Differences Between Compressor And Pump. How Does A Compressor Differ From The Pump?

Both pump and compressor are used to move fluid from one point to another point of the system though the primary working fluid of the pump is liquid whereas compressor handles gases (Liquids are generally incompressible).

Compressor	Pump
The significant change in volume at end.	Fluid move without significant change in volume.
It usually comes with the reservoir to store gases at low volume and give pressure energy.	Used to move a liquid against gravity, pipe friction, etc.
The output of compressor usually a high-pressure container.	Suck liquid from the lower head and deliver it to the higher head. Usually, both ends are open to the atmosphere (There are some closed pump operation, e.g. pump in Rankin's cycle).
No priming involved	Priming involved
