Pumping Ammonia

Ammonia is widely used as a refrigerant gas and has a low specific gravity and viscosity which can present particular problems for un-specialised pumps.

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 also used as a refrigerant gas, for purification of water supplies, and in the manufacture of plastics, explosives, textiles, pesticides, dyes and other chemicals. It is found in many UK households and industrial-strength cleaning solutions.

Challenges when pumping Ammonia:

There are many challenges when pumping ammonia such as low NPSHa, fluid slippage, poor lubrication in the pump chamber and boiling. In addition to which any slight problem with the pump's mechanical seal will result in off gassing.

The main considerations for handling liquid ammonia in a pumping system are to contain the fluid and vapour lock. Ammonia gas tends to be very harmful to the lungs Cast. Where ammonia is a gas handled under pressure, a leak in the system or the pump unit itself can potentially release ammonia into the atmosphere, therefore posing risk to the individuals located nearby. Thus making it crucial to select the correct pump to not only optimise efficienct and cost effectiveness, but also individual welfare.
