Shengji 1-1/4'' 2-1/4'' 2-3\/4'' sucker rod tubing pump

Product Description

Shengji 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.

Key Feature

1.Rod pump can be pulled out from the well directly.

2.Well inspection and workover is convenient.

3.Reduce the cost of pumping test.

4.Suitable for deeper well.
