Deep Well Jet Pump Installation

To prevent overpumping the well a deep well jet pump.

Deep well jet pump installation.

If you use pvc pipe connect the. Jet pumps for shallow wells move water by creating a vacuum. Convertible jet pumps like the red lion rjc 100 shown at above left that can be swapped between a shallow well typically from 25 ft one line jet pump to a deep well two line jet pump are typically capable of lifting in the 2 line jet pump conversion from a depth of about 90 feet. The shallow well jet pumps draw water from one line situated in wells no deeper than a maximum of 25 feet deep.

For deep well installation the drive line is 1. A foot valve must be used if the ejector or jet does not have a built in check valve.

Jet pumps usually come with a 30 50 pressure switch factory installed on the pump. A jet pump performs best when installed close to the well because suction lift and friction losses are kept to a minimum.

The tank should also be located as close to the pump as possible to avoid excessive pressure and friction losses. Unlike submersible pumps they must be primed with water before they can draw the water. Run pipe between the pump outlet and tank inlet connecting it with appropriate fittings. Deep well jet systems are used when the water depth is between 20 and 80.

Deep well jet pumps use both the suction at the jet to bring water into the system and pressure applied by the impeller to lift the water.
