ANDAND FORCE MODE PUMPFORCE MODE PUMP

Suction mode Suction mode pump:pump:A pump for drawing up a liquid A pump for drawing up a liquid

by means of suction produced by by means of suction produced by a piston drawn through a a piston drawn through a

cylinder.cylinder.Force mode Force mode pump:pump:A pump with a solid piston and A pump with a solid piston and

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

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.
