Mixer Mechanical Seals

Top entry mixers and bottom entry agitators on sealed tanks will have some sort of mechanical seal.  For many sanitary process vessels, the mixer must have some type of sealing barrier to providing either a dust-tight vapor seal, a pressure-tight seal to allow pressure or vacuum in the mix tank, or an aseptic sealing device to provide a hygienic seal between the tank id and the outside of the vessel.  There is a variety for mixer use, including single dry running double assemblies with a liquid or gas flush, and a variety of other lip seals and packing materials that can be used.  Starting with the least expensive sealing mechanism for a rotating mixer or reactor, we have a simple dust cover assembly and elastomer lips seal, a spring-loaded CIP mixer seal, a packing seal, a USP class VI lip seal, a single dry running mixer seal, a single with an aseptic debris well and higher pressure double, custom steam sterilizable and split options.
