Oil Motor Pump type BFPM 61
Application |
The BFPM range is a series of Danfoss oil pumps in |
BFPM 61 features: |
|
|
combination with a highly efficient permanent |
• Light oil and kerosene |
|
|
magnet motor. |
• |
1- or 2-pipe operation |
|
The BFPM Electronic Controller must be used for |
• |
1-stage modulating |
|
controlling BFPM motor pumps (see separate data |
• |
Built-in pressure regulator |
|
sheet for BFPM Electronic Controller). |
• |
Solenoid valve cut-off |
|
|
• |
Cartridge filter |
|
BFPM 61 is designed with a pressure transducer, |
• |
Pressure transducer |
|
which makes it ideal for small, modulating oil |
• Variable set points and up to 3 set-back periods |
|
|
burners. |

Pressure |
Suction |
Return |
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, it opens and releases oil to the nozzle outlet.
The pressure transducer (PT) reports the achieved pressure and the control, in conjunction with the oil/air ratio control, regulates the motor speed.
The built-in pressure regulator prevents overpressure. Default setting is 30 bar.
Cut-off function, solenoid valve
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.
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).
