Diesel Exhaust Fluid (DEF) was developed to help keep heavy-duty diesel fueled machinery like boilers operating within federal emissions standards. At the chemical level, DEF is a combination of 67.5% de-ionized water and 32.5% urea that transforms harmful nitrous oxide emissions into harmless water and gas.

Urea is an organic chemical compound produced as waste by the body after metabolizing protein—but the urea used in DEF is not (despite some confusion on the subject) derived from human or animal urine. For nearly two centuries, scientists have been able to create synthetic urea, which is much more appropriate for the DEF application.

DEF isn’t actually a fuel additive, and it never comes in contact with diesel. Rather, it is stored in a separate tank and is pumped into the exhaust stream of diesel machinery to break down dangerous NOx emissions into safe nitrogen and water. This process is called Selective Catalytic Reduction (SCR).

Changes in EPA emission standards have required diesel burning machines to reduce their output, and SCR is the technology of choice for this purpose. As emission standards have continued to expand to include off-road vehicles, generators, and a variety of engines, the use of DEF is becoming more and more widespread.

To properly deliver DEF, the Diesel Exhaust Fluid Urea Pump system is designed to safely and effectively transfer DEF fluid from a tank to diesel equipment, helping facilities comply with strict NOx emission regulations. Constructed using stainless steel piping and pumps, the DEF system lasts in even the most abusive outdoor environments. We proudly make DEF Urea Pump Systems in the USA. Here are the specifications:
