Plunger Lift

Kaizen Well Solutions is the only entirely Canadian owned plunger manufacturer in Canada. We offer a variety of plungers including some of our own patented designs, all exclusively manufactured in North America.

Conventional plungers

Conventional plungers are used in lower rate wells requiring shut in or build-up pressure to lift produced fluid. Typically, the minimum GLR needed is 400 SCF per BBL per 1000 ft of well depth.

Our conventional plungers are available in pad/blade, solid and brush configurations for the following applications:


A very efficient plunger with a constant sealed design, used typically in lower volume wells and GLR wells with clean gas/water environments and minimum solids or paraffin.


A strong, simple and affordable plunger typically used in wells with lots of paraffin, asphaltene and emulsion.


Features a very efficient seal, typically used where there’s lots of frac or formation sand; not ideal for paraffin or asphaltene wells.

Free cycle plungers

Free cycle plungers have an external trip rod mounted in the lubricator and feature a large bypass area that allows plungers to fall against high flow rates. As a result, it can travel to the well bottom more quickly than conventional plungers. They typically fall 80% of critical flow rate.

Sliding sleeve plungers

On sliding sleeve plungers, the valve trip assembly is built into the plunger as compared to free cycle plungers where they’re mounted externally in the lubricator. This reduces the bypass area. They’re typically used for faster fall time, but also don’t fall against flow easily.

Available in solid or pad configurations.

Two piece plungers

Two piece plungers are good for high liquid and high rate wells in excess of 65% of the wellhead critical rate. They can also lift high volumes of fluid in excess of 200 bbl per 1 MMCF (1.1m3 per 1e3m3 of gas). They can fall at high velocity, but require specific bottom hole spring configurations.

Available in solid configurations.
