Burner Pump Suntec J 4 NCK 1001 8P

The Suntec J 4 NCK 1001 8P burner pump is used to pump fuel with a viscosity of up to 75 cSt: fuel oil, biodiesel fuel mixture B10, diesel fuel, kerosene when operating industrial boilers. It shows high performance, which depends on the discharge pressure and viscosity of the fuel (177 l / h at 20 bar and 20 cSt).

The Suntec J pump is used:

• in single-pipe and two-pipe installations;

• for pumping medium-viscosity fuel;

• mainly in systems with an external electromagnetic valve.

Operating principle

The gear mechanism is responsible for sucking fuel from the tank and feeding it to the pressure regulating valve, and then to the injector line. The fuel is pre-cleaned from rust particles, debris, sand by a built-in filter, which prevents damage to the working unit. Fuel that does not pass to the injector is drained into the return line if the pump is installed in a two-pipe system, or returned to the suction line in a single-pipe layout. In this case, the bypass plug must first be unscrewed and the hole must be closed with a steel plug.

Features and benefits:

• universal application;

• high reliability and wear resistance;

• external solenoid valve;

• built-in pressure regulating valve with shut-off function;

• fuel supply under pressure of 10-21 bar, factory setting - 12 bar;

• for fuel with a temperature of up to +90 °C;

• flange connection, diameter 54 mm;

• performance - 177 l/h at a viscosity of 20 cSt and a pressure of 20 bar;

• flow filtration by a built-in filter, purification degree 550 μm;

• pipe thread for connection to the suction, return line;

• outlets for a pressure gauge and a vacuum gauge;

• any installation position that eliminates axle load;

• automatic air bleeding in two-pipe systems;

• pressure in the fuel suction/drain line – no higher than 1.5 bar.

When using the Suntec J 4 NCK 1001 8P burner pump, it is necessary to periodically remove dirt from the mesh filter.
