Stability of centrifugal pump characteristic curve
 Chmatil, Ľuboš ; Haluza, Miloslav (referee) ; Pochylý, František (advisor)
This thesis includes the theoretical part explaining problematic of centrifugal pumps, Y(Q) characteristics of these centrifugal pumps and stability of these characteristics, ways and conditions for stabilisation and adaptations heading to stabilisation.

Positive displacement pump design
 Klapka, Petr ; Šperka, Oldřich (referee) ; Klas, Roman (advisor)
This thesis gives an overview of the structure of hydrostatic pumps. First, there is shown the integration of the hydrostatic pumps between other hydraulic machines and then there are described the fundamental relationships and characteristics. The main objective of this work is to make a basic list of species distribution and the classical hydrostatic pumps. For each type, while mentioning his principle, his description of the main members is also highlighted some of their advantages and disadvantages.

Theoretical and experimental setting of the side channel pump specific energy
 Dančák, Zdeněk ; Habán, Vladimír (referee) ; Fialová, Simona (advisor)
This master’s thesis deals with side channel pumps. Derivated formula of specific energy is supplemented by other equations and the results of CFD simulation. Further are analysed the mechanism of energy transfer from the impeller and external characteristics of the pump.

The design of hydraulic diffuser for the pump for two operational points.
 Dobšáková, Lenka ; Žák, Radim (referee) ; Žák, Radim (referee) ; Haluza, Miloslav (advisor)
The pump is suggested for optimum operation point wherein usually works. If the machine works in the areas of flows except for design point, it will cause decrease in its efficiency or genesis of pulsation. The compromise solution is possible to use the pump in a large range of flows together with high efficiency. The solution is diffuser with double curvature of vanes.
