The Ellis JMAX 1-piece patented insert cage gives unparallel compression ratio and no-restriction fluid flow compared to any cage*. The cage is engineered to reduce ball rattle and provide zero-restriction flow without reducing wall thickness. It has been designed to perform in horizontal wells also. The high compression ratio and no-restriction flow makes it suitable for gassy and sandy environments. The cage also reduces the ball rattle up to 43% and the pressure drop up to 69% as the fluid flows through the cage when compared to other cages. Excessive ball rattle can beat out a cage causing premature failure. Reduced pressure drop results in lesser gas breakout into the pump intake. The Ellis JMAX Cages are available in traveling valve, standing valve and double valve configurations with high performance materials for corrosive environments.

Ellis Manufacturing has developed an in-house flow loop to test the performance of diverse types of cages currently used in the sucker rod pump industry. A comparative study was performed between the JMAX Cage and 8 other cages from different manufacturers. The data revealed less ball rattle and lower pressure drop consistently at different flow rates without compromising on pressure rating.  

High quality machining processes adopted at Ellis Manufacturing allows to maintain extremely close tolerances and produce components with smooth surface finished and chatter free threads.
