Modular top loading downhole pump with sealable exit valve and valve rod forming aperture

摘要: A method and apparatus for improving the production efficiency of a well preventing gas lock. The is downhole pump comprises barrel, reciprocating plunger body having plurality inlet valves. does not require outlet valves are positioned above barrel plunger, thus eliminating Fluids enter through and, during upstrokes forced up tubing string to surface equipment. Modularity components permits be changed as productivity fluctuates also allows more fluids with smaller casing. invention prevents lock by permitting gasses escape between sliding valve rod connected plunger. Additionally, an exit sealably engages rod, which forms aperture. During operation pump, aperture in rise string.
