Air is forced through the inlet opening (A) retracted when the impeller (E) the air in the blade channels (f) pulls centrifugally outwards and at the edge of the impeller (C) exit. The air flowing in through the intake port, upon entering the vane passages (f) is diverted from an axial to a radial direction, after which it flows outwards into the volute casing (D). In this process, the velocity of the air before it exits through the outlet (B) occurs, decelerates and converts part of the velocity energy into pressure energy. The pump runs through this process vibration free with low noise development.Pump housing and impellers are off solid cast light metal manufactured.
* This description does not reflect each manufacturer's approach to the technology, but represents a general description that attempts to include the basic operating principle.
