Progressing cavity pumps for explosion emulsions

This falls into one of the more interesting applications we see - pumping of ammonium nitrate.  We commonly see these applications in the mining market.  Progressing cavity pumps are the pump of choice here because of the low shear that they apply on the product as well as the high viscosity of the explosive liquid.

Why is the right design important or what are some of the hazards users might experience when pumping ammonium nitrate?

• Deadhead pumping which is caused by cooled down emulsion explosive forming a plug or by a foreign object
• Dry pumping which generates excessive heat and may result in ignition of explosive residue

These are just some of the reasons the Allweiler branded pumps are the pump of choice.  Allweiler pumps applied in this application are intrinsically safe and have met (or can meet) the necessary hazard operation reviews required.
