Mechanical seal R-58U/59U
Mechanical seal R-58U/59U
The single mechanical seal of the R-59U/R-58U series is multi-spring, unbalanced, does not depend on the direction of rotation of the shaft. Thanks to a set of small springs, the loads in the friction pairs are distributed evenly. Modification of the R-59U using secondary wedge seals made of PTFE allows the seal to be applied in extremely aggressive corrosive environments. It is often used as a component of a double seal. Complies with EN 12756, DIN 24960, ISO 3069 and API 610 specifications.
Application: Thune Eureka, KSB, HM, AH, HMS, VK, ONL, VKS, ONC, etc. centrifugal pumps, mixers, agitators of chemical, petrochemical, gas and pharmaceutical industries.
