Difference Between Pump and Compressor

Either a compressor or a pump is required at the time of movement of the hydraulic fluid through a specific system. Although both pump and compressed are made to achieve the goal of moving the hydraulic fluid, but there operating methods differ.

However, compressors are responsible for the movement of gases, as only gases can be compressed. In the case of both pumps and compressors, the pressure rises high.

Pump vs Compressor

The main difference between a pump and a compressor is that a pump is a type of machine that is responsible for the movement of a fluid from one area to another. Fluid, in this case, can be either liquid or gas.

Pump vs Compressor

Pumps are used for the movement of the fluids from one area to another at any height. Their main purpose is the transportation of liquid like oil, water, etc.

Compressors are used basically to increase the potential energy, density and pressure of the fluid. Here, the pressure of the fluid is increased by the process of compression.

What is Pump?

A device that possesses the potential to move fluids and slurries produced by mechanical action into hydraulic energy. The fluids are generally converted from electrical energy.

Various energy sources, such as engines, wind power, electricity, manual operation, can be used in the operation process of the pumps. Pumps are available in the market in many sizes.

There is another type of pump available, mechanical pumps. The use of mechanical pumps can be used extensively for various purposes such as aquarium filtering, aeration, pumping water (from Wells), pond filtering.

What is Compressor?

A mechanical device that has the potential to elevate the pressure of the fluid, or especially gas, by lowering its volume is a compressor. There are various types of gas compressor, a specific example of which is an air compressor.

However, some can be compressed some can not. Like, liquids can not be compressed. Compressors work stage wise.

Compressors are of three general types. They are centrifugal, positive displacement and axial.

Main Differences Between Pump and Compressor

  1. Pumps are used for the movement of the fluids from one area to another at any height. Whereas compressors are used basically to increase the potential energy, density and pressure of the fluid.
  2. In the case of the pump, the pressure is increased by moving on to a higher height, whereas, in the case of a compressor, the pressure of the fluid is increased by the process of compression.
  3. Volume remains constant from the inlet to the outlet of the pump. However, in the case of a compressor, the volume keeps on changing from the inlet to the outlet.
  4. The pump’s main purpose is the transportation of liquid like oil, water, etc. Whereas a compressor’s main purpose is the transportation of gases.
  5. In a pump, there are fifty perfect chances of change/ unchanged of pressure. But in the compressor, there are hundred per cent chances of a change of pressure.
  6. The energy of the incompressible fluid is mostly increased by the pumps. Whereas the energy of the compressible fluid is mostly increased by the compressors.
  7. Pumps do not have storage capacity. But compressors possess storage capacity.
Difference Between Pump and Compressor

Conclusion

The machines like pumps and Compressors are hydraulic. These machines are used to enhance the energies of fluid.

Pumps are mostly used to supply gases, liquid and water from lower elevation to higher elevation. A compressor is a mechanical device, like a pump.
