一、Features: 
1. The machine pump is designed with a coaxial design, which saves space, which is easy to install and convenient for maintenance.
2. All imported mechanical seals are used as standard equipment.
3. All items provided with a cavitation protection tube interface, such as operating at extreme pressure, open the etch protection tube interface (or connected to the separator) to eliminate the cavitation noise with maximum guarantee of the aspiratory effect and protect the pump.
4.2 BEV full series standard with stainless steel impeller, 2BV2 series all with stainless steel disc/impeller. It's strong, durable, and enhances the corrosive of the pump. If the flow components are all made of stainless steel, they can work in a more demanding condition.
5. Unique flexible exhaust port design, which does not produce over-compression, ensures the best efficiency of 2BV within its performance range.
6. All items use the Y2 series motors with the protection grade of IP54 and IP55 (common is IP44) and the insulation grade of F (common is B).
7. All items use SKF or NSK imported bearings
8.2BEV series liquid ring vacuum pumps can realize that all flexible seals are Teflon, which can greatly extend the service life of the vacuum pump under harsh conditions.
