product description

FTQ centralizer rope damper is new device wi4 anti-eccentric, anti-trip, paraffin cutting, and oil increment which can prevent the sucker rod from trip and extend serve life.

Structure principle: elbow method and integral bearing stem. The centralizer adopts special nylon 66 material and one~time molding technology. Nylon centralizer has spiral groove following the axial direction, which is moved by liquid flow. The free rotation of center pole can eliminate the spiral curve torque made by sucker rod drain； extend service life, and lower production cost.
