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.
