Volvo Def Pump
Volvo DEF pumps are critical components in SCR (Selective Catalytic Reduction) aftertreatment systems used on modern diesel engines. These pumps move Diesel Exhaust Fluid from the DEF tank to the dosing module, allowing the system to reduce NOx emissions and maintain emissions compliance. At Advanced Truck Parts, we supply Volvo DEF pumps designed for dependable operation in heavy-duty truck applications.

Volvo DEF Pumps for SCR Aftertreatment Systems
SCR-equipped diesel engines rely on a DEF pump to maintain proper fluid pressure and supply Diesel Exhaust Fluid to the dosing injector. Accurate DEF delivery is essential for emissions performance, proper aftertreatment function, and preventing engine derate conditions.
Common Volvo Engine Applications
Volvo DEF pumps are commonly used across several heavy-duty diesel engine platforms found in highway and vocational trucks.
- Volvo D11 diesel engines
- Volvo D13 diesel engines
- Volvo D16 heavy-duty engines
- Volvo VNL and VNR truck platforms
Each DEF pump is designed to match the pressure requirements and electronic controls used in the Volvo SCR aftertreatment system.
Common DEF Pump Failure Symptoms
- SCR or emissions system warning lights
- Low DEF pressure fault codes
- Engine derate conditions
- DEF dosing system errors
- Crystallized DEF buildup or internal pump blockage
DEF pump failures may occur due to contamination, crystallized DEF deposits, electrical faults, or internal component wear. Replacing a faulty pump helps restore proper aftertreatment system operation and emissions control.
Verify Fitment Before You Buy
DEF pumps vary depending on engine model, emissions configuration, and truck production year. To confirm compatibility before ordering, provide:
- Engine Serial Number
- Truck year / model
- Current DEF pump part number
- Photos of the pump or connectors if available
This information helps ensure the correct Volvo DEF pump is selected for your truck.
