3.1.3 Fuel pump with solenoid valve
The fuel pump is responsible for fuel supply.
The pump is driven by the burner motor via a coupling.
Fuel is compressed in the fuel pump and atomized by the
fuel nozzle.
The solenoid valve installed at the fuel pump opens and
closes the fuel supply to the fuel nozzle.
Depending on the heating capacity class and the opera-
ting voltage, different fuel pumps are installed in the
heaters.

It is a high-pressure atomizing nozzle with filter element.
Each heating capacity class is a different fuel nozzle
assigned..
