Danfoss 071N0173 BFP21R5 gear pump technical data: Viscosity range (in the suction line): 1.8-12.0 cSt(mm2/s) Filter area / cross-section: 11/200 cm2/microns Pressure range: 7-20 bar Factory settings: 10 ±1 bar Max. pressure in the suction/return line: 2 bar Shaft rotation speed: 1400-3450 min Max. starting torque: 0.12 Nm Ambient temperature: -20 to +70 °C Storage temperature: -25 to +120 °C Fuel temperature: 0 to +70 °C Coil protection degree: IP40 Shaft: EN225 Danfoss BFP21R5 071N0173 oil pump adjustment: From the suction line, through the filter, the fuel enters the gear mechanism, which increases its pressure. When voltage is applied to the NC valve (normally closed), it opens and fuel is supplied to the nozzle line. Thanks to the diaphragm of the regulator, the pressure is maintained constant and equal to the setting value. In 2-pipe mode, excess fuel is returned to the tank via the return line. In single-tube mode, the return line is closed and the screw is missing. Excess fuel is sent to the bypass line.
