OPERATOR’S MANUAL
ABRASIVE (ABR)
Purge ports located in both end plates
provide continuous positive pressure to the
bearing cavity, preventing product buildup
in the bearing and seal area. This feature
is used when conveying abrasive materials
or powders to prevent premature wear and
damage.
HARD COATING (HC)
A hard coating is applied to the interior
machined surfaces of the casing and/or
end plates, providing improved wear
resistance.
HALAR COATING (HALAR)
Alternative coatings may be applied to the
interior machined surfaces of the casing,
end plates, and/or rotor blades and shaft.
These coatings provide corrosion and
abrasion
protection as well as a
low-friction surface to prevent hang-up of
oily products.
