Turbine and Jet Pumps

A turbine pump is basically a centrifugal pump mounted underwater and attached by a shaft to a motor mounted above the water. The shaft usually extends down the centre of a large pipe. The water is pumped up this pipe and exits directly under the motor.

Turbine pumps are very efficient and are used primarily for larger pump applications. Often they consist of multiple stages, each stage is essentially another pump stacked on top of the one below. It works like a train with multiple engines hitched together pulling it, each stage would be an engine. When a huge motor is seen mounted on its end and a pipe coming out sideways below the motor that is most likely the motor for a turbine pump down inside the well.

 

A jet pump is similar to a turbine pump but it works by redirecting water back down to the intake to help lift the water.
