The SUNTEC AN oil pump is the basic model incorporating a pressure regulating valve. It does not have a cut-off feature, this allows purging of air through the nozzle line.

 

APPLICATIONS

- Light oil, B10 heating oil/biofuel blend (as defined in DIN V51603-6) and kerosene.
- One or two-pipe system.
- Pressure regulator and hydraulic cut-off function.

 

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.

 

Bleed:

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.
