Danfoss 071N2207 BFP52K R5 oil pump
Danfoss BFP52KR5 071N2207 oil burners pumps used in two-stage domestic burners with a flow rate of up to 42 l/h. Fuel passes through the filter to the gear mechanism, where pressure is increased and maintained by the regulator. The NC valve opens the 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.
