Features

1、It has all features and functions of conventional PC pump.

2、It can be used in sandy well sand percentage of which is 60%.

3、It performs perfectly in oil extraction wells sand percentage of which is no more

    than 15%.

4、In stator abrasive rubber is used; the design of stator structure can improve 

     the abrasive resistance.

5、 In rotor hard alloy is used, and the surface is hardened in order to increase abrasive resistance and the service life. Taking into consideration anti-sand qualities of the structure, the end of rotor is provided with off-center design.

6、To meet the needs of anti-sand qualities of the pump, rotor and stator are matched according to the reasonable interference magnitude.
