Application prospect of progressve cavity pump with uniform-thickness esastomer stator

In order to improve the service performance and to enhance the system efficiency of the conventional progressive cavity pump, a progressive cavity pump with uniform-thickness elastomer stator is developed. Research and application of this pump at home and abroad shows that, it has the following advantages compared with the conventional pump: (1) high thermal diffusivity improving the service life of the pump; (2) uniform rubber expansion improving the stability of the pump in operation; (3) high pressure bearing capacity improving the system efficiency; (4) high pump efficiency reducing production cost. The key technique of this kind of pump lies in the machining technology and welding of the stator barrel.
