1. Make the type and performance of the selected pump complied with the requirements of process parameters such as device flow, raising, pressure, temperature, steam flow flow, and suction process.

2. The requirements of the media characteristics must be met.

For pumps that transport flammable, explosive, toxic or valuable media, the shaft seal is required to be reliable or leak -free pumps, such as magnetic driving pumps, diaphragm pumps, shielding pumps; pumps that transport corrosive media Materials, such as AFB stainless steel corrosion -resistant pump, CQF engineering plastic magnetic driver pump.

For pumps containing solid particles medium, wear -resistant materials are required to be used for streaming components.

3. High -reliability, low noise, and small vibration.

4. Economically, the total cost of equipment costs, operating fees, maintenance costs and management fees is the lowest.

5. The centrifugal pump has the characteristics of high speed, small volume, light weight, high efficiency, large flow, simple structure, no pulse of infusion, stable performance, easy operation and convenient maintenance.
