Liquid ammonia pump usage
Thread Content
Our company currently uses this type of positive displacement vane pump for liquid ammonia, and the frequency of inspection and maintenance is a bit high. I want to change the pump, but I don’t know what type of pump your company uses?
Although the positive displacement pump has high efficiency, the lubricity of liquid ammonia is very poor and the blades are seriously worn. It is recommended to at least change to a centrifugal pump, and a magnetic pump/canned pump is better.
It is not recommended to use the belt type because it will generate static electricity
