1.2 Brief description
The Mixerpac 2564 is delivered as a complete, bidirectional and ready-to-install seal-
ing cartridge. It seals the product chamber of a mixer vessel from the atmosphere.
It comprises a multiple mechanical seal (MS) with axially arranged seal ring pairs,
on the product side as well as on the atmospheric side an unbalanced seal, a shaft
sleeve, housings with an integrated self-aligning roller bearing and optional with an
installed cooling flange. The bearing is a floating bearing for the mixer shaft and
undertakes radial guiding tasks only.
1.3 The spring force and the hydraulic barrier pressure push the seal rings against the
mating rings. The seal faces are sealed from the shaft sleeve, respectively from the
housing, by sealing elements (e. g. O-rings). The faces of the seal ring and the mat-
ing ring are designed as sealing faces.
On the product side, the MIXERPAC has a mechanical seal with self-sealing effect
