Polished Rod Clamps
A polished rod clamp is used for fastening the polished rod on the equalizer beam of a pumpjack. The polished rod is fastened by means of tightening up the screw joint of half-bodies.
Depending on the load, single, double or triple series-connected clamps can be used.
The design of the clamp protects the polished rod surface from damage and is convenient for moving.
The screw joint must be tightened up with a torque wrench with tightening torque control.
