description: This work is devoted to the design of a cantilever centrifugal pump and improving its performance by changing the spiral tap. 
The following tasks wee set in the work.
1. Study of design methods for the centrifugal pump stage;
2. Testing and refinement of the method for analysis viscous flow based on a cantilever pump, according to which there are experimental characteristics;
3. Design with the use of Ð¡ÐÐÐ  Ð¦Ð of volute case having a expansion coefficient of sectional area of the volute case: KS =0.90, 0.95, 1.00, 1.05, 1.10, 1.15, 1.20;
4. Investigation of the influence of the section area of the volume case on the flow pattern and characteristics of the pump using three-dimensional viscous flow analysis methods;
5. Performing cavitation analysis of the flow range.
The design of the cantilever centrifugal pump stage was carried out ac-cording to the methods developed at the Department of hydraulic engineering, in particular, method of S.A. Gorgidzhanyan. Further studies of three-dimensional viscous flow in the flow range were carried out in the ANSYS CFX software package.
The results of the analysis were the head and energy characteristics of the stages with volute case of various expansion coefficients of the volute case and the cavitation characteristic of the pump. The optimal option has been selected.
