Mixer Seals - M Series

About this product

M Series 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. The M Series platform allows you to adapt the vertical shaft mixer seal to changing production requirements without investing in an entirely different seal. The seal faces can be changed out to run wet, dry contacting, or dry non-contacting gas barrier technology. With unprecedented application flexibility within one cartridge, the M Series design reduces the number of components in inventory and provides interchangeable parts across the product line for true component standardization.

Features and Benefits

Standardized seal designs permit interchangeability of seal housing, sleeves and glands for applications in liquidlubricated, dry-running or full fluid-film face technologies.
Non-contacting gas barrier technology enables operation at 0 rpm.
Tolerates radial run-out of up to 3.2 mm (0.126 in.) total indicator reading (TIR); eliminates bearing from the housing and permits reduced shaft diameters for lower cost.
Standard shaft-centered seal housings reduce the need for critical shaft-to-flange bore radial alignment (concentricity).
Economical high-alloy options provide superior performance in harsh, corrosive environments.
Available sanitary gland with debris well for applications requiring steam cleaning.
Cooling canister seal chamber liner efficiently removes heat in the seal area.
MD and MW designs feature pressure-reversal capabilities for greater seal integrity under off-design operation.
Hydraulically balanced stators reduce high-pressure loading, minimizing seal face distortion and leakage.
RedRaven Ready to be compatible with Flowserve’s condition monitoring hardware.
