Oil Sealed Vacuum Pump

Some of the features which ensure protection of oil sealed vacuum pump as well as trouble free running are described below. Gas BallastIt allows atmospheric air or an inert dry gas to be admitted to the oil vacuum pump before compression stage. This prevents condensation thereby preventing the degradation of oil. Air admittance Valve It is a solenoid operated pneumatic valve which allows air into the system during sudden power outage thus preventing the reverse flow of the oil. Non-return Valve It is a spring loaded diaphragm type valve. This prevents reverse flow of oil during stoppage of the pump. Moisture trap Presence of moisture affects the pump performance in an adverse manner and it also results into contamination of oil. The trap is therefore provided at the inlet port to remove the moisture present in the air. Inlet Dust Filter The working chamber components of oil sealed vacuum pumps like rotor, stator, and side plates are machined with very precise tolerances and during operation they run with very fine tolerance. It is therefore mandatory to prevent entry of dust/solid matter particles into the pump. Thus the in-line inlet filter ensures a particle free inflow of air/gas into the system. Vacuum Gauge A suitable gauge compatible with operating environment, measurement range and scale can be supplied. It can be provide with a regulator if required. Trolley Oil Sealed Vacuum Pump gives portability to the pump. Generally preferred for smaller pumps.
