In the world of diesel engines DEF defines the latest in reducing harmful exhaust emissions. DEF is an acronym for Diesel Exhaust Fluid, an important component that minimizes nitrogen oxides (NOx) in a technology called Selective Catalytic Reduction (SCR). DEF itself is a carefully blended aqueous urea solution of 32.5 percent high purity urea and 67.5 deionized water.
Small quantities of DEF, are injected into the diesel exhaust upstream of a catalytic converter where it vaporizes and decomposes to form ammonia and carbon dioxide. The catalyst them converts the nitrogen oxide into harmless nitrogen (N2) and water (H2O).
For industries that maintain fleets of diesel powered trucks and equipment with these systems, Finish Thompson (FTI) has just the pump to transfer DEF supplied to them in drums or totes to the truck holding tank. Finish Thompson DEF drum pumps are designed for years of reliable service while maintaining the strict purity requirements of DEF. The system, sold as a kit, includes a polypropylene pump tube to match the container size, your choice of motor (air or electric), a sealed bung adapter, eight feet of DEF dispensing hose and a stainless steel automatic shutoff nozzle. FTI also sells these components separately.
Separate kits are available with tube sizes for a five gallon bucket up to a 330 gallon tote. A choice of two pumps are available: an economical 5 GPM (EFP Series) or a high performance 10 GPM (PFM Series) version. The dispensing hose is made of EPDM elastomer and is peroxide cured and flushed with deionized water. The 19 mm shutoff nozzle is specifically designed for the on-board storage tank on the engine.
To sum it up a Finish Thompson drum pump is the most ‘def’ for DEF!
