The Blank End Plug (BEP) is installed within the permeate tube of the first membrane within the housing. Its primary function is to seal the permeate tube from incoming feed material, ensuring correct flow paths and maintaining system performance.
Unlike an ATD, the BEP does not need to account for telescoping forces at the feed end. Its simplified design allows for maximum flow to into the element feed channels and onto the membrane surface, supporting efficient production and effective cleaning (CIP).
Yes, a BEP is all that is required for most horizontal membrane vessel configurations. The purpose of the Blank End Plug is to simply seal the permeate tube from the feed material. The Blank End Plug is not shaped like an ATD as there are no telescoping forces on the feed end of the membrane.
SMS EPDM and VITON lip seals are designed to fit global membrane permeate tube internal diameter dimensions standards. SMS have designed its own combination of ATD and Lip seal to meet these global standards. Depending on what OEM membrane component end users have in their plants there may be some subtle differences when SMS lip seals are applied to non SMS components. Providing shipping is covered, SMS can send samples to you to ensure seal fit meets your needs.
