FUEL PUMP FOR AUXILIARY HEATER. A fuel pump for an auxiliary heater is a specialized component of a vehicle’s independent heating system designed to deliver fuel from the fuel tank to the burner of the heating unit. This pump ensures precise and metered fuel supply required for stable operation of the auxiliary heater and for maintaining the desired temperature inside the vehicle cabin or driver compartment. Auxiliary heaters are widely used in passenger cars, trucks, buses, special machinery and commercial vehicles to heat the interior without starting the engine. The fuel pump plays a key role in the operation of such systems because it supplies fuel to the heater combustion chamber in strictly controlled quantities. In most systems the pump operates in pulse mode and is controlled by the heater’s electronic control unit, which regulates the fuel supply frequency depending on the operating mode of the heater. The design of an auxiliary heater fuel pump typically includes a housing, an electromagnetic or electric drive, a valve mechanism and fuel connections for integration into the vehicle fuel supply system. These pumps are manufactured from materials resistant to fuel exposure, vibration and temperature fluctuations. Reliable operation of the fuel pump directly affects the stability of the heater, heating efficiency and fuel consumption. The catalog includes fuel pumps for auxiliary heaters designed for various heating systems and vehicle models.
