Wholesale Molecular Pump is a kind of vacuum pump that uses a high-speed rotating rotor to transfer momentum to gas molecules to obtain a directional speed, which is compressed and driven to the exhaust port to be pumped away by the front stage.
The conventional Wholesale Molecular Pump uses bearings to ensure the high-speed rotation of the blades. The new Wholesale Molecular Pump adopts a magnetic levitation structure, which enables the continuous increase of the blade speed, and at the same time makes the Wholesale Molecular Pump suitable for ultra-high vacuum systems, and also prolongs the service life of the Wholesale Molecular Pump.

Compared with oil-sealed rotary vane pumps and turbo-type dry pumps, Wholesale Molecular Pump has a cleaner working environment and can achieve extremely high vacuum. However, Wholesale Molecular Pump cannot work under atmospheric pressure and needs to be used in conjunction with other rough vacuum pumps (oil-sealed rotary vane pumps or turbo dry pumps) that can work under atmospheric pressure. Wholesale Molecular Pump has a complex structure and expensive price, and it will vibrate when rotating at high speed. The pumping mechanism of Wholesale Molecular Pump is different from the pumping mechanism of a mechanical pump by changing the volume of the pump chamber. It uses the principle of momentum transfer to make the molecules flow in a directional direction and be discharged out of the pump to achieve the purpose of pumping.
