Explosion-proof specifications enable tough sampling even in harsh environments!
The R series explosion-proof Dia-Vac pumps are used worldwide in hazardous environments in the oil, refinery, chemical, utility, and pharmaceutical industries. These economical and leak-free diaphragm gas sampling pumps are also an ideal choice for OEM customers and can be custom-designed to fit specific applications.
IECEx / ATEX certified explosion-proof pump can be used in environments with flammable gases. *This is not an explosion-proof certified product in Japan.
- Maximum allowable discharge pressure 12 bar (1.2 MPa) - Basic flow rate 30 l/min (50Hz) / 35 l/min (60Hz) - Corrosion-resistant specification SUS / PTFE - Robust design to withstand tough operating conditions - Leak-tight specification 6 x 10^-3 mbar x l/s
This is the smallest type of KNF diaphragm gas pump (minimum 10.8g). You can choose from five types of motors depending on the application purpose.
