Lubricator/CatcherThis piece of equipment is installed at the wellhead and catches the plunger upon its arrival at the surface. It is designed to allow gas-flow passage even when the plunger is in the lubricator. Available in a variety of sizes and in special materials of construction for severe-service operations.

Inductive SensorsThese sensors are mounted to the wellhead to detect plunger arrival, which lets the operator more easily monitor applications where plunger detection is difficult or unreliable. After strap-on installation, it uses the controllers power supply for operation and its sensitivity can be adjusted to gain an optimum signal.

Electronic ControllerIdeal for use where operators want to utilize time or pressure settings for plunger lift control and where applications have fluctuating line pressures. Uses a patented Auto-Cycle algorithm to offer multiple control modes, including plunger lift, gas-assisted plunger lift, annular flow and Plunger Enhanced Chamber Lift (PECL).

Bumper SpringsAvailable in four styles depending on well features, Ferguson Beauregard bumper-spring formulations are installed at the bottom of the well tubing and offer easy installation and low maintenance and replacement costs.

PlungersAvailable in a wide variety of designs made for the unique characteristics of individual wells, all styles of Ferguson Beauregard plungers are created to improve production rates and lower maintenance costs, which in turn save the operator time and money.
