Why gas can not be transfered by pump?

Gas cannot be transferred by standard pumps because it is compressible and behaves differently than liquids. While liquids can flow easily through pumps due to their incompressibility, gases can change volume and pressure significantly, which complicates the pumping process. Additionally, specialized equipment, such as gas compressors or blowers, is required to move gas effectively, as they can handle the fluctuations in pressure and ensure safe transfer.
