What type of pump should be chosen in this case?
Thread Content
There is an underground tank; it is necessary to first remove the lighter liquid from the upper layer, and then remove the thicker material from the lower layer. What type of pump should be used? It must be possible to apply the upper layer of material first and then the lower layer, so that the operation is convenient. Please advise me, experts! Thank you first!
Just choose a pump based on the properties of the thicker material
I’ve heard of this for the first time; I wonder if there are lift-type submersible pumps? Can two chambers be used inside this underground tank to separate the two materials in advance, with pumps used to handle each one separately?
Reply to 3# liuisiman: The material in the tank needs to be left to settle and separate into layers; the material at the bottom is thicker and tends to settle. To remove this bottom material, stirring is required, so it’s necessary to first remove the liquid from the upper layer. I started using submersible pumps, and I wanted to move the pump up and down; however, I found this method to be rather inconvenient to use. So I’m wondering if there are any better alternatives
Can’t we use two different pumps? Do we really have to use just one pump?
Reply to 5# zhaoyu532: Yes, use one pump
Actually, you only need to use one method: install a sight glass outside the pump outlet, and use the information provided by this sight glass to determine when to inject which material. If you feel this isn’t sufficient, you can add an intermediate tank at the pump outlet, which will prevent the materials from mixing together. I don’t know what kind of materials you are using, but if you pour all of these materials into a high-level tank, these problems can be solved through stratification. As for the pump, it can be selected based on the properties of the materials in question
