ABSTRACT:
The present invention relates to improvements on an "inertia" type pumping system (actually using kinetic energy) including elimination of springs in the valves, include pressure dampening or cushioning means for dampening sharp liquid pressure rises inherent in an inertia type pump, and discharge of pumped fluid directly into a tank rather than through a circulation pump of the system, all of which results in longer pump life, less down time for repairs, smoother, quieter and more efficient operation, and avoids shutdown of the inertia pumping system by eliminating gas entering the circulation pump when pumping oil having entrained gas from a formation.
