What is a
Progressive Cavity Pump ?
Progressive cavity pump is a type of positive displacement pump, which is a rotary positive displacement pump;
It was invented by the French engineer MoiNeau, and first produced by the French PCM Pump Company, so it is also called Mono pump, PC pump or PCM pump;
It has been officially named as single screw pump (单螺杆泵) or eccentric screw pump (偏心螺杆泵) in China;
Because of its high process reliability and suction capability, it is usually used for continuous, gentle conveying and precise feeding;
The stator and the rotor, driven by an external power source, mesh with each other to form a sealed cavity that separates the suction cavity and the discharge cavity, thereby generating volume changes to achieve the purpose of liquid delivery;
Progressive Cavity Pumps Working Principle
The progressive cavity pump is a kind of internal meshing closed rotor positive displacement pump. Its main working parts are composed of an eccentric screw (rotor) and a fixed elastic bushing (stator).
The rotor is a screw with a large lead, a large tooth height and a small thread inner diameter, while the stator is an elastic bushing with a double-ended spiral.
Due to the special geometric shapes of the stator and the rotor, they will form several separate sealed cavities that are not connected to each other.
When the rotor is running in the stator, the sealed cavity moves in the axial direction from the suction end to the discharge end of the pump.
The medium is continuously and uniformly conveyed in the coaxial line from the suction side to the pressure side without changing the volume.
