All Greerco colloid m ills utilize co mmonly accepted elastomeric materials
for the seals and o-rings. The co
mmon construction materials are listed
below. Shoul d the products you are pr ocessing require alte rnate materials,
we would be happy to source these components for you.
Shaft Seals
See above section detailing shaft sealing options.
Should your seal leak, you will see process material discharge from the weep
hole located in the underside of the mill housing.
Seals should be replaced at the first sign of leakage or more costly
failures may result.
O-Rings
Your colloid m ill is equipped with fi ve (5) o-ring gaskets. All o-rings
supplied by the factory are Viton
®
, unless alternate materials were requested
at the time of quote. There are three (3) wetted o-rings; seal plate, stator OD
and stator face. The o-rings that are not wetted are the duplex bearing o-ring
and radial bearing o-ring.
