Fuel pump Suntec AS67B 7449-4

Oil pump Suntec AS 67 B 7449 is equipped with an integrated normally open solenoid valve, which performs a shut-off function and ensures quick stop and restart of fuel supply regardless of motor speed. This solution increases the reliability of burner equipment and provides precise control of the combustion process. The Suntec AS67B7449 pump is designed for diesel fuel and kerosene and can be used in both single-pipe and two-pipe fuel systems. The pump design ensures stable pressure, effective air removal, and safe fuel supply stop when the burner is turned off. Operating principle of the Suntec AS67B 7449 oil pump: The gear pair draws fuel from the tank through an integrated mesh filter and delivers it to the pressure regulation valve, after which fuel goes to the nozzle line. Excess fuel in a two-pipe system is diverted through the valve to the return line, while in a single-pipe system it returns to the suction side.
