China Sucker Rod - Manufacturers & Suppliers‎

We offer high quality sucker rods, couplings and accessories with improved resistance for beam and progressive cavity pumping, as well as full technical support services. With 45 years experience and production facilities in China, Argentina, Brazil, Mexico and Romania, we support artificial lift operations worldwide. Our new mill under construction in the US brings our production capacity to over 5 million units further expanding our global reach.

Linked rods attached to an underground pump are connected to the surface unit. The linked rods are normally called sucker rods and are usually long steel rods, from 5/8 to more than 1 or 1 1/4 in. in diameter. The steel rods are normally screwed together in 25- or 30-ft lengths; however, rods could be welded into one piece that would become a continuous length from the surface to the downhole pump. The steel sucker rods typically fit inside the tubing and are stroked up and down by the surface-pumping unit. This activates the downhole, positive-displacement pump at the bottom of the well. Each time the rods and pumps are stroked, a volume of produced fluid is lifted through the sucker-rod tubing annulus and discharged at the surface.
