Pumps that can transport both gases and liquids
Thread Content
I’m currently working on a test setup for vapor-liquid equilibrium, and I need a pump that can handle both gases and liquids for circulation. The fluid temperature is around 200 degrees, the pressure is below 15 bar, and the flow rate is 200 ml/min. Does anyone have experience with such pumps? Please recommend some options. Thank you! Some literature mentions that Nanjing Tech University has such pumps; does anyone know anything about this?
What proportion does the gas content account for? It is said that it could be below 7–10%, but I find it hard to believe it; those who work in process engineering know that pumps hate \"gas\" the most.
What I need is a small pump for laboratory use, one that transports not a two-phase gas-liquid mixture; it should transport gas at one time and liquid at another, with the switching being done via valves
This situation mentioned by the poster is something I’ve encountered for the first time; theoretically, it’s entirely feasible, but I’m not sure if there are any products like that available. For example, when using a reciprocating pump, two speed ranges can be set. Using a low speed when transporting liquids and a high speed when transporting gases can solve this problem.
It is said that there are pumps capable of transporting all three phases—gas, liquid, and solid—at the same time, with 30% vol of gas and 10% mt of solids. But I don’t know which company manufactures it? If any friends who are near the sea know about this, please let me know at dxcyzg@163.com. Thank you!

Pumps are generally used to transport liquid media, while fans or compressors are used to transport gaseous media
Different processes require different equipment solutions, and there is no uniform approach
