What is A Progressive Cavity Pump?
Progressive Cavity Pump is a type of positive displacement pump which has a rotor rotating within a housing called a stator. The rotor is always metallic and the stator is made up of a rubber type of material. It looks somewhat like a screw thread–the fluid is between the cavities and the rotary motion of the rotor forces the fluid through from one end to the other. The liquid acts as the lubricant between the pumping elements, and it should not be run dry.

Mingzhu's progressive cavity pump belongs to the group of rotating positive displacement pumps. They are self-priming, and due to their high process liability and suction capacity. They are often used for the continuous, gentle conveyance and precise dosing - in proportion to speed - of difficult media.

The Main Advantages of Progressive Cavity Pumps：
* Space-saving design and low maintenance costs.

* Strong wear resistance (adjustable structure) no leakage, energy saving. You can save more costs.

* It is suitable for conveying all kinds of medium with fluidity, non-fluidity, high viscosity, high concentration, strong corrosion, strong solubility and strong wear.

* No irrigation and water diversion, strong self-priming capacity, small vibration, low noise, constant reverse performance, long service life.

* Widely applications in petroleum, chemical industry, environmental protection, medicine, brewing and other industries.

* Progressive cavity pump is a simple structure so that you can easily operate and maintain it.
