Corrosion-Resistant Vacuum Pump

Hawach vacuum diaphragm pump is designed according to the principle of volume pump. When the motor drives the connecting rod to move up and down, it drives the diaphragm to open and close, changes the volume of the diaphragm chamber, changes the pressure of the medium, and achieves inhalation and discharge.

corrosion-resistant vacuum pump

Core technology

* Teflon-treated Air chamber and air road, this makes perfect anti-corrosion ability. This model has a strong resistance to chemical corrosion resistance and organic solvent properties.
* Extremely high Ultimate Vacuum at 15mbar, this makes higher vacuum efficiency, higher efficiency than most of the pumps in the market and also higher than general Hawach pumps. It can be used with a Rotary evaporator.
* Made of imported bearings, this assured smooth operation and low noise.
* Aerospace class diaphragm makes super high durability.
* The pump made of the imported electrical power system, and automatic cooling exhaust system, ensures continuous operation 24 hours a day.
