Ultra-Duty Bumper Springs

Flowco manufactures the only patented one-piece fishing neck/mandrel-designed bumper spring on the market.

Our ultra-duty bumper springs are engineered to withstand the constant cycles of all bypass plunger types. The traditional bumper spring designs involve pinned fishing necks which deteriorate from repeated impacts, loosen, and cause operator’s production downtime with the added expense of a slickline job. The Flowco bumper spring assembly is designed with a proprietary spring to achieve optimal cushion and recoil for maximizing the life of the complete bumper spring.

These innovative features, combined with our patented fastening method, reassure operators that you have acquired the toughest bumper spring assembly available.
