AdBlue pump

AdBlue pumps for trucks

An AdBlue pump is an important component of a truck's SCR system. The pump ensures that AdBlue is transported from the AdBlue tank under the correct pressure to the dosing system and the AdBlue injector. A properly functioning AdBlue pump is important for correct dosing and operation of the emissions system.

At BAS Parts & Tyres, you can find AdBlue pumps for various truck makes and models. View the range and search by vehicle details, part number or OEM number for a suitable AdBlue pump for your truck.

What does an AdBlue pump do on a truck?

The AdBlue pump transports AdBlue from the tank to the dosing system. In the process, the pump builds up the required pressure so that the correct amount of AdBlue can be injected into the exhaust system via the injector. The operation of the pump is controlled and monitored by the truck's electronic control system.

AdBlue pump as part of the SCR system

The AdBlue pump works together with components such as the AdBlue tank, lines, dosing module, AdBlue injector, NOx sensors and SCR catalytic converter. Together, these components help reduce nitrogen oxide (NOx) emissions.

How does an AdBlue pump work?

When the SCR system requires AdBlue, the AdBlue pump pumps the fluid from the tank to the dosing system. The system regulates the pressure and amount of AdBlue based on factors such as engine operating conditions and information from various sensors. The required amount of AdBlue is then injected into the exhaust gas flow.

How can you tell if an AdBlue pump is faulty?

A faulty AdBlue pump can cause insufficient pressure to build up or prevent AdBlue from being transported to the injector altogether. As a result, the SCR system may not function correctly and fault messages or warnings may appear on the dashboard.

Symptoms of a faulty AdBlue pump

Possible symptoms include an AdBlue or emissions warning, fault codes in the engine management system, insufficient pressure in the AdBlue system or problems with NOx reduction. Leakage or crystallisation around the pump and connections may also indicate a problem.

Common problems with AdBlue pumps

AdBlue pumps can be affected by wear, electrical faults, damaged connections, contamination or crystallisation. Problems with other components of the AdBlue system can also cause the pump to function incorrectly. A proper diagnosis is therefore important before replacing any component.

Crystallisation in the AdBlue system

When AdBlue dries, white crystals can form. These deposits may occur around connections and other system components and can affect operation. If crystallisation is present, it is advisable to also inspect the lines, connections and injector.

When should an AdBlue pump be replaced?

An AdBlue pump may need to be replaced if it no longer builds sufficient pressure, leaks or has an internal or electrical fault. Because similar symptoms can also be caused by other components of the SCR system, it is important to first check the fault codes and system pressure.

Which AdBlue pump fits my truck?

AdBlue pumps are generally vehicle-specific. The correct version depends on factors such as the make and model of the truck, the engine type, the emissions standard and the configuration of the SCR system. Connections and technical specifications may also vary between AdBlue pumps.

Search for an AdBlue pump by OEM or part number

The OEM or part number of the existing AdBlue pump is a useful aid when searching for a suitable replacement. Also check the vehicle details, connections and technical specifications to determine whether the pump is suitable for your truck.
