API Wheeled Sucker Rod Centralizer and Sucker Rod Guide
Sucker rod centralizer, or sucker rod guide, used in pumping well, is a tool protecting sucker rod from wiping with tubing pipe. It consists of coupling, centralizer sleeve and sub.
Sucker rod centralizer is used to centralize the lifting rod in beam pumps and the rotating rod in progressive cavity down hole artificial lift pumps. By centralizing the rod, the guide acts as a wear resistant bushing, preventing the rod from wearing through the production tubing. Rod and production tubing contact is increased in deviated wells and horizontally drilled unconventional shale wells.
Size: 5/8", 3/4", 7/8", 1", 1-1/8", or others as required
Type: wheel centralizer, rod shaped centralizer, twist centralizer.

2) Rod shaped centralizer: When sucker rod works, nylon block touches tubing
inside, it can avoid sucker rod rubbing with tubing pipe. Nylon block can rotate,
then the rub is even wear. The user only change nylon block replace rod body, which
reduces fabrication-cost;
3) Twist centralizer: Low cost, easily operated.
