1. There is no metal friction surface in the pump chamber, and no spark will be generated which meets the safety requirements.
2. High rotating speed, large displacement, effective and rapid extraction of gas and other mixed gases.
3. Seal between rotating parts and fixed parts can be directly completed by water seal.
4. The temperature change of the compressed gas process in the pump chamber is very small, similar to isothermal compression; it has high safety performance for flammable and explosive gases such as gas drainage.
5. High energy efficiency, strong environmental adaptability, high operational reliability and low noise
6. Simple structure, easy operation and convenient maintenance.2 BEP 40, 0, 2 -- B, D, 3, C
