Function
- Oil burner pump
SUNTEC E
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
