Progressive cavity pump
Stator type from standard wall thickness to uniform wall thickness (spiral), materials including NBR，FKM and other kinds of high quality rubber. According to the pumping medium provided by the user, the adaptability test can be carried out to select the best rubber material.
Progressive Cavity Pump
The rotor is manufactured by a CNC machining center, which can provide standard materials such as hard tool steel 1.2436 and stainless steel 1.4571, and other materials can also be provided according to customer requirements. Depending on the temperature of the conveying medium, the size of the rotor will also be slightly adjusted to compensate the influence of temperature to ensure the best use effect. In order to improve the life of the rotor under the condition of abrasive medium transportation, the rotor surface can be coated in various forms, such as hard chromium plating or carbide (such as tungsten carbide, etc.), the surface hardness can reach more than 65HRC.
