Pumps are devices used to move fluids by mechanical action. There are various types of pumps such as centrifugal, reciprocating, and rotary pumps.

• Centrifugal pumps work by converting rotational kinetic energy into hydrodynamic energy to move fluid.

• Reciprocating pumps use a piston or diaphragm to displace fluid in a back-and-forth motion.

• Rotary pumps operate by trapping fluid between rotating components and the pump cas...read more
