Application:
This series if used for pumping air Insoluble in water, containing no solid particles, non-corrosive.
This pump adopts bronze impeller and air distributing plate, so vacuum pump intensity is higher than other pumps. If used for pumping corrosive air, steam or liquids, anti-corrosive material must be selected, and users must notify us when make order.
Working Principle:
Impeller is installed eccentrically in the pump. When it rotates, liquid form a spinning ring at the inner wall of pump body. Clearance between impeller transverse and distributor is sealed by liquid. At the beginning of the rotation (through air inlet hole), impeller sealed capacity is gradually reduced, air is exhausted and finish one exhaust process. To keep constant water ring, continuous water feeding to the pump is a must during operation.
