Its designed functions are the same as M7 series. Except for the installation dimensions
of drive base, the other installation dimensions (d1<100mm) are subject to DIN24960.
It is suitable for medium that contain fiber or solids which can easily solidify.
The mechanical seal range is designed for universal application and the interchangeable
parts concept is ideal forthrust ring is retained by the drive lugs preve stock rationalization.
The seal faces are loosely inserted and can be easily exchanged, the nting the spring
falling out.Other special technical features include stationary seal stop and limitatlion
of spring stroke to prevent excessive carbon wear.
