Anotace:

Students will get knowledge on the basic types of hydrostatic and hydrodynamic pumps, their construction and their operational properties. They will also learn about the safe, economical and reliable operation of hydrostatic and hydrodynamic pumps in machine systems and will gain a more comprehensive orientation in choice of type, design and operation of pumps included in the systems for pumping liquids.
