Description
The Suntec AE V 67 C 7307 4P burner pump pumps diesel fuel at a pressure of 8-28 bar. It is a basic model with a pressure regulating valve without a locking function. Air is vented through the nozzle line. A solenoid shut-off valve is installed additionally. The pump's performance depends on the fuel viscosity, ambient temperature, and pressure.
Device and features
The pump is assembled for a two-pipe system. A bypass plug is installed in the return line hole. When installing in a single-pipe installation, it is necessary to block the fuel return channel by replacing the bypass plug with a steel one with a washer. A manual regulator is provided for adjusting the operating pressure.
Fuel is pumped from the tank to the burner by a gear working mechanism. When the gear pair rotates, the working fluid is sucked in and passes through a built-in filter with a working area of 6 cm², to the pressure regulating valve and then to the nozzle. Excess fuel is sent to the return line in a two-pipe connection, or to the suction line in single-pipe systems.
Air venting in systems with a return line is automatic, in single-pipe systems – through the bypass hole of the nozzle line coupling.
This model does not have a locking function. It is provided by an external solenoid valve.
Characteristics and features:
- pressure adjustment in the range of 8-28 bar, default – 14 bar;
- use in systems with an external solenoid valve;
- mesh filter at the inlet to remove solid particles of 150 microns or more;
- design for single-pipe and two-pipe systems (factory assembly with a bypass plug);
- Viton seals;
- rotation counterclockwise / outlet to the nozzle on the left side;
- pressure regulating valve without locking;
- gear working mechanism, resistant to fuel composition and loads;
- installation in any position, except with the axis upwards;
- operating temperature range (fuel inside the pump): 0...+60 °C;
- automatic venting of excess air in two-pipe installations;
- permissible fuel viscosity: 2...75 cSt;
- degree of purification of the built-in filter: 150 microns.
Application
Diesel pumps for burners are installed in industrial heating systems designed to heat large production areas. Suitable for liquid fuel burners of most well-known brands.
