feeding. On total discharge, before the discharge takes place, there is the closure of feeding
valve with interruption of the product feeding (controlled by the PLC) and the stop of feeding
pump.
The ejected sediments are collected into an outer anular chamber where they are drained away
by gravity through a pipe.
Bowl feeding is carried out through a closed pipe line with outlets of the product under
pressure, by means of two centripetal pumps and without seal gaskets between fixed parts and
rotating parts. On inlet-outlet pipe lines are inserted valves and instrumentation necessary to
control and regulate the separator (micrometric adjusting valves, butterfly valves, sanitary
pressure gauge, sample cocks, etc.).
The electric control panel is equipped with a mimic with optical signals of the separator
working main phases and an ammeter which indicates motor current absorption.
