What to Consider When Buying a DEF?

Anyone who owns or operates a diesel engine must know how to store and transfer DEF. Here are considerations for purchasing the the best DEF pump in the market.

  • Construction materials: DEF is destructive to carbon steel, aluminum, copper, brass, zinc, and other minor metals. Stainless steel is the toughest for DEF pump construction.
  • Seals: Viton and Buna seals are the best elastomers for DEF use. Both are excellent rubberized solutions offering good compression and corrosion resistance.
  • DEF solutions: DEF distribution channels have proliferated since 2010. There are thousands of equipment options. Buying too much or too little may impact wear and tear, causing additional replacement costs. Consider consumption rates of DEF to diesel at about 2 to 3 percent for on-road heavy-duty vehicles.
  • Contamination: Everyone preaches contamination control when handling DEF. Transfer pumps are a significant step and must be looked at carefully. Always consider quality over quantity. Replacement costs for full, dedicated DEF systems can run into the thousands.

Best Ways To Pump Diesel Exhaust Fluid

There are several different ways you can go about pumping diesel exhaust fluid. However, some ways are better than others.

Below, we explore the top three most economical ways to pump diesel exhaust fluid:

  • Using A Hand Pump: You can purchase a pre-made DEF hand pump with customized length of hose, type of nozzle, fittings, etc. These are really handy, portable and easy to use.

  • Using A Gravity Kit: These kits take into consideration the fact that your tote may be above ground level – even higher than you! Many people store their totes on large cinderblocks or concrete platforms for examples. It’s all about flexibility with these devices.

  • Using A Tote Manifold Set Up: This is an excellent choice because it allows you to tie in two or more totes so that you can get the job done faster! Make sure you purchase this kit pre-assembled.

While all these devices will normally do the job in most cases, in the end, your choice will be based on your own personal circumstances. Always shop around to find the best option to suit your needs.
