Mechanical seal R-109B/R-8B
Mechanical seal R-109B/8B
Multi-spring mechanical seal R-109B/8B - does not depend on the direction of rotation of the shaft, it is easy to install and adjust with the help of mounting screws. A set of small springs ensures uniform load in the friction pair. Mechanical seals R-109B/8B are often used as an element of a double or tandem seal.
The R-109B type, thanks to the use of PTFE-based sealing wedges, is used in particularly difficult working conditions. Complies with API610 standards.
Application: Howden Compressors Limited, PEA, Grundfos TP, Afton, KSB, XM, etc. centrifugal pumps, mixers, agitators for the chemical, petrochemical, and food industries.
