Oil Pump Type BFP 10/11, sizes 8 &

Data Sheet
Oil Pump Type BFP 10/11, sizes 8 & 12
Application
BFP 10/11 features:
• Light oil and kerosene
• 1 or 2-pipe operation
• 1-stage
• Built-in pressure regulator
• Solenoid valve cut-off (BFP 11)
• Ring filter
BFP 10/11 sizes 8 and 12 oil pumps are designed
for medium/large-sized domestic oil burners up
to 120 l/h.
Function
Pressure
Suction
From the suction inlet (S) oil is drawn through the
filter (H) to the gear set, where the pressure is
increased. When voltage is applied to the NC-valve
(normally closed), it opens and releases oil to the
nozzle outlet.
By means of the diaphragm (D) in the pressure
regulator (T) the pressure is kept constant at the
value set on adjustment screw (P1).
In 2-pipe systems the excess oil is led back to the
return outlet (R) and the tank. In 1-pipe systems
with plugged return outlet (R) and a bypass
washer (horseshoe) mounted on screw (A), the oil
is returned internally to the gear set (see figure).
Cut-off function, solenoid valve (BFP 11)
When the burner stops, the voltage to the
NC-valve is cut off and the oil flow to the nozzle
outlet is cut off immediately.
BFP 10 has no solenoid valve. In systems using
this pump, a separate cut-off valve must be fitted
in the nozzle line.

Return
Bleeding
In 2-pipe systems the pump is self-priming, i.e.
bleeding is performed via the constriction (O) to
the return outlet (R).
In 1-pipe systems with plugged return outlet (R),
bleeding must be performed through the nozzle
outlet (E) or the pressure gauge port (P).
Warranty
For pumps used outside the stated technical data
and used with oil containing abrasive particles
Danfoss cannot give any warranty.
Note! The solenoid valve must be replaced after
250.000 operations or 10 years (approved life
expectancy).
