Deep Well Jet Pump Installation

To prevent overpumping the well a deep well jet pump.

Deep well jet pump installation.

For deep well installation the drive line is 1. Unlike submersible pumps they must be primed with water before they can draw the water. Deep well jet pumps use two lines one for pulling the water and one for pushing the. Jet pumps usually come with a 30 50 pressure switch factory installed on the pump.

Deep well jet pump single pipe step 1 make sure the well is pumped clean and that sand and grit are absent. Step 2 deep well pumps are always installed with the ejectors or jet attached to the bottom of the suction pipe in the well. Screw an adapter to the threaded pump outlet and tighten it with a wrench. Jet pumps for shallow wells move water by creating a vacuum.

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. A foot valve must be used if the ejector or jet does not have a built in check valve. If replacing the switch we recommend using one with a 30 5 psi setting. If you use pvc pipe connect the.

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 tank should also be located as close to the pump as possible to avoid excessive pressure and friction losses. Run pipe between the pump outlet and tank inlet connecting it with appropriate fittings. Do not reduce the sizes of pipe.

A jet pump performs best when installed close to the well because suction lift and friction losses are kept to a minimum.
