There are significant differences between self-priming centrifugal pumps and ordinary centrifugal pumps in terms of self-priming capacity, applicable scenarios, body structure, starting method, performance characteristics, efficiency and cavitation performance, as well as device and installation. Which pump to choose depends on the specific application and needs

The self-priming centrifugal pump generates negative pressure through the rotation of the impeller, sucks in liquid and air, and then uses centrifugal force to separate the liquid from the air in the mixture, ultimately achieving continuous liquid delivery. This pump has the advantages of strong self-priming ability, simple structure, and stable operation, and is widely used in industrial and civil fields.
