Selection of high-density medium pumps
Thread Content
Suspension containing 60% particulate impurities; particle size: 3 microns; specific gravity: 6. Flow rate: 2–3 cubic meters; head: 10–15 meters. Operating at normal temperature. Please help with model selection – the diaphragm pump currently in use requires its diaphragm to be replaced every 10–15 days.
A centrifugal pump with an open impeller is sufficient, as it requires neither high flow rate nor high head pressure.
For screw pumps, it is preferable to choose those with a low rotational speed! After being in contact with the peristaltic pump for a while, it dispenses a substance similar to toothpaste; I think there should be no problem using it for you!
I think the medium you’re referring to is coal water slurry, right? Screw pumps are good – they operate stably. Remember to replace the stator regularly, and their operating costs aren’t low either!
The screw pump probably won’t work; it’s better to use an open-type centrifugal pump.
