Can vortex pumps (or swirl pumps, gas-liquid pumps) be used for liquid ammonia transport?
Thread Content
As the title suggests, have any of you used gas-liquid pumps, vortex pumps, or swirl pumps? Can it achieve the head? What kind of pump is generally suitable for transporting liquid ammonia?
For the transport and unloading of liquid ammonia, slide pump is recommended as a solution; previously some customers used centrifugal pumps, which suffered from severe cavitation, so they switched to slide pumps
We use nitrogen pressure for unloading liquid ammonia, and for transportation we use Sulzer centrifugal pumps, which works fine too. When transporting it, the pressure in the liquid ammonia tank needs to be maintained at 10 kilograms.
Shielded pumps, diaphragm pumps. Those with mechanical seals cannot be used!
