A pump for drawing up a liquid by meansA pump for drawing up a liquid by means
of suction produced by a piston drawnof suction produced by a piston drawn
through a cylinder.through a cylinder.
Force mode pump:Force mode pump:

used to raise a liquid or expel it underused to raise a liquid or expel it under
pressure.pressure.

4. Centrifugal pump:Centrifugal pump:
A centrifugal pump may be defined as one in which an impeller rotating inside a
close fitting case draws in the liquid at the center and by virtue of centrifugal
force throws out the liquid through an opening.
