I am using conventional method to design a water pump impeller. But my blade profile is too long. I want to shorten the length of the blade by keeping the inlet and exit angles same. What are parameters I can play with to reduce the length.

Looking at my vane profile, smoothening the blade profile and IGV profile and underfiling are the things I should do first and see if there is any improvement. Thanks a lot for your valuable suggestions.
1. It is a centrifugal water pump
2. The pump is expected to operate at two operating points. i. 3000rpm with a flow rate of 5lit/m, head 5m(ii). 5500 rpm with a flow rate of 20lit/min expecting 7.6m of head.
3. Please find the attached pump curve.
4. The impeller is of 53mm in diameter.
Please...
This pump has already been designed by someone else for a customer. The input power(elec) is 50W for this pump whereas output power is only 10W. The flow phenomenon is not very good over the impeller and the volute exit. They do not want to change any of the external dimensions of the pump...
Hi,
I am working on improving efficiency of centrifugal water pump. My pump was designed at 20 lt/min running at 5500 rpm with 6 impeller blades(closed impeller). Do you think there is any benefit of changing from closed impeller to open impeller. I am looking in to different factors like 1...
