M Series Mixer Seal

Flowserve M Series top-entry mixer seals are designed to perform consistently and in a variety of applications, providing more possibilities than ever before in a single cartridge.

It can be difficult to seal mixing instruments. When selecting the appropriate seal, consider a variety of considerations, including product contamination, high pressures, shaft run-out, space constraints and emission control.

This mixer cartridge canister seals are designed to accommodate today’s demanding operating conditions and will satisfy tomorrow’s needs for increased shaft size, temperature, pressure and speed applications.

M Series Mixer Seal Application

Benefit

Standardized seal designs allow seal cases, sleeves, and glands to be interchanged for use with technologies that use liquid lubrication, dry running or full fluid-film faces.
It operates at 0 rpm thanks to non-contacting gas barrier technology.
Allows for radial run-out of up to 3.2 mm (0.126 in.). Total indicator reading (TIR) eliminates the need for a bearing in the housing and allows for smaller shaft sizes at a lower cost.
Standard shaft-centered seal housings eliminate the necessity for accurate radial alignment (concentricity) of the shaft-to-flange hole.
Economical high-alloy choices outperform in tough, corrosive situations.
A sanitary gland with a waste well is provided for steam cleaning applications.
MD and MW designs feature pressure-reversal capabilities for greater seal integrity under off-design operation.
