In actual use, it is inevitable that the stator will be damaged and need to be replaced. At this time, we need to learn how to disassemble the progressive cavity pump stator. The editor of Mingjie Pump organizes the following steps for everyone:
1.Inject lubricating medium or dimethyl silicone oil from the end of the stator (Material-out chamber);
2.Rotate the drive shaft or coupling clockwise 3-5 times to make the lubricating medium fill the entire cavity of the stator;
3.Loosen the four long bolts, and remove the discharge body and buttress (if the bolts are rusted, you need to spray a little rust remover);
4.Fix the stator with tooling (can be chain clamp, pipe clamp or special fixing tool);
5.One person fixes the stator and pulls it out, and one person counterclockwise discs the drive shaft or coupling to make the stator withdraw.
