▶️Common Impeller Components:
Vanes
Shrouds
Bore
Channels
Impeller Types:
Enclosed/Closed
Semi-Open
Open
Impeller Suction Types:
Single Inlet
Double Inlet
Impeller Flow Types:
Radial
Mixed
Axial
Operation
Liquid is drawn into the impeller and flows outwards away from the impeller eye. The change in cross sectional area of the impeller vanes and volute casing causes the velocity energy to be changed to pressure energy (Bernoulli’s principle).
