How to Handel the Diesel Exhaust Fluid (DEF) Solution

Diesel Exhaust Fluid (DEF)

Diesel Exhaust Fluid (DEF) is a reactant which plays a big role in SCR process. It is a nontoxic and aqueous solution of 67.5% water and 32.5% urea. The urea is a chemical compound of nitrogen that turns to ammonia at the time of heating. DEF is extensively used in a number of industries commonly in agriculture and fertilizer.

The fluid is neither dangerous nor inflammable while handling. But it is extremely corrosive to metal, especially aluminum and copper.

Diesel Exhaust Fluid (DEF) Handling

While handling the DEF solution, it is essential that process connectors be properly connected or accurately encapsulated. Otherwise there can be a risk that DEF may cause oxidation that cannot be noticeable. Compressed air or water does not work as DEF oxidizes metal very quickly.

In case a connector comes in contact with the DEF solution, it is necessary to be rinsed without wasting any time to avoid DEF solution from creeping into the copper wiring.

What You Should Know about Spilled Diesel Exhaust Fluid (DEF) 

If the DEF solution is completely spilled onto any vehicle, make sure to wipe off the rinse and excess with water. The spilled DEF solution can create white crystals on your vehicle. So, it is better to rinse off such crystals with water. 

If the urea solution comes in contact with your skin, rinse with water and try to remove the contaminated clothing.

A nozzle is commonly a tube or pipe of the varying cross sectional areas. It can also be used for directing or modifying the flow of a fluid (gas or liquid). The nozzle is commonly used in checking and controlling the rate of flow, mass, speed, direction, shape and the stream pressure.

Benefits of Fuel Nozzle:

  • Higher initial cost
  • Maximum reach with available water
  • Nozzle flow control
  • Reliable hard-hitting streams
  • Nozzle reaction is a direct indication of flow
  • Adjustable to the varying conditions of water supply
  • Accurate nozzle pressure with suitable flow

Types of Fuel Nozzle:

Jet: A hydro jet, fluid jet or gas jet is a nozzle used to eject the fluid or gas in a coherent stream. A gas jet is usually found in barbecues, ovens or gas stoves.

Installation of DEF Pumps into Totes and Drums


Before installing DEF (Diesel Exhaust Fluid) pumps into totes and drums, it is important to know everything about DEF. This would give you a good idea on how to take the appropriate steps and find out the best solution for you. DEF is an organic and non-toxic compound composed of 67.5% DI water and 32.5% urea. In a Selective Catalytic Converter System (SCR), the diesel exhaust fluid is included to the diesel exhaust. It happens in presence of a catalyst to change the smog producing nitrogen oxide into safe water vapor and nitrogen.

After that, the emissions in the exhaust can meet the new stricter emission standards of EPA for new diesel vehicles. In order to meet the new guidelines, diesel trucks have the on-board DEF storage tanks that range from 16 to 30 gallons.The main requirement of a SCR system is the steady refilling of such storage tanks.

How are DEF Pumps used?

In order to fill storage tanks, you can use drum transfer pumps for a higher volume and an open system container,seal-lesscentrifugal pump for an effective custom engineered dispensing system. It is important to employ only reliable DEF pumps for high-quality and non-contaminating materials that do not have to compromise the strict purity requirements of diesel exhaust fluid.

Installation of DEF Pumps into Totes and Drums 



You can use a barrel adapter to install a DEF Pump into a 55 gal (208 L) or 330 gal (1249 L). Ensure that the barrel adapter is added properly with the each pump in a right order. In case you face any trouble in the process, get in touch with the customer service provider of the manufacturer. If the DEF pump is in the warranty period, it would be installed or repaired as per the requirements.

Warning: Always protect the drum to prevent tipping. DEF is pumped through the drum, and particularly when there are only a few gallons left, so make sure that the unit should be top-heavy. This would prevent any unexpected situation and help you use the DEF pump without any trouble.

Caution: Ensure that you transfer the DEF pump directly from the used container to a new one. Never allow the pump to get in touch with any foreign material. 

Ordering of the DEF pump is the most crucial aspect that you should consider for the best outcome. This will give the optimum result and help you work on it efficiently.

Standards of Cam & Groove Couplings



Cam and groove couplings are also known as cam lock fittings, and are used for hose connections to prevent leakages. These couplings are popular because of their easy usage and affordability to reconnect and disconnect. These can be used in systems in which rapid filing of chemical drums happen.

Cam and groove couplings also have some standards for diverse purposes.Here are some of those standards:

Federal Mil A-A-59326A 

This standard for cam and groove couplings is based on the US Military Specification Mil-C-27487.It specifies the inspection procedures, casting methods,pressure ratings, dimensions, materials and tolerances.In 1998, the specification of Mil-C-27487 was changed by Federal Military standard: A-A-59326A.This new standard guarantees the interchangeability of couplings which are designed to the similar specification. 

EN 14420-7 

This European standard was permitted by CEN in 2004. It was also used to cam and groove couplings designed to American“military specification” MIL-C-27487 / A-A-59326A.The US standard does not employ the connection side, instead the coupling side. Some other parts such as seals, levers, rings and boltsare not standardized.

DIN 2828 

Original MIL-C-27487 can be interchangeable to DIN 2828 standard. However, DIN 2828 varies in terms of hose tail part number, design etc.
