Anti-gas type screw pump mainly for the special well conditions of relatively large oil and gas, conventional rubber screw pump is easy to burn pump research and development.

1, anti-gas screw pump rotor adopts special process design, effective air carrying while draining liquid, while maintaining benign heat accumulation, avoid rubber local heat.
2, can withstand the gas-liquid ratio of more than 60%.
3. It can be matched with electric submersible screw pump, which effectively solves the problem of gas prevention of downhole screw pump without the use of flow hood.
