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.
