The new indigenous diaphragm pumps features improved performance data and superior vapor tolerance. Diaphragms have especially long lives and seal the drive space from the pumping chamber to protect mechanical parts from corrosion.
Our diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors. Chemically resistant and eco-friendly diaphragm pumps are resistant to aggressive solvents and acidic vapors which make them a handy product to use in chemically rich environments.
The diaphragm pumps achieve distinctively high performance compared to other types of pumps because of high pumping chamber volume relative to the minimal dead space. The lack of abrasion also eliminates most particulate impurities that are frequently generated inside of other types of pumps such as scroll or piston pumps.
The two-stage construction provides an advantageous combination of high pumping speed and low ultimate vacuum. The diaphragms and gas contacting parts consist of PTFE, PTFE Compounds, and ceramic compounds. Well-proven PTFE sandwich diaphragms are used for increased reliability and extended operating life. The vacuum processes run more effective and is reproducible. The additional pressure reduction allows the distillation of gas mixtures almost automatically and without fractionated operation.
