Type Sever C is a balanced, single-spring, pusher-type single cartridge seal, independent of shaft rotation direction. It is used in general and process industries, as well as oil refining applications. Designed to operate under extremely demanding conditions, its robust seal face and durable composite materials ensure extended service life in high-pressure, high-temperature, and abrasive environments. The single-coil spring design enables a soft start and prevents the blockage of moving parts. Available with or without an integrated pumping ring.
