Suntec AS Pumps
The Suntec AS Series of pump are a light oil pump designed for use on a 1 or 2 pipe system. Suntec AS pumps have a built in solenoid valve which controls the regulator cut-off valve giving fast cut-off and cut-on function independent of the rotational speed.
When the burner stops, the solenoid opens the by-pass at the same time, which drains all the oil down to the return, and the nozzle valve closes immediately. This gives a very sharp cut-off function. The cut-on and cut-off can be actuated regardless of motor speed and have an extremely fast response. When the solenoid is not activated, the torque requirement is low up to full motor speed.
Rotation of these pumps is determined by viewing the pump from the shaft end.
If the Part number has a K at the end, it is suitable for use with Kerosene.
If the Part Number has a V in, it is fitted with Viton Seals.
