Pump's pressure / Oil temperature
diagram
The gasification of volatile fractions in pre-
heated 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 herei-
nafter.

pressure connection
The heavy oil burner pump used is a self-
priming gear pump, which must be
connected as two-line pump via a bleed
filter. There is an intake filter and an oil
pressure regulator integrated in the pump.
Pressure gauges for pressure
measurements and negative pressure
measurements must be connected before
the equipment is commissioned.
NB: before starting the burner, check that
the return pipe is open. An eventual
obstraction could damage the pump
sealing device.
