BRAND: Durametallic
A single balanced seal designed to mount outside the seal chamber. No wetted metal parts (RA-C) reduce seal costs for highly corrosive services, especially on non-metallic pumps. Installs easily on the outside of the seal chamber and is suitable for metallic and nonmetallic equipment such as plastic, glass, and lined designs.

- Seal faces and elastomers are the only wetted components and are readily available in a wide range of materials for proper corrosion resistance.
- RA seal uses a composite rotor with an economical seal face insert. RA-C seal uses a solid ceramic rotor with a protective PTFE shroud.
- Drive collar, springs, and drive pins are isolated from the product to avoid the need for expensive alloys in highly corrosive services.
