Oil Burner Pumps
Products code: 55481

Description

The Suntec AN 57 D K 1303 6P burner pump allows pumping diesel fuel and kerosene at a rate of 55 and 44 l/h (at a pressure of 11 bar and a viscosity of 5 cSt / 1.8 cSt). Provides a stable supply of fuel to the burner under a given pressure within 7-15 bar. The pressure in the suction and return line should not exceed 2 bar. A special feature of this series is a built-in pressure regulating valve with a shut-off function. The pump is supplied from the factory for a 2-pipe system and can be upgraded for a single-pipe installation.

Features and main parameters:

  • working environment: diesel fuel and kerosene;

  • gear mechanism moving fuel to the nozzle;

  • high reliability of components and assembly;

  • with a valve regulating pressure and blocking the flow;

  • available pressure adjustment range of 7-15 bar;

  • "default" pressure setting - 9 bar;

  • filtration of fuel entering the pump cavity, purification degree 150 μm;

  • sleeve mounting method, ∅ 32 mm;

  • connection to the pipeline on the G¼" thread (suction and return drain line);

  • ⅛ inch holes for control devices: pressure gauge and vacuum gauge;

  • limitation on the temperature of the pumped fuel: 0...+60°C;

  • installation in any position, except with the axis up;

  • for two- or single-pipe fuel pumping systems (for a single-pipe system, it is necessary to replace the bypass plug with a blind one);

automatic air bleeding in systems with a return line.

Application

The Suntec AN 57 D K 1303 6P burner pump is used in domestic and commercial heating boilers. The design is compatible with burners of most manufacturers.
