Then the oil can be lifted to the ground along the oil tube. Our sucker rod pumps are according to the API standard. We can also manufacture long plunger pumps and suspension pumps etc. as requested by the client.

TR’s new designed swivel and rigid sucker rod couplings provides around 1” off-center deflection, as picture. This transmits the effective mass of the sinkerbars through the longitudinal axis of the string to greatly enhance overall pump efficiency. This deflection also minimizes the “binding effect” of straight-coupled sinkerbars in deviated wells. Mechanical and fluid friction has been a substantial problem in pumping system design throughout the years. The only answer until now has simply been to overcome this resistance by using brute force. The swivel connection offers an alternative method for this situation.

In addition to the swiveling couplings, our rigid couplings are specifically engineered to reduce frictional drag factors to maximize downhole pump stroke and enhance overall artificial-lift system capabilities. Both couplings provide standoff clearance which acts as a journal-bearing surface for the lower string. This greatly reduces the friction contact areas between rods, sinkerbars and internal tubing walls.

Time Rolling's sucker rods advanced continuous upsetting automatic production line is from Russia origin. Our sucker rods are high strength. They 100% pass the rod head fluorescent magnetic particle testing. The maximum output of our sucker rod factory can be 5 million meters/year.
