A simple, proven and rugged design with dependability that has made it a favorite choice of maintenance personnel to seal ANSI chemical pumps. Heavy cross sections of the rotary components resist high levels of corrosion. Utilizing a simple rugged open rotary unit design, aggressive, abrasive and viscous fluids can be sealed easier than with other ANSI seal types that incorporate shrouded spring rotaries.

-
FEATURES & BENEFITS
- Open rotating compression unit imparts a turbulent flow of the process fluid which helps keep solids away from the seal faces and removes
- seal generated heat. The flexibly mounted insert compensates for misalignment to ensure seal face contact. Off-the-shelf availability in standard configurations for most chemical pumps.
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.
