What is the difference between diaphragm compressors and metering pumps? Isn’t this not exactly the same thing?
The diaphragm in a diaphragm compressor is a metal sheet that is used to compress gas. A diaphragm metering pump is a positive-displacement pump; its diaphragm is a non-metallic sheet, and it is primarily used for transporting liquids, not gases
Compressors can only transport gases; their diaphragms are made of metal and consist of three layers, whereas metering pumps can only transport liquids
The compressor transports gas and does work on it. The pump does work on the liquid
What is the difference between diaphragm compressors and metering pumps? The difference is huge; it’s like the difference between a ship and a car – aren’t they not exactly the same thing? If you say it’s the same, then it’s the same
A diaphragm compressor is a compressor with a special structure that provides excellent sealing; the gas does not come into contact with any lubricants, which results in extremely high purity of the compressed gas. It is particularly suitable for compressing, transporting, or bottling certain rare gases, as well as for gases that are corrosive, toxic, flammable, or explosive. It is widely used in industries such as food chemistry, petrochemicals, military industry, air separation, manufacturing, energy, and aviation. A metering pump, also known as a dose pump or proportional pump, is a special type of positive displacement pump that can meet the requirements of various stringent process workflows. Its flow rate can be adjusted continuously within a range of 0-100%, and it is used to transport liquids, especially corrosive ones.
