Centrifugal Pumps
Most used pumps in engineering because they support wide range of heights and flow rates. Mixed flow, rotodynamic pump.
There can be a diffuser as well, which is optional.
Volute
Casing of the impeller. A passage with increasing area, to reduce velocity (to reduce losses).
Diffuser
A fixed set of vanes added to the impeller. To direct the flow into the volute, to minimize impact losses.
Operation
- Volute must be filled with fluid to start pumping
- Fluid enters through the eye of the impeller
and are increased when the fluid flows through the impeller
