Fuel oil pressure unit with integrated bypass oil air separation for single-pipe oil supply for automatic oil burners to TRD 411 or TRD 604 and DIN 4755 sheet 2.
As most units of the MOG 19… series have to be engineered according to the burner power, we recommend fine-tuning with the manufacturer.

Functional description: Design according to Scheme A (with supply pressure on T connection)
The pump (6) is supplied with oil via ball valve (1), filter (2), manometer (4), vessel (5) in single-pipe system, i.e. only the oil consumed by the burner flows here.
For manual ventilation, the supply pressure must be at least 1 and max. 5 bar. For automatic float air vent (accessories 17) the supply pressure must be max. 5 bar. A higher supply pressure must be reduced with pressure-regulator (accessories 18). Further accessories are adapters for oil meters (15), oil meter (16), solenoid valve (20), leakage detector (19) and filter indicator (21 + 22).
The pump (6) increases the supply pressure to the operating pressure that can be set on the overflow valve, that the pressure gauge (7) displays and supplies the pressurised oil to the burner via the ball valve (11). Return oil coming from the burner is fed back via the ball valve (11) to the vessel (5) and therefore the pump (6). If there is no oil consumption, the entire oil supplied by the pump is controlled via the overflow valve to the vessel (5) and therefore the inlet side of the pump (6).
Scope of supply:
1 Ball valve PN 16
2 Filter PN 6
4 Vacuum gauge with gauge valve
5 Vessel with manual ventilation
6 hp-Motor pump group consisting of:
hp-Internal gear pump with integrated overflow valve and bypass connection, pump connector, coupling and standard motor
7 Pressure gauge with gauge valve
11 Double ball valve PN 40
14 Oil pan
Other designs (e.g. for suction operation or accessories) on request.
Accessories:
15 Adapter for oil meter installation
16 Oil meter
17 Automatic float air vent
18 Pressure regulator
19 Leakage detector
20 Solenoid valve
21 Optical filter indicator
22 Optical and electrical filter indicator

* To ensure the pump is working properly, the pipes must be scaled according to the principles of fluid dynamics by calculation of line according to the local requirements.
The pump or device connection gives no indication of the relevant size of the pipe.
