What is a DEF Pump? Everything You Need to Know

A DEF (Diesel Exhaust Fluid) pump is an essential component in diesel engines that helps reduce harmful emissions. It transfers DEF from the storage tank into the Selective Catalytic Reduction (SCR) system, where it reacts with exhaust gases to break down nitrogen oxides (NOx) into harmless nitrogen and water.

How Does a DEF Pump Work?

A DEF pump draws fluid from the DEF tank and injects it into the engine’s exhaust system. This process is crucial for maintaining emission compliance and ensuring optimal engine performance.

Key Benefits of a DEF Pump:

✅ Helps diesel engines meet emission standards

✅ Ensures efficient DEF delivery and flow control

✅ Prevents crystallization and contamination

✅ Extends the life of the SCR system

Types of DEF Pumps

• Electric DEF Pumps: Automated pumps for precise control

• Manual DEF Pumps: Ideal for small-scale use

• Bulk Transfer DEF Pumps: Used at fueling stations and industrial applications
