WELL PUMPING SYSTEM CONSTRUCTION |
摘要 |
A well pumping system construction having top and bottom seals spaced within a well casing or well shaft forming a combination water storage and air pressure tank chamber therein. A water delivery pipe communicates with and extends through the tank chamber and is connected at the lower end to a pump and is connected at the upper end to a water supply line above the well casing. Pump controls are located at top of the delivery pipe above the well casing and are enclosed by a protective housing. A conduit within the well casing provides the means for inflating the bottom seal, provides a well breather passage, and contains the electrical wires for the pump.
