Pumps can be classified based on their casings as follows: volute casing, axial split casing, and radial split casing.

• Volute casing pumps have a spiral-shaped casing that gradually expands to the discharge outlet.

• Axial split casing pumps have a casing split along the horizontal centerline of the pump.

• Radial split casing pumps have a casing split along the vertical centerline of the pump.

Air compressor works by compressing air to increase its pressure and decrease its volume.

• Air is drawn into the compressor through an intake valve.

• The air is then compressed using a piston or rotating impeller.

• Compressed air is stored in a tank or released directly for use.

• Examples of air compressors include reciprocating, rotary screw, and centrifugal compressors.
