Difference Between Pump and Compressor [With PDF]

The main difference between Pump and compressor is the pump transfers liquid from one place to another place whereas the compressor is used for storage of squeezed gas and then it supplied at the required place.

Before moving to further detailed explanation lets have some overview of Pump and compressor.

Note: At the bottom of every article the PDF link is attached make sure if you want you can easily download.


It is a device that is used for lifting the liquid from one place (ground) to send at another place (Top surface).

There are mainly two types of Pump:

  1. Dynamic Pump and
  2. Positive displacement pump


A compressor is also known as a mechanical device.

The compressor increases the pressure energy of a gas by reducing its volume. In simple it is a storage type device.

Difference Between Pump and Compressor:

A Pump is a device that transfers fluid from one place to another required place. Whereas,A compressor is also a device that is used for the storage of squeezed gas and supply whenever needed.
The pump is used to transport fluids like water, oil and so on.The compressor is used to transport only gases.
The pump does not have any storage capacity to store upcoming fluids.But the compressor has storage capacity and then it delivers through pipe wherever required.
The pump is mostly used to increase the energy of an incompressible fluid.The compressor is mostly used to increase the energy of the compressible fluid.
The pressure of the fluid may or may not change in the Pump.The pressure of the fluid must change in the compressor.
While transferring or sending or moving the fluid the volume remains constant from inlet or outlet.In compressor the inlet and outlet is different that means the volume does not remain constant.
The pressure energy increase when the water is sending to any height.But here the energy increases while compressing the fluid.
The pump price is cheaper.A compressor price is more expensive.
In domestic places the pumps are used at several places like in the washing machine, lifting water from the ground to tank, it is also used in several systems like Aeroplane, ship and so on.The compressor is also used in a domestic place like filling the air into cycle or motorcycle, car and so on.

So this our short presentation on the difference between Pump and Compressor, I hope you like it if so, let me know your thoughts in the comment section.
