Diesel Exhaust Fluid pumps and crystallization
Diesel Exhaust Fluid is considered in the industry as a
“creep” product. This simply means that Diesel Exhaust
Fluid will nd its way through every possible opening.
Once Diesel Exhaust Fluid is exposed to air, the water
will evaporate leaving behind a “crystallized” white
powdery residue. This residue can be cleaned with
de-ionized water and a bit of scrubbing. As you can
imagine, allowing the Diesel Exhaust Fluid to “crystallize
in a pump is not a good idea. It can lead to premature
pump failure.
Here are some best practices to follow:
- Don’t allow the barrel, tote, or tank to run dry.
This introduces air into the pump and will cause
“crystallization”
- If at all possible, the pump should be used regularly to
keep “crystallization” to a minimum.
- If the Diesel Exhaust Fluid pump will not be used for
an extended period of time, it should be ushed with
de-ionized water to prevent ‘crystallization”
- If “crystallization” has occurred in your pump, don’t
try and pump it out. Open the pump and clean it with
de-ionized water
- Following these practices will ensure that your True
Blue pump will last and deliver Diesel Exhaust Fluid
as expected.
