At AxFlow we have a range of different pumps available across the UK, specially selected and suitable for pumping ammonia. These products are centred around magnetic dive and canned pump technologies as we believe these are the best for ammonia pumping applications.
Ammonia is widely used across industrial processes, particularly as a refrigerant, and it is also found in water treatment, chemicals, textiles, pesticides, dyes and cleaning solutions. Its low specific gravity and low viscosity can create challenges for pumps that are not designed for this duty, making correct pump selection essential for safe, reliable operation.

Why Ammonia Is Difficult to Pump
Liquid ammonia presents a number of handling challenges. Low NPSHa, fluid slippage, poor lubrication in the pump chamber and boiling can all affect pump performance. Where mechanical seals are involved, even a slight issue can result in off-gassing, increasing both operational and safety concerns.
Containment Is Critical in Ammonia Pumping
When pumping ammonia, containment is one of the most important considerations. As a pressurised fluid and refrigerant, any leak from the pump or system can release ammonia into the atmosphere. Selecting the right pump technology helps reduce leak risk, protect personnel and support efficient long-term operation.
Pump Technologies for Ammonia Applications
Magnetic drive and canned pump technologies are well suited to ammonia pumping duties. These seal-less designs help reduce the risk of leakage while supporting reliable transfer of low-viscosity fluids in demanding operating conditions. For ammonia applications, these technologies offer a practical solution where safety, containment and consistent performance are priorities.
Reliable Pumping for Refrigeration and Chemical Processes
Ammonia pumps are used in applications where stable transfer, safe containment and dependable operation are essential. In refrigeration systems and other industrial processes, pump performance must be maintained despite the fluid’s low viscosity and tendency to vaporise under challenging conditions. The right pump solution helps support process continuity while reducing maintenance and leak-related risk.
