Diaphragm Vacuum Pump
oil-free and whisper quiet operation, low maintenance requirements, and extended service life.
Diaphragm pumps operate fully oil-free and do not have any sliding components in the gas path. During normal operation, they are completely free of abrasion. Contamination of the vacuum process due to particle generation, which is often encountered in the case of scroll pumps, is largely avoided.

Thanks to Google, we found the Maisi company online and bought a suitable Diaphragm Vacuum Pump for our customers at a lower price than others. This allowed us to expand our business within two years.
