Shengji API 11AX suck rod pump with sucke rod in 5/8
Shengji API 11AX Suck Rod Pump With Sucke Rod in 5/8
Product DescriptionShengji has 40 years’ experience in designing and manufacturing subsurface pump and participated in the draw up of the national standard of subsurface pump. Shengji also developed the unconventional pump suitable for heavy oil well , high gas-cut well and high sand-cut well. Shengji deep well pump has been exported to SHELL, CHEVRON, SCHLUMBERGER, GE, NOV, JOHNCRANE, CAMERON, KBM, etc. Annual production reaches 15,000 sets.

In 1964, our factory is established;
In 1995, we bought in the first tubing production line;
In 2007, our company is restuctured;
In 2015, we became the supplier for Schlumberger and Haliburton.
