They have low maintenance costs, a compact design, small size, and light weight； The exhaust is continuous and uniform, with no need for devices such as intermediate tanks between stages ； Low vibration, few vulnerable components, and no need for a large and bulky foundation ； Apart from the bearings, there is no need for lubrication inside the machinery, which saves fuel and prevents contamination of the compressed gas ； High rotational speed ； Easy to adjust.
Centrifugal pumps are mainly used in applications with high gas flow rates and low head pressure; they are expensive per unit. Reciprocating pumps, on the other hand, are used in applications with high head pressure and low flow rates; they have higher maintenance costs and a higher failure rate, but are cheaper per unit.

Compressors are generally characterized by their compression ratio to indicate the amount of work they perform; head is rarely used for this purpose. Pumps, on the other hand, are expressed in terms of head

First, the forms are different: centrifugal compressors belong to the velocity type, while reciprocating compressors belong to the positive displacement type. Secondly, it is the difference in operating methods: centrifugal compressors require proper anti-surge measures during operation, while reciprocating compressors need strict control of outlet overpressure. Thirdly, the operating conditions differ; centrifugal compressors are suitable for high flow rates and low pressures ； Reciprocating compressors are suitable for low flow rates and high pressures.
