Sub-Surface Plunger Equipment

Multi sub-surface or ‘down hole’ springs are used to absorb the impact of a falling plunger, preventing damage to the seating device.

The sub-surface springs are made in a modular form to allow for changes of the bottom assemblies at the end of the tubing. The modular spring assembly is retrievable and supported by a sliding sleeve in the spring to protect it from damage during removal.
