5483862 Fuel Transfer Pump For Cummins QST30 Engine

The fuel pump is one of the basic components of the fuel injection system in electronic fuel injection vehicles, located inside the vehicle's fuel tank. Its function is to extract fuel from the fuel tank, pressurize it, and deliver it to the fuel supply pipe, working together with the fuel pressure regulator to establish a certain fuel pressure.

The pump body adopts a multi material composite structure to balance corrosion resistance and mechanical strength: the main structure is made of cast steel material, which has the characteristics of high pressure resistance and vibration resistance, and can adapt to the harsh environment inside the engine compartment; The core component impeller shaft is made of 45 grade powder metallurgy material, and the stator is made of magnetic steel to ensure efficient and durable power transmission; The sealing material is made of oil resistant NBR rubber, and the filter and outlet are made of nylon plastic, which not only ensures fuel sealing but also filters impurities.
