PUMP and Compressors - Part 1(PUMP)

What is PUMP? What is Compressor? What is different of them? So you can follow on this article. Pumps is the machine that have a function to increase up the head of fluid. Head are definite as Energy per unit weight, and have unit as the same as the long unit.

head as symbolized as h, head total of pump have three sectional of head

1. static head = z, definite as the height head. It can be count as the differential of height of suction and discharge
2. kinetics head = v²/2g
3. pressure head = P

There are many type of pump. In majority we can describe:

1. Displacement Pump, such as reciprocating and rotary pumps
   
2. Non-Displacement Pump, such as centrifugal pump, axial pump
