What are the advantages of low-flow, high-head vortex pumps?
Thread Content
For example, under suction conditions, the self-priming height is only three meters. Flow rate: 2 m3/h, head: 80 meters. Medium water, virtually free of impurities. In this case, both self-priming centrifugal pumps and vortex pumps can meet the requirements; which one performs better?
If anyone has used it or is familiar with it, please share your thoughts
Hang on, the operating conditions seem good. What’s the efficiency like? I’m not familiar with vortex pumps; self-priming centrifugal pumps seem to have relatively low efficiency, so we should choose the one with higher efficiency

Huh? This is really the first time I’ve heard of it. Thought they all had a self-priming function
Well, aren’t such self-priming pumps all multi-stage pumps?
There is also a type called a side-channel pump; you might want to take a look at it. Both Xihe and DICKOW offer such pumps

A self-priming pump is capable of transporting both gas and liquid, but its inlet and outlet channels are not connected to each other; it can therefore be used as a self-priming pump； However, the inlet and outlet channels in the pump are connected to each other, so self-priming is not possible; a self-priming mechanism must be added to the inlet
