Pumps:
The hydraulic machines, which convert the mechanical energy into hydraulic
energy, are called pumps. The hydraulic energy is in the form of pressure
energy and flow. A pump is a device used to move fluids, such as liquids, gases
or slurries.
Classification
of Centrifugal pump on the basis of flow:
-
Radial flow pump: Used for high pressure or High head.
-
Mixed flow pump: Used for medium flow & medium head/ pressure.
- Axial flow pump: Used for high
flow and low pressure.
Classification
of Centrifugal pumps on the basis of:
Types
of casing: (a)Volute casing
(b) Vortex or Whirlpool casing.
(c) Diffuser vane casing.
Types
of stage: (a) Single stage.
(b) Multistage
