Pump efficiency is mainly related to the application scenario, as each type of pump has its own advantages. For example, peristaltic pumps are most advantageous in clean and hygienic transport, but are they highly efficient? It’s hard to say. For instance, in terms of flow rate, peristaltic pumps have a relatively small flow rate, so their efficiency is not high compared to other pump types. It’s much easier to analyze efficiency by relating it to the application scenario, mainly focusing on the following three:
1. Flow-rate transport: When the application only focuses on flow rate, centrifugal pumps and other impeller pumps are very efficient due to their large flow rate.
2. Suction or head transport: In this case, since suction and head require relatively high pressure or thrust, positive displacement pumps are more efficient.
3. Clean and corrosion-resistant transport: When the application requires hygienic and food-grade materials, and the pump chamber needs to withstand corrosion, peristaltic pumps are very efficient.
