Centrifugal pump impeller model
Thread Content
Are there standards for centrifugal pump impeller models? How should I choose?
Standards are in place. The parameter report is sent to the pump manufacturer, and they will choose one for you.
Indicate the pump model; purchased from the original manufacturer, so it can’t be wrong
There is no specified standard for impellers. Most manufacturers modify the impellers according to different operating conditions; therefore, even for pumps of the same model, the size of the impellers can vary.
No, the sizes of the impeller blades vary among different manufacturers. Either buy them from the original manufacturer or find a company that specializes in producing accessories online
Such a rigid question: lol, you need to hire someone who has worked in a pump factory; P
The model of this impeller is the same as that of the pump; when placing an order, you only need to specify the pump’s model and the material of the impeller； Your question is a bit tricky ； The impeller can be cut; firstly, open, closed, and semi-open impellers can all be modified through cutting. For example, a closed impeller can be transformed into a semi-open one ； Then, for some pump models, A or B is indicated thereafter; A refers to pumps that have been cut once (which results in changes in both head and flow rate), while B refers to pumps that have been cut twice. . . . You can look up information on this
Provide the manufacturer with the complete model number of the pump, and they will help you select the appropriate model

For each pump model produced by the manufacturer, the performance curve typically includes impellers in 4 different sizes. In the performance curve showing your flow rate and head, the differential method can be used to initially determine the impeller size, provided you have the data provided by the manufacturer.
