The spring is typically located around a central shaft that is attached to the closing disk. The entire assembly is securely enclosed in a machined brass housing that contains the workings of the check valve. The check valve is generally located above the submersible pump unit by a few inches. This ensures that the long column of water remains in the well pipe. This increases the efficiency of the pump by not having to refill the length of the pipe every time the system calls for water.
A. Inside the nose of a shallow well jet pump there is a nozzle and venturi pair. The nozzle blows water through the venturi which creates a pressure differential. Itâs this pressure differential that actually helps the pump build pressure. Itâs kind of the same physics principal used in a jet engine. shallow well jet pump has the nozzle & venturi of the jet system built into the nose of the pump. In a deep well jet pump setup, the nozzle & venturi are put into an ejector package or âjet kitâ that gets placed down in the well.
