Enhance the longevity and efficiency of your downhole equipment with the Evolution Anti-Vibration Centralizer (AVC). Specifically designed to run alongside the tubing string, this centralizer keeps the tubing centered, preventing premature wear on both the casing and tubing.

Key Benefits

• Reduced Vibration: Effectively minimizes harmonics and vibrations caused by the downhole PCP, extending the life of your equipment.
• Enhanced Centralization: Keeps the top of the PCP pump and the production string centered during installation and production, ensuring optimal performance.
• Increased Production: Safety allows for higher PCP pump speeds, boosting overall production rates.
• Durability: Features a full tubing drift and high bypass, ensuring smooth operations and reduced wear on all downhole tools.

Evolution’s Rotating Anti-Vibration Centralizer (RAVC) is specifically designed to reduce PCP harmonic vibrations while using a surface tubing rotator, helping operators maximize production and equipment life.

Key Benefits

• Safely allows increased PCP speed to boost production.
• Reduces harmful downhole vibrations.
• Maintains tubing rotation during operation.
• High bypass capacity for optimized flow.

Increase the rigidity of your PC Pump with CAVS to dramatically reduce vibrations

• Dangerous vibrations are caused by operating near the natural frequency of the pump system or any of its harmonics. These vibrations lead to tubing breaks resulting in costly workover, tubing replacement and lost production.
• Evolution has developed technology to eliminate the majority of vibration at the pump by firmly supporting the stator against the casing using the new CAVS.
• Evolution can calculate the natural frequency of a pumping system to determine the number of CAVS required on the pump to ensure the natural frequency is above the maximum rod speed (500 rpm as default). Pump OD, ID and length are required.

The Evolution Rod Vibration Stabilizer is a device that centers a
rotating rod string within the tubing string to reduce rod breaks
and prevent wear. It works by keeping the rod firmly centralized
and letting a pony rod betweeen the Rod Vibration Stabilizer and
the rotor flex to allow for the the eccentric motion of the rotor
tubing, minimizes friction, and extends the life of the rod string
and other equipment.

Key Features
• Reduce rod string breakage and workovers.
• Limits vibration in the rod string due to eccentric motion of the rotor.
• Installed with Evolution Anti-back off™ Coupling

The Evolution Anti-back off ™ Coupling is engineered to minimize
polished rod back-off and improve connection integrity in high
speed, high torque PCP pumping applications. Designed for easy
field installation, the Evolution Anti-back off Coupling provides
enhanced resistance to polished rod connection back-off if a rod
breaks downhole.

Key Benefits
• Prevents the rod string momentum from backing off the
polished rod if rod break occurs downhole.
• Offers 50% more unscrewing torque (back-off torque)
compared to conventional polished rod couplings.
• Strengthens the connection at the polished rod.
• Enhances the rod reliability in demanding operating conditions.
• Simple and efficient field assembly.
