WARNING: For a correct working of the pump, verify what follows:
Pump :
Oil temperature at the pump:
Maximum allowable pressures:
The gasification of volatile fractions in preheated
heavy oil seems to be the main cause of premature
fuel pump wear. To avoid such a problem, adjust
pump pressure according to the diagram hereinafter.
SUNTEC E
VERIFY:
- That piping system is perfectly sealed;
- That the use of hoses is avoided whenever is possible (use copper pipes preferably);
- That depression is not greater than 0,45 bar, to avoid pump's cavitation;
- That check valve is suitably designed for the duty;
The pump pressure is set at a value of 22-25 bar during the testing of burners. Before starting the burner,
bleed the air in the pump through the gauge port. Fill the piping with light-oil to facilitate the pump priming.
Start the burner and check the pump feeding pressure. In case the pump priming does not take place during
the first prepurging, with a consequent, subsequent lock-out of the burner, rearm the burner's lock-out to
restart, by pushing the button on the control box. If, after a successful pump priming, the burner locks-out
after the prepurging, due to a fuel pressure drop in the pump, rearm the burner's lock-out to restart the
burner. Do never allow the pump working without oil for more than three minutes.
Note: before starting the burner, check that the return pipe is open. An eventual obstruction could damage the
pump sealing device.
