Description
The AT3 45 B 9575 4P 0700 liquid fuel pump is manufactured by the French company Suntec and is designed to operate in one of two modes as part of a diesel heating burner. For each of them, you can set the pressure value at which fuel will begin to flow to the injector line. A distinctive feature of the AT3 line is the presence of a port for a pressure gauge measuring the pressure at the second stage.
On the ANKAS company website, you can buy a burner fuel pump at the manufacturer's price. Our managers will consult you and answer all your questions, and also help you choose a model according to the specification.
Design features
The operation of the liquid fuel pump of this model is based on the clockwise rotation of the gear mechanism. The creation of negative pressure in the suction fuel line helps to pump the working fluid from the tank. The fuel passes through a mesh cylindrical filter with an open area of 6 cm², where it is cleaned of mechanical particles, and only then is it pumped through the channels to the spool valves by a toothed pair.
The spool valves act as a pressure limiter. Excess diesel fuel returns through the electromagnetic bypass valve to the drain. Its activation leads to the activation of the high-pressure spool valve, where the return flow occurs in the same way.
The shut-off valve disconnects the pump from the feed line by a signal from the burner control panel, regardless of the rotation speed of the drive shaft.
Advantages of the model:
optimal feed (up to 46 l/h) and high efficiency;
two stages of operation when pumping diesel fuel to the nozzle;
built-in shut-off valve;
ports with cylindrical thread G⅛" for connecting instrumentation devices - pressure gauge and vacuum gauge;
can be installed in a 1-pipe and 2-pipe fuel pipeline system;
maximum pressure on the injector - 2.5 MPa.
Suntec brand products are distinguished by their general concept: they are durable, repairable and unified. The model AT3 45 B 9575 4P 0700 in question is no exception, because its sleeve connection with a diameter of 32 mm is suitable for many burners from famous brands with a capacity of up to 1000 kW. Long service life is calculated in years of intensive work in industrial conditions. All worn parts, assemblies and gaskets can be replaced with new ones from the manufacturer.
