Abstract:
1. An assembly for pumping fluids in a well comprising: a pump comprising a pump barrel having an upper end and a lower end and a pump element selected from a plunger or a rotor mounted in said barrel, said pump element having an elongated moveable rod extending therefrom; a seal cartridge positioned about said elongated moveable rod for inhibiting fluid flow along said rod in either axial direction; an outlet housing connecting the pump barrel with the seal cartridge, said outlet housing defining at least one laterally facing fluid outlet; a fluid flow tube housing positioned radially outwardly from the barrel and the outlet housing, an annulus being formed between the fluid flow tube housing, the barrel, and the outlet housing; said at least one laterally facing fluid outlet opening into the annulus; and a barrel manifold seal coupling forming intake openings from an outside of the barrel manifold sealing coupling to a bottom of the pump barrel and a passage for discharging fluid downwardly from the annulus, wherein the fluid flow tube housing encloses the barrel manifold seal coupling and the seal cartridge so that actuation of the pump draws fluid through the intake openings and discharges fluid through the passage for discharging fluid from the annulus.
