FAQ
Is a progressive cavity pump the same as a screw pump?
No, it’s not.
The progressive cavity pump is a positive displacement pump. It has only one screw rotor, which has slight interference fit with the rubber stator. Screw pumps also need at least two screw rotors to cooperate, and usually there are three or five screw rotors to cooperate. The name is also named after the number of screw rotors. For example, a pump with two screw rotors is called a twin screw pump.
What is a progressive cavity pump used for ?
The biggest characteristic of progressive cavity pump is that it is especially suitable for conveying sensitive liquids which cannot be sheared, squeezed or stirred, that is, non-Newtonian liquids which will show thixotropic properties when subjected to shearing. It is not only suitable for transporting medium with low viscosity such as water, but also especially suitable for transporting suspension containing solid particles or short fibers and medium with very high viscosity.
How does a progressive cavity pump work ?
The main working parts of progressive cavity pump are stator and rotor. Because of the special geometric shape of stator and rotor, when assembled together, several separate sealing cavities will be formed. When the motor drives the rotor to move, the medium in each sealing cavity will be continuously and uniformly transported from the suction end to the extrusion end with constant volume.
How do I choose a progressive cavity pump?
It needs to be selected according to the physical and chemical properties of the conveyed medium in the current application;
Key technical factors:
- Pump displacement
- Pressure or conveying distance (including horizontal and vertical distance and number of elbows)It needs to be selected according to the physical and chemical properties of the conveyed medium in the current application
