ABSTRACT:
A liquid pump is provided and particularly a downhole pump for use in an oil well bore for pumping oil or in a gas well to remove condensate. The downhole pump includes a plurality of pump and transfer modules, each of which includes an elongate housing with end couplings and with two internal passages extending therethrough. The pump module further has a bladder extending between the end couplings around the internal passages with the couplings having passages connecting one of the internal passages to space on one side of the bladder. When fluid, preferably gas, under pressure is supplied to that passage, the bladder forces liquid therein upwardly into the next module. At the same time, fluid under pressure is exhausted through one of the passages from the space on the opposite side of the bladder of the next pump module, aiding it to receive liquid from the pump module therebelow. The transfer modules supply the liquid up from a lower pump module to an upper one and connect the fluid passages to enable the fluid to operate the bladders. The modules have check valves at the lower ends enabling flow of liquid only in the upward direction. However, the check valves have provisions for being opened when fluid under greater than operating pressure is applied thereto to enable liquid in the modules to drain back down through the pump.
