How the pump cylinder works.
(This pop-up window is resizable to assist viewing)
Stainless steel cylinder (1" I.D.) is easily lowered into your well casing below static water level - along side of your existing submersible pump drop pipe (requires minimum 4 inch well casing if you have an existing pump).

Figure 1:  Pump cylinder action at rest.
Figure 2:  Upward piston action creates a vacuum and lifts
lower ball, allowing water in to the pump cylinder.
Figure 3:  Downward piston action closes lower ball and
moves water up through the piston ports into the drop pipe.
Successive up/down stroke easily lifts water to pump spigot.

Extremely simple action with precision CNC machined
stainless steel components for 50 year durability.
