Submersible Well Pumps deliver the water from your well to your tap. Shallow well jet pumps are used for wells under 25 feet deep and have no working parts submerged in water. On the other hand, deep well jet pumps can be used for wells up to 75 feet deep and have their ejectors installed in the well itself. Submersible well pumps are used underwater in wells. A small electric motor (called a driver) is installed in the well shaft, usually below the pump itself, and an electric cable is attached to the motor. Piping is then fitted from the pump, through the length of the shaft, and into the home. Unlike their shallow-end counterparts, submersible well pumps may be set hundreds of feet beneath the water in a well. When the pump is activated, the motor, consisting of several impellers and diffusers, spins on a common shaft (called stages), and pushes the water out of the well.
