Suntec A2L Pumps
The Suntec A2L Series of pump are a light oil pump designed for use on a 1 or 2 pipe system. Suntec A2L pumps have two built in solenoids allowing for a dual nozzle supply with independent cut-off functionality. A single regulator delivers the same pressure to both nozzles
Cut-off Solenoids
The solenoid valves of the A2L pump are of the "normally closed" type. Each solenoid valve is situated in one nozzle line. This design ensures extremely fast response and the switching can be selected according to the burner operating sequence and is independent of motor speed. When the solenoids are non-activated, the valves are closed and all oil pressurised by the gear set passes through the regulator to the suction or to the return line, depending upon pipe arrangement. As soon as the solenoids are activated, oil passes to the nozzle lines at the pressure set by the pressure regulating valve.
The two solenoid valves can be operated independently.
Rotation
Rotation of these pumps is determined by viewing the pump from the shaft end.
Pump Options
If the Part number has a K at the end, it is suitable for use with Kerosene.
