In recent years, the demands on pumps and pumping systems, especially those for pumping contaminated wastewater, have increased significantly. This is primarily due to urbanization and water scarcity around the world. The conditions for the discharge of wastewater have changed, the content of solid particles in wastewater has increased, and the duration of the stay of water in the sewer network has increased. In this regard, the life cycle costs of a pump are of paramount importance to the user, ranging from price and maintenance costs to damage due to downtime and repair costs.
