SUNTEC
This is a general specification leaflet ; for specific applications not covered
herein, contact Suntec.
The SUNTEC A2L oil pump has two nozzle outlets. It incorporates two blocking
solenoid valves with in-line cut-off function, one for each nozzle outlet.
APPLICATIONS
– Kerosene, light oil.
– Two nozzle outlets.
– Two independant blocking solenoid valves.
– A sole regulator for both nozzle lines.
PUMP OPERATING PRINCIPLE
The gear set draws oil from the tank through the built-in filter and transfers it to the
nozzle lines via the cut-off solenoid valves . A pressure regulating valve is used to
bypass all oil which is not required at the nozzles.
In two-pipe operation, the by-pass plug must be fitted in the return port, which ensures
that the oil bypassed by the regulating valve is returned to the tank and the suction
line flow is equal to the gear set capacity.
In one-pipe operation (by-pass plug removed and return plugged), the oil which does
not go through the nozzle lines is returned directly to the gear inlet and the suction
line flow is equal to the sum of the 2 nozzle flows.
Bleed
Bleeding in two-pipe operation is automatic : it is assured by a bleed flat on the piston.
In one-pipe operation, the plug of a pressure gauge port must be loosened until the
air is evacuated from the system.
Cut-off
The solenoid valves of the A2L pump are of the “normally closed” type and are situated
in the nozzle lines. This design ensures extremely fast response and the switching
can be selected according to the burner operating sequence and is independant 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 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.
