Turbine pumps typically have a high head
and high discharge pressure for their size and speed. It is not uncommon for turbine
pumps to produce heads over 1000 feet, at relatively low RPM compared with other
This high head from a single rotating impeller is caused by the unique operation of the pump.
As fluid goes from intake to discharge (in just under one revolution) it circulates around and around as shown in the lower (side view) drawing. Each time it passes the turbine blades (shown in gray) it gains additional pressure.
For relatively low flow rates this pump is often more efficient than a comparably-sized centrifugal pump.
This pump is commonly used for clean fluids of low viscosity because of the close tolerances needed between the blades of the turbine and the casing,
