Mechanical seal R-502B. Page 2
Mechanical seal R-502B
The mechanical seal R-502B is single, with an arbitrary direction of rotation. An efficient design with a closed siphon, a reliable drive and a central spring ensures long service even with increased pressure and shaft backlash.
Application: for centrifugal pumps, compressors, etc. in the petrochemical, food industries, in public utilities. Pumps of such brands: KOLMEKS, Hydro-Vacuum S.A., WILO, etc.
