- High load capacity: Resistant to vibrations and temperature fluctuations.
- Durable materials: High-quality, corrosion-resistant components ensure a long lifespan
- Cost efficiency: Reduced maintenance effort and longer lifespan result in lower operating costs.
- Quick and easy installation: HELLA AdBlue pumps are specifically developed for the needs of the commercial vehicle market and enable fast and straightforward integration into existing systems.
How do HELLA AdBlue pumps work?
AdBlue is a high-purity, synthetic urea solution used in vehicles with SCR technology for exhaust aftertreatment. HELLA AdBlue pumps ensure precise dosing of the AdBlue solution.
AdBlue pumps are dosing pumps that transport the AdBlue solution from the tank to the injection pipe in the exhaust system. The pump unit typically includes an electric motor that drives the pump mechanism, which consists of a diaphragm, a filter, a heating element, a housing, and a pressure sensor that ensures a constant supply of the correct amount of AdBlue.
Details:
- Precise dosage: HELLA AdBlue pumps ensure even pressure and optimal dosing of the AdBlue solution.
- Durable construction: The electric motor, diaphragm, pressure sensor, filter, heating element, and robust housing provide maximum reliability.
- Protection against damage: Corrosion-resistant materials prevent damage caused by impurities and extend the lifespan.
When should the AdBlue pump be replaced?
The AdBlue pump should be regularly maintained and replaced if necessary to ensure the proper function of the exhaust treatment system. Several factors can lead to premature wear or damage to the pump.
- Contaminations:
One of the main causes of damage is the use of AdBlue that is contaminated with fuel, dirt, or other impurities. Such contaminants can block the pump and significantly impair its function.
- Crystallization:
In addition, crystallization of the AdBlue solution within the pump can occur if the purge cycle is not fully completed, such as when the vehicle is switched off. This causes the pump to seize and no longer operate correctly.
- Wear and tear:
Electrical issues or normal wear from regular use can also lead to pump failure. If the pump can no longer build the required pressure to ensure precise dosing of the AdBlue solution, it will generally need to be replaced to maintain effective exhaust aftertreatment.
