Friendly Reminder
Users should provide accurate operating parameters:
- Flow rate – Q (m ³/h)
- Required outlet pressure or inlet/outlet pressure difference (Mpa)
- Medium conditions: including name, viscosity, solid content, specific gravity, concentration, gas-liquid ratio, working temperature of the medium, corrosiveness and abrasiveness, fluidity of the medium, etc.
- Work environment: Are there requirements for explosion-proof and insulation levels, as well as explosion-proof and protection levels.
- Installation aspects: direction of entrance and exit and other requirements.
- Requirements for product matching: whether speed regulation and speed regulation methods are required.

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;
It is mainly composed of a single-head spiral rotor (solid metal of different materials) and a double-head inner spiral stator (flexible rubber) (of course, our factory also has a double-head spiral rotor and a three-head inner spiral stator). Due to the irregular shape of the stator and the rotor, they mesh with each other to form a number of different sealed cavities, which separate the suction cavity and the discharge cavity, resulting in volume changes to achieve the purpose of liquid delivery; The stator and the rotor are interference fit, should not be run dry. The conveyed medium can act as a lubricant.
Because of its high process reliability and suction capability, it is usually used for continuous, gentle conveying and precise feeding;
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.
