Nozzle Port: Left
Shaft Diameter: 8mm
The SUNTEC AS oil pump has 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.
- Light oil, B10 heating oil/biofuel blend (as defined in DIN V51603-6) and kerosene.
- One or two-pipe system.
- Pump with pressure regulator and cut-off function controlled by an integral solenoid valve.
PUMP OPERATING PRINCIPLE
The gear set draws oil from the tank through the built-in filter and transfers it to the valve that regulates the oil pressure to the nozzle line.
All oil which does not go through the nozzle line will be by-passed through the valve back to the return line, in a two pipe installation or, if it is a one-pipe installation, back to the suction port in the gear-set. In that case the by-pass plug must be removed from the return port and the return port sealed by steel plug and washer.
Bleeding in two pipe operation is automatic.
In one pipe operation, a pressure port must be opened to bleed the system.
For the first start up, bleeding can be accelerated by loosening the plug in a pressure gauge port.
