The Submersible Centrifugal Pump

The number of pump stages is determined by the required lift. Each stage consists of a floating impeller connected to the Monel-k500 drive shaft and a stationary diffuser directing the flow of the fluid. The impeller axial force is made of wear-resistant material. In order to reduce axial force, the structure of impeller and diffuser is designed by floating type. The rest axial load and pump shaft deadweight are hold by protector thrust bearing.

The characteristics of centrifugal pump is as follows:

• Principal whole floating type, it can eliminate effect that axial force acts at centrifugal pump, extend the life of electric submersible pump.

• Leaf material using nickel-iron pulley, with a strong wear resistance and corrosion resistance.

• The special technology design of impeller and diffuser makes the centrifugal pump fit all kinds of producing well (include viscous crude) and it has high efficiency as well as good result of sand prevention.

• The built-in strong magnetic scale remover in centrifugal pump according to user demand, it can effectively prevent scale from depositing in pump.
