Submersible sewage pump with a head of 200 meters
Thread Content
I encountered a problem these past two days: the client’s application involves pumping wastewater from mining operations, and they need a submersible pump with a flow rate of 12.5 cubic meters (it can be higher), a head of 200 meters. The wastewater contains small stones about the size of rice grains; the exact solid content is unknown, but it’s not high. What kind of pump should be used in this situation? I’m looking for some information on this. Those who are able to help can message me privately; I’m waiting online. .

You can contact Shijiazhuang Slurry Pump Factory for information, or discuss the matter with manufacturers that specialize in transporting ready-mixed concrete. Is a head requirement of 200 meters a bit high? Has it been calculated?
Okay, thank you. The head is determined to be 200 meters
Slurry pumps should be the first choice, but an appropriate suction pressure must be selected.
The head of the submersible slurry pump cannot reach 200 meters
The wear of pumps caused by such media is a key issue. Could considering setting up a sedimentation tank for separation before extraction? It is indeed very difficult for a single-stage pump to achieve this head.
Assuming that the problem of medium wear is resolved, deep well pumps still need to be used due to the requirement for high head, and the design of deep well pumps results in a short service life. It’s really frustrating. . .
Most deep well pumps are multi-stage centrifugal pumps, and a screen can be installed at the suction inlet. There is a kind of well seepage sleeve available on the market; solutions should be possible from a filtration perspective.
Yes, I’ve considered that option. It’s just that ordinary manufacturers are unable to produce such a filtration system
It is recommended to go to the local teams that drill wells; they have what is needed.
