Rotary Vane Vacuum Pumps, Oil Lubricated

Promivac Engineers offers oil lubricated Rotary Vane Vacuum Pumps in single stage, vane type with in-built oil-circulation and anti-suck back system. The main assembly of the pump comprises of a dynamically balanced rotor with three or four specially treated fibre vanes which is mounted in a stator. When the rotor is made to rotate with the aid of the connected electric motor, these vanes move in and out of the slots by centrifugal force and slide against the walls of the stator pushing thereby the trapped air out of the stator and prompting the atmospheric air to gush in spontaneously to fill in the empty space. This continuous process happening at a high speed, gives rise to an unbreakable stream of vacuum and pressure. The oil circulation system is so designed that after providing lubrication to all the vital components of the pump, oil travels ahead without contaminating the air and gets automatically collected in its original chamber for re-circulation. Testing parameters: motor speed – 1440/2880 RPM; 220/440 V ±5%; temperature – ambient. Advantages: high pumping speed; high water-vapour tolerance; dynamically balanced rotor; built-in oil circulation system; air cooled; built-in anti-suck back system; no oil mist/fumes; low noise level; and low power consumption.
