BR
Mechanical Seal with rotating seal, stationary multiple springs

Mechanical Seals of the BR series are special-purpose seals for use in media containing solids without external flushing or product circulation. Key features are a rotating seal positioned immediately next to the pump impeller, an open seal chamber facing the impeller, and a spring protection sleeve which has proven to be effective in actual service. BR mechanical seals find application mainly in the scrubbing sections of power station flue gas desulphurization systems, and they are also used successfully in the paper industry.
