RA / RA-C

The RA / RA-C is a single balanced seal designed for external mounting on the seal chamber. It is a pusher seal used in applications where pressures exceed 15 psi/1 bar, making it a suitable alternative to the RO seal. The RA-C variant features no wetted metal parts, making it cost-effective for highly corrosive services, especially in non-metallic pumps. The RA version includes a two-piece rotary collar and seal ring unit.
