Chinese screw pump manufacturers produce three-screw pumps, twin-screw pumps, and multiphase pumps.

Advantages:

? Integral Rotor Design No Metal Contact Between Rotors ? 

? No Power Transmission Between Rotors Low Maintenance Costs ? 

? Special Profile Design Optimal NPHSr ? 

? No Axial Forces Excellent Self-priming 

? Full Recirculation Pressure-Limiting Valve Possible 

? Multiphase Pumping Structure  Possible

Application:

This product series is designed to address different fluid  environments with low,medium and high pressure models.  They are widely used in the high-flow, long- distance  transportation of oilfield gathering systems, effectively  handling high-water, high GVF% content and high-viscosity  medium. In some cases, they can serve as alternatives to  certain pipeline pigging functions, reducing operational  pressure.
