Explosion Proof

Explosion Proof Pumps 

Electric motor driven chemical pumps for Hazardous duty made by AMT. These centrifugal pumps are available in Cast Iron or Stainless Steel construction. The EXP pumps come in both End Suction (flooded inlet) or Self Priming designs. Sizes range from 1/2HP to 15HP. Motors are UL listed EXP (C 1, Gp C/D & C11, Gp F/G). Others available upon request.

Would include those pumping chemicals, solvents or other fluids with a low flash point as defined by UL and NEC or simply in a Hazardous location which requires EXP machinery. Check with your local authorities if not sure. 

Hazardous Duty pumps 

Typically the type of water and the classification of the space are the main factors in deciding when to use explosion proof pumps. In the majority of wastewater applications, explosion proof pumps are preferred so that gases coming off the water cannot trigger an explosion. Industrial water applications can also require explosion proof pumps, such as with oily water, chemical water, cleaning water, and more. With clean water and most stormwater scenarios, explosion proof pumps are typically not required or necessary. The designations for a hazardous area may also require explosion proof equipment be included in a pump station. Typically, these areas will be Class I, Division I, but other designations – like zones– can have the same impact. Aside from these common situations, there are additional factors that may require the inclusion of explosion proof pumps. Pumps and containers need to be bonded and grounded according to the relavant safety codes. Exp. Proof Classes: Class 1, Group D, Class 2, Goups E,F,G or FG.
