Are there pumps with very low flow rates?
Thread Content
Our laboratory is planning to buy a pump with a low flow rate – the flow rate should not exceed 1 cubic meter per hour. The head pressure should be around 5 meters, or even less; it would be better if the pump were sealed, as the medium is volatile. I’m not sure if such a pump exists

There is nothing that can’t be done if you only put your mind to it; by contacting a few more pump manufacturers, you will be able to find what you need. As an example, the pumps used in computer water cooling systems seem to meet the requirements pretty well. (Not recommended) Be good at imagining possible solutions. Pump manufacturers do not produce ones this small. The possibility of concealing the request can be considered from other perspectives!
I ordered a centrifugal pump with a flow rate of 1 cubic meter, but its head was 20 meters... I contacted manufacturers of centrifugal pumps, who said they couldn’t produce one; I could also consider diaphragm pumps or metering pumps
A \"fish tank pump\" could be considered, dropped into the solution. Make sure to seal the wires and water outlet pipes (seal them with glue). It's just an experiment after all, so long-term considerations aren't taken into account. Some time ago I built a small device for desulfurization testing, and it gave me quite a few headaches; I bought one from a flower and bird market for 50 yuan, and its performance was good.
Thank you all. Just now, one of our colleagues suggested using a machine tool cooling pump, but we’ve never seen what it looks like and are not sure about its sealing performance
I’ve heard of a computer water-cooling system pump for the first time on the second floor; it’s quite new :)
