The correct choice of electrically driven centrifugal pumps and the planning of pumping stations, whether small for domestic water supply or larger for industrial plants and local communities, requires knowledge of the necessary basics. These are primarily: a) the precisely defined purpose of the pumping station, b) the water demand and its fluctuations over time, c) the possibility of obtaining water, the yield of the water pumping, as well as the quality and properties of the water, d) the local conditions regarding location, differences in height, and the pipe network, and e) the required pressures at the discharge points. In addition, for the designer to find the most favorable solution in each case, knowledge is required of f) the basic operation of centrifugal pumps and their operating characteristics, g) the various types of pumping systems and their operating characteristics, h) the various types of pumping systems, and i) the various types of pumping systems.
