Classify different types of pumps.
Identify the components of a centrifugal pump.
The two main forms are positive displacement type and centrifugal pumps.
In positive displacement type, the volume of liquid delivered is directly related to the displacement of the piston and therefore increases directly with speed and is not appreciably influenced by the pressure.
e.g. reciprocating piston pump and the rotary gear pump
The centrifugal type depends on giving the liquid a high kinetic energy which is then converted as efficiently as possible into pressure energy.
Centrifugal pump converts the mechanical energy into pressure energy by means of centrifugal force acting on fluid, which rises water or liquid from a lower level to higher level. The main components of a centrifugal pump are:
Suction pipe with a foot valve and a strainer
Which of the following pump is generally used to pump highly viscous fluid?
In a centrifugal pump, the liquid enters the pump:
A centrifugal pump is superior to a reciprocating pump because:
