🔬 Safe Pumping of Liquid Ammonia: Why Magnetic Drive Gear Pumps Are the Right Solution

Anhydrous ammonia (NH₃) plays a key role in multiple industries: fertilizers, industrial refrigeration, NOₓ 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 20 °C)

Toxic, corrosive, flammable

Incompatible with many common metals and elastomers
