Is the gas-liquid mixture transported using a pneumatic pump?
Thread Content
At present, our factory has a wastewater tank, and the wastewater in it needs to be circulated using pumps. The wastewater contains foam-like air bubbles; due to its high density, cavitation occurs when using centrifugal pumps or submersible pumps. Have you encountered similar situations? Please advise on which pump to choose. Could you help analyze whether a diaphragm pump is feasible?
Diaphragm pumps or gear pumps can be used; it is not affected by the medium.
Use a twin-screw pump; gear pumps cannot evacuate a volume.
It shouldn’t work to run a twin-screw pump under vacuum for a long time either; the lack of a lubricating medium leads to wear. Has anyone ever used it successfully?
Hasn’t the twin-screw pump been successfully applied to the transportation of oil and gas mixtures?
Personally, I think it’s better to use a pump – it’s more durable
