These notes will discuss the design and appraisal of pumping stations. Generally speaking a pumping station has the purpose of bringing a liquid to a higher lever or pressure or transport it from one point to another. This function is performed by the pump, essential element in a pumping station. The required power be supplied to the pump by driving device (motor/engine) very often through the medium of a transmission. This mechanical equipment is placed in a building, which provides foundation and shelter and system and is often an essential part of the system of inflow conditions, pipelines, etc.). It also houses the electrical and auxiliary equipment.ContentsIncroduction
