Vacuum Pump – Oil Sealed Rotary High Vacuum Pumps, Compression

Twin Lobe Roots Blowers and Exhausters, Tri Lobe Roots Blowers and Exhausters, Pneumatic conveying systems, Mechanical Vacuum Boosters and complete Systems, Catalyst Unloading Systems, Dust Collection Systems, etc.

Oil Sealed Rotary High Vacuum Pumps

These are oil immersed rotary vane type pumps The rotor with two spring loaded vanes is mounted eccentrically in the stator .As the rotor rotates, the vanes sweep crescent shaped air space twice in each revolution .The built-in non return valve prevents back flow of air.

ACCESSORIES

Air admittance Valve:
It is electromagnetic solenoid type which admits air into the system as soon as the power supply fails . This prevents backflow of oil to the system.

Air Ballast:
This is a vent pipe introducing air before actual compressions which eliminates condensation of the sucked vapor , thereby avoiding contamination of oil.

Non –Return Valve:
It is rubber diaphragm type spring loaded valve ,which prevents back-flow of oil to the system as soon as the pump stops. These can not be used to hold the vacuum in the system for longer period.
