Deep Well Jet Pump Installation

Deep well jet pump single pipe step 1 make sure the well is pumped clean and that sand and grit are absent.

Deep well jet pump installation.

A jet pump performs best when installed close to the well because suction lift and friction losses are kept to a minimum. Jet pumps which are primarily used for shallow wells less than 25 feet deep should be placed in a well housing and then mounted above the well in a separate well house or other structure. For deep well installation the drive line is 1. If you use pvc pipe connect the.

Step 2 deep well pumps are always installed with the ejectors or jet attached to the bottom of the suction pipe in the well. Run pipe between the pump outlet and tank inlet connecting it with appropriate fittings. Jet pumps for shallow wells move water by creating a vacuum. To prevent overpumping the well a deep well jet pump.

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. 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. The tank should also be located as close to the pump as possible to avoid excessive pressure and friction losses.

A foot valve must be used if the ejector or jet does not have a built in check valve. The shallow well jet pumps draw water from one line situated in wells no deeper than a maximum of 25 feet deep. Jet pumps usually come with a 30 50 pressure switch factory installed on the pump. If replacing the switch we recommend using one with a 30 5 psi setting.

Do not reduce the sizes of pipe.
