The self-priming performance of fluoroplastic alloy chemical centrifugal pump can be said to be the main function that is different from other pumps, but sometimes the self-priming performance of fluoroplastic alloy chemical centrifugal pump is not very good, so why? 1. Determination of storage volume and storage height The liquid storage volume refers to the volume of liquid that can be stored...

The mixed flow centrifugal pump has the function of self-priming, and there is no need to install a bottom valve in the pipeline. It is only necessary to ensure that there is a quantitative drainage in the pump body before work to have the function of "one-time drainage, life-long self-priming". Therefore, the piping system is simplified and the working conditions are improved. In order to...
