Non-return Valve

Consists of a spring-loaded diaphragm type valve, ensuring the Oil Sealed Vacuum Pump prevents reverse oil flow during stoppage.

1

Air Admittance Valve

A solenoid-operated pneumatic valve in the Oil Sealed Vacuum Pump system allows air intake during power outages, preventing oil backflow.

2

Gas Ballast

The Oil Sealed Vacuum Pump mechanism introduces atmospheric air or inert dry gas before compression, avoiding oil degradation & maintaining efficiency.

3

Non-return Valve at Discharge Port

A built-in non-return valve at the discharge port of the Oil Sealed Vacuum Pump unit prevents backflow of air (gas), ensuring smooth performance.
