Description

The A2L 65 D 9705 4P 0700 gear pump from the French company Suntec is designed to pump a large volume of fuel (81 l/h) under high pressure in two directions at once. Each injector line can operate independently of the other thanks to shut-off electromagnetic valves. The set pressure is maintained by a spool pressure reducing valve with an adjusting screw.

The ANKAS company website offers to buy a heating burner pump at an affordable price. To order equipment, contact the manager by phone or fill out a short feedback form.

Design features

  • All the hard work of moving fuel to the injectors is performed by the gear mechanism. It includes a gear pair: a straight-toothed gear and a wheel. Their mutual counterclockwise rotation causes a vacuum in the suction pipe. The entrained fuel is pushed into the high-pressure channel, and then to the injectors.

  • The pump controls include electromagnetic solenoids and a slide valve. The former are responsible for the order of switching on the feed and locking the channel by a signal from the burner control unit. The latter acts as a pressure level regulator in the range from 8 to 15 bar. The adjustment process does not require stopping the drive rotation, which makes it more comfortable and faster.

Model advantages:

  • high-performance model for supplying different grades of diesel fuel;

  • each outlet to the injectors operates independently;

  • wide adjustment range — from 8 to 15 bar;

  • excess fuel discharge through an additional pipe into the tank (two-pipe system);

  • inlet and outlet threads comply with the European standard ISO 228/1;

  • unified sleeve connection with the burner with a landing diameter of 32 mm;

  • there is a built-in fuel filter that retains mechanical particles from 150 microns and more.

Suntec devices are designed to increase the convenience of assembling the entire fuel system. Model A2L 65 D 9705 4P 0700 is a multifunctional pump, in which all the main elements are installed: electromagnetic valves, pressure reducing valve, ports for instrumentation, mesh filter. Their compact placement in the device body gives an aesthetic appearance and significantly reduces the dimensions of the assembly.
