Chemvak A series are chemical resistant vacuum diaphragm pumps which can be used in the chemical, pharmaceutical, petrochemical and other industries, such as suction filtration, vacuum distillation, rotational evaporation, vacuum concentration, centrifugal concentration, solid phase extraction and so on. Chemical resistant vacuum diaphragm pumps can be widely used to hard acidic, basic and solvent vapors by utilizing corrosion proof PTFE on all the wetted surfaces. The vacuum chamber and the drive chamber are separated and sealed, Ensure a longer working life of mechanical components Chemvak A series pumps are driven by Diaphragm, without the need of lubricant, regular oil changes and maintenance; with no oil pollution.
Driven direct by motor with no additional belt-driven transmission; the quality vibration-proof assembly makes Chemvak A series run at the lowest noise level among all other equivalent pumps.
Cost-effective, reliable, unique structural design, noise less than 50dB. A variety of models are available to meet the various needs of the laboratory, with a minimum vacuum of up to 2 mbar. Every motor of Chemvak A series pumps has a built-in thermal protection device to shut off the pump automatically when overheated and then resume working when the temperature cools down.
Also view our Chemvak C series chemical resistant, diaphragm vacuum pumps which can be widely used to remove acidic, basic and solvent vapors by utilizing corrosion proof PTFE on all the wetted surfaces. Through innovative mechanical technology and human consideration, Chemvak C series diaphragm vacuum pumps are designed to be quiet, safe, maintenance-free and cost effective vacuum pumps.
