Design
The separator comprises a frame consisting of
the frame lower part, the intermediate part and
the frame top part with a frame hood.
The separator bowl (C) is driven by an electric
motor (A) via a flat-belt power transmission
(D) and bowl spindle (B). The motor drive is
equipped with a friction coupling to prevent
overload.
The bowl is of disc type and hydraulically
operated at sludge discharges. The hollow bowl
spindle (B) features an impeller which pumps
closing water from a built-in tank to the operating
system for sludge discharge.
The main inlets and outlets are shown with
their connection numbers in the illustration.
The connections are listed in chapter Technical
Reference where the basic size drawing also
can be found.
