Mechanical seal R-58B/59B

Mechanical seal R-58B/59B

The single mechanical seal of the R-59B/R-58B – jest wieloprężne, zrównoważone, niezależne od kierunku obrotu wału. Obciążenia w parach ciernych są równomiernie rozłożone dzięki zestawowi małych sprężyn. Modyfikacja R-59B za pomocą wtórnych uszczelnień klinowych z PTFE pozwala na zastosowanie uszczelnienia w wyjątkowo korozyjnych środowiskach. Często stosowany jako element podwójnego uszczelnienia. Zgodny z normami EN 12756, DIN 24960, ISO 3069 i API 610.

Application: KSB, XM, etc. centrifugal pumps, mixers, agitators of chemical, petrochemical, gas industry.
