Flow Pump FPE
If the upline tank is full the valve
VVBE
is closed automatically. If the flow
pump
FPE
is activated
FPA
is also switched on, to allow an unrestricted flow
through the balance chambers.

is permanently switched on to allow a circulation in
both compartments of the upline tank.
VEB
is opened. If the emptying is activated to drain the machine the pumps are
switched on for a short period and

closed.
All balance chamber valves are opened and the outlet flow pump
FPA
works in
main flow with the same speed as the inlet flow pump
