1. How to choose the pressure of the metering pump?
When choosing a metering pump, it is generally necessary to know the rated pressure, rated flow, type (diaphragm or plunger) and flow material. The rated pressure of the metering pump generally refers to the port pressure. It is generally better to select the rated pressure to exceed 10%-20% of the actual use pressure during the selection. It can save resources, reduce costs, and improve the actual use of the metering pump. Measurement accuracy.
2. How to choose the flow rate of the metering pump?
When the metering pump is working, the metering accuracy is generally higher between 10% and 90% of the rated flow. Therefore, when selecting the rated flow, the selected flow should generally be equal to or slightly greater than the flow required by the process.
3. How to choose the type of metering pump?
Metering pumps are mainly divided into plunger type and diaphragm type according to different transmission modes. The performance of plunger metering pumps is relatively stable, the metering accuracy is relatively high, and it can transport some relatively high viscosity media. In addition to the advantages, there are some special advantages: there is no leakage during operation, and it can transport special liquids (such as dangerous goods, corrosive liquids, etc.).
