Progressive cavity pumps have a wide range of application in industry because of its simple construction and ability to transport media with different kind of viscosity. Also, because of their modular construction, the maintenance of these kind of pumps is simplified. The only limiting factor of application for this kind of pumps is represented by the temperature of transported media. In this bachelor thesis there is described the basic division of pumps, there is specified the application areas of pumps in industry and there are also given some of their characteristic and also some of frequently processes that are likely in operation of these pumps. Furthermore, it is explained the basic work principle of progressive cavity pumps and there is also given division of screw pumps. More detailed is described the construction of one-screw progressive cavity pump, where a special attention is given to cardan shaft and rotor of progressive cavity pump. In the practical part of this bachelor thesis is shown the technological process of production a rotor for the progressive cavity pump made on classical tool machines. In that part there are listed all necessary processing procedures and belonging tools and tools machines.
