1. Flow rate of metered liquid: The selected metering pump flow rate should be equal to or slightly greater than the flow rate required by the process. The use range of the SEKO metering pump flow rate is preferably 30 to 100% of the rated flow rate of the SEKO metering pump. At this time, the repeating reproduction accuracy of the SEKO metering pump is high. Considering the economical and practical, it is recommended that the actual required flow rate of the SEKO metering pump be 70 to 90% of the rated flow of the SEKO metering pump;
2. Main characteristics of the liquid to be metered: such as chemical corrosivity, viscosity and specific gravity. Determine the pump head (hydraulic end) material: After determining the specific model specifications of the SEKO metering pump, select the material of the over-current part according to the properties of the over-flow medium. This step is very important. If it is not properly selected, it will cause corrosion of the medium. Flow components or media leaks contaminated systems, etc. In serious cases, it may cause a major accident. If you are not sure, please consult with us.
3. Back pressure of the system: The rated pressure of the selected SEKO metering pump is slightly higher than the actual maximum pressure required, generally 10 to 20% higher. Don't choose too high, too much pressure will waste energy, increase equipment investment and operating costs;
4. Appropriate suction height;
5. Other options required, such as analog control, pulse volume control, flow monitoring, and timers.
