 Rotary vane vacuum pump continuously pursues the highest technical standards, reaching the highest level: integrated cylinder structure and innovative oil circulation system to make it super-stable; automatic anti-suction return valve and two-shift gas town to make it have the best reliability; perfect combination of technology and aesthetics helps to become a classic.

 
We also made individual analysis of special applications such as medical industry. Due to the need to pump a large number of corrosive gases and steam, we use stainless steel springs, fluororubber oil seals and other products to upgrade to RVD-M series to ensure the reliable operation of the pump.
 
 
Features
 
Tow-Shift adjustable air ballast valve meets the different requirements of condensable steam (such as water vapor) pumped out in different processes.
 
2. Dual anti-oil and anti-suction protection ensures that the vacuum system is not polluted by oil when the pump stops running and needs to be restarted easily.
 
3. Compulsory oil circulation system consists of oil pump and constant pressure oil supply mechanism to ensure the stable operation of the pump.
 
4. It uses fewer parts and is easy to maintain and repair.
 
5. Integrated cylinder structure and pin connection are convenient, maintenance and inspection are accurate.
 
6. Stainless steel springs are used to improve corrosion resistance.
