Abstract
A deep well fluid pump which enables the pumping of fluid with much less energy which includes a power column of fluid of sufficient volume, which communicates to the under side of the lifting piston for the column of fluid to be lifted, but is isolated from said fluid to be lifted, to balance the head force of the column of fluid to be lifted, a pump means to increase the head force on the power column of fluid a sufficient amount to overcome the seal friction and pre-load spring down force of the lifting piston, so that it raises the lifting piston and thus discharges a volume of lifted fluid in a surface reservoir, and when the increase force on the power column of fluid is relieved, the pre-load spring forces the lifting piston down to reload.
