Cartridge seal R-CARTEX(SN) 53, CAR/SIC, VITON, 304

Cartridge seal R-CARTEX(SN) is a single balanced seal with a connection for flushing. It is a fully mounted unit for use in oil seal chambers of pumps, in particular centrifugal pumps, with an arbitrary direction of rotation. The R-CARTEX(SN) seal is ideal for use in chemical, petrochemical, pharmaceutical, sugar and food, paper industry, beverage production, water supply. A shut-off fluid supply system is required.
