User Tested DEF (Diesel Exhaust Fluid) Systems
          User tested PUISI DEF dispensing systems and components are always available from Industry Depot
          Stricter EPA diesel exhaust emission standards were mandated in January 2010. These regulations require reliable, safe and non-contaminating fluid dispensing systems manufactured with materials suitable for handling DEF (Diesel Exhaust Fluid) fluid.
          DEF is an organic, non toxic compound composed of 32.5% urea and 67.5% DI water. In a Selective Catalytic Converter System (SCR), diesel exhaust fluid is added to the diesel exhaust in the presence of a catalyst to convert smog producing nitrogen oxide into harmless nitrogen and water vapor. The treated exhaust must meet the strict EPA emission standards for new diesel vehicles as mandated on January 1, 2010. To comply with these regulations, diesel trucks have on-board DEF 16 to 30 gallon capacity storage tanks.
          Since 1953, PUISI SpA has been a leader of the lubricant and fuel transfer market, specializing in pumps, meters, compressors and measurement devices.  Their innovative solutions have involved PIUSI in commercial, industrial and government facilities reducing NOx emissions since 2004. 
          PIUSI SpA established PIUSI USA to bring their high quality DEF dispensers, pumps and meters to the North American transportation industry.  These dispensing systems are essential to reliable, economic, non-contaminating handling and transferring of DEF (Diesel Exhaust Fluid) to on-board truck storage tanks in compliance with ISO 22241-3. 
DEF Dispensing Systems
Suzzsts Pro DEF Tote System
DEF is normally dispensed from  275 gallon and 330 gallon totes and 55 gallon drums.
The tote systems consist of a pump, hose and a nozzle that can be supplied with or without a flow meter and connections to a tote that is usually supplied by the DEF fluid supplier.  DEF drum dispensing systems are similarly equipped but with either a stainless steel base for fixed location installations or with a wheeled trol for moveable convenience.
All equipment is designed with attention to preventing DEF contamination.  Key components including pumps, meters, hoses, nozzeles and fittings have been specially developed to avoid contamination and also to facilitate monitoring and reporting usage.

          An optional pulser display is available to connect to an external receiver.
HOSE REELSDEF transfer hose reel
          Hose reels are specifically made for DEF use. Designed to limit pressure loss and facilitate use even for high flow rate DEF refueling systems.
