-1, Sterling 290S, Aesseal M01/M01U/M01S/M01SU, Roten 90, Sealol T, Vulcan 1609/1609S.
