What type of pump is used to transport fermentation broth in bioengineering?
Thread Content
We have a bio-fermentation project, and the fermentation broth produced in the fermenters needs to be pumped to the filtration and separation unit； Since I’ve never done this before, could experts please advise me on what type of pump to use? It’s best to provide this as a reference for several manufacturers ； Thank you!
Please provide parameters such as the pump’s outlet pressure and flow rate. Plunger pumps can be used for fermentation broth. You can email me at kevinzhu@bj.melchers.com.cn
It would be best to provide the technical requirements; some require a clean environment, while others need insulation, and so on. It’s best to follow the requirements of the craftspersons
Considering several aspects: corrosion resistance, explosion protection, temperature, concentration, hygiene grade, etc
Provide information on the characteristics of the fermentation broth: temperature, viscosity, corrosivity, and whether it contains particles, etc. Based on past experience, a single-screw pump should be sufficient to meet the requirements; I can offer a reference solution
Screw pumps are good for your situation
Generally, it is classified based on hygiene standards and viscosity. If there are only a few particles and the viscosity is not high, a centrifugal pump with an open impeller can be used; if the viscosity is high, a screw pump or gear pump can be employed. I’m just sharing my knowledge here
There are many optional pumps, depending on your process and requirements.
A standard chemical process centrifugal pump will suffice; it has low maintenance costs and stable operation. If the corrosiveness is high and the viscosity is great, additional considerations are needed (this generally does not occur in products produced through biological fermentation).
