Danfoss 071N2204 BFP52E R5 pompa dell'olio

Danfoss BFP52ER5 071N2204 oil burner pumps used in small and medium-sized 2-level household burners with fuel consumption up to 42 l/h. Fuel passes through the filter to the gear mechanism, increasing pressure. The regulator maintains constant pressure. The NC valve opens fuel supply to the nozzle, while the NO valve disables the regulator when activated. In two-pipe mode, excess fuel returns to the tank; in one-pipe mode, it goes to the bypass. When the burner stops, both valves close, stopping fuel flow. In two-pipe mode, no purge is required; in one-pipe mode, purging is done via the nozzle or pressure gauge ports.
