The Evolution AVS – Anti-Vibration Sub is designed to be run with the tubing string to keep the tubing centralized preventing premature wear of the casing and tubing. The AVS also helps reduce the harmonics and vibrations caused by the PC Pump, potentially reducing premature wear of the tubing anchor, rod string, and other downhole tools.
Applications
- Used in cases where PC Pumps create vibrations in the casing
- Keeps the production string centralized during installation and production
- Centralizes top and bottom of the PC Pump
- Gives the option to safely increase PC Pump speed, in order to increase productionUsed in tubing rotators applications
Unique Features
- High bypass capacity
- Full tubing drift
- Robust Design
