pump for deep well

Brief Introduction:

The pump for deep well conforms API Spec 11AX specification. The hanging depth of Deep well pump is increased by 500-1500 m compared to the conventional whole barrel oil pump.

The pump barrel is fixed at the bottom and suspended at the top, which greatly improves the stress condition of the pump barrel.

 

The wall thickness of pump barrel is larger than conventional pump which improves the pump barrel strength.

 

Special valve cover is adopted to ensure the reliability of the plunger.

 

Special materials are used for key parts which improves reliability and service life in deep well.
