๐ฌ Safe Pumping of Liquid Ammonia: Why Magnetic Drive Gear Pumps Are the Right Solution
Anhydrous ammonia (NHโ) plays a key role in multiple industries: fertilizers, industrial refrigeration, NOโ reduction systems, and increasingly, as a hydrogen carrier and green fuel.
However, ammonia is also one of the most challenging fluids to handle:
Very low viscosity (~0.25 cSt)
High vapor pressure (8.6 bar at 20โฏยฐC)
Toxic, corrosive, flammable
Incompatible with many common metals and elastomers
