High Vacuum Pumps These are of oil-immersed, rotary vane type pumps. The rotor, with two spring loaded vanes, is mounted eccentric in the stator body, As the rotor, rotated the vanes sweep the crescent shape valve which prevents back flow of air.
Manufactured from graded material, all moving parts are precisely machined, ground and assembled with close tolerances. This results in increased efficiency and long trouble free operating life.
Accessories
Air admittance Valve
It is electromagnetic solenoid type which admits air into the system as soon as the power supply fails. This prevents back flow of oil to the the system.
Air Ballast
This a vent pipe introducing air before actual compressions which eliminated condensation of the sucked vapor. There by 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 pump stops. These can not be used to hold the vacuum in the system for longer period.
