The selection of slurry pumps mainly has the following principles:
1. Medium characteristics
Fully consider the concentration, particle size, corrosiveness, etc. of the conveying medium. For example, for high-concentration, large-particle media, it is necessary to select a pump with good wear resistance.
2. Flow and head requirements
Make sure that the selected pump can meet the flow and head requirements required by the process, and have a certain margin.
3. Working environment
Including temperature, pressure, installation conditions, etc. For example, a high-temperature resistant slurry pump needs to be selected in a high-temperature environment.
4. Reliability and durability
Please give priority to pump types and brands with reliable quality and long service life.
5. Efficiency
Select a pump with higher efficiency to reduce energy consumption.
6. Installation and maintenance convenience
Consider whether the installation, disassembly and daily maintenance of the pump are convenient and quick.
7. Cost factors
Comprehensively consider the equipment procurement cost, operating cost and maintenance cost.
8. Adaptability
It should be compatible with the entire process and other equipment to ensure the coordination of the system.

For example, in a coal chemical project, a slurry pump with high wear and corrosion resistance was selected based on the corrosiveness and particle content of the medium; in another project, a compact slurry pump model was selected considering the limited installation space.
