Water Resources: How A Submersible Pump Works

Brent Petring Pump Stations

Basic Impeller Theory The Impeller is the heart of the pump in a high flow pump station. It is the only part of the pump that adds energy to the liquid. Grossly simplifying the process, energy is added by accelerating the liquid from the smaller radius at the impeller inlet to larger radius at the impeller exit. The implications of this are that we can increase the amount of energy input into the fluid by increasing the outside diameter of the impeller or increasing the speed that it operates at. The Casing The Energy added by the spinning impeller exits as …
