Regarding pump selection
Thread Content
Dear experts: I would like to ask for your advice. I have a 28-meter-long low-temperature storage tank that holds a medium at temperatures ranging from -33°C to 50°C. Without considering pumps installed inside the tank, what type of low-temperature pump should be installed outside the tank to meet the requirements? What factors should be considered when selecting a pump like this?
For large-scale low-temperature storage tanks like these, internal pumps are often used, but they are too expensive, and only a few companies manufacture them; these companies can be considered monopolists in the field of low-temperature pumps. We are considering whether it would be possible to achieve the input and output of the fluid by eliminating internal pumps and installing only external pumps
