Continuous Flow Plungers

Continuous flow plungers, also known as bypass plungers, have a bypass valve that opens up the flow area through the center of the plunger that allows the flowing well to produce as the plunger is falling to the Bottom Hole Assembly (BHA). Once the plunger arrives at the BHA, either a dart valve closes or a ball is mated with a sleeve to create a positive seal or ascent position. The plunger cycles to the surface removing the liquids in the tubing string. This plunger method produces more cycles per day, delivering continuous fluid removal and optimizing high-rate wells to their maximum potential.

Our Bypass Plunger Technology provides the lowest cost of ownership with proven production enhancement in high rate oil and gas wells.

Our bypass plungers are engineered to perform in extreme cycling conditions that are required in high-rate flowing wells. Our patented design incorporates the industry’s first unibody dart bypass body and clutch system that will continue to operate so operators achieve maximum wear. There are no welds or pins that cause premature wear or breakage on traditional designed plungers.

A ball and sleeve is a two-part plunger. When the sleeve reaches the bottom hole bumper spring, it joins the ball and forms a seal. Differential pressure in the well allows the plunger to ascend to surface removing accumulated fluids. A separator rod in the lubricator unseats the ball and repeats the process after the journey to the top.

The sliding sleeve plunger is a center no-shift rod style bypass plunger that requires very little off time and no rod in the lubricator. These plungers are port adjustable/flexible. The port selection varies based on the well’s production rates. You can plug a port as the well’s production changes. These plungers typically show good performance in wells operating under critical velocity.
