The advantages of liquid pumps and gas pumps are mainly differentiated by the characteristics of the media they transport, with the following key points:
Advantages of Liquid Pumps
Stable high-pressure output
Liquids are incompressible, so liquid pumps can deliver steady and high pressure for long-distance transportation or high-resistance scenarios, such as high-rise water supply and oil pipeline transportation.
Precise flow metering
Flow rate can be accurately controlled by adjusting parameters like rotation speed and stroke, which is ideal for quantitative batching in chemical and pharmaceutical industries.
Auxiliary cooling/lubrication
Some liquid pumps can cool or lubricate associated equipment while transporting liquids, for example, the water pump in an automobile engine.
Advantages of Gas Pumps (including vacuum pumps)
Rapid pressurization or vacuum creation
They can quickly compress gas for inflation (e.g., tire inflators) or extract gas to form a vacuum environment, applicable to vacuum packaging and laboratory vacuum drying ovens.
Strong medium adaptability
With pump bodies made of special materials, they can transport various gases including inert and corrosive ones, meeting the needs of chemical and electronic industries.
No liquid residue contamination
The gas transportation process leaves no liquid residues, making them suitable for cleanliness-critical scenarios such as semiconductor manufacturing and medical negative pressure suction.
