Selection of micro-flow pulse-free pumps
Thread Content
I have an ammonia solution with a flow rate of 40 L/h, and the process requirements specify that there should be no pulsations in the flow. Metering pumps can be used to achieve low flow rates; previously I used imported gear pumps, which were capable of delivering very low flow rates. For this current project, I prefer to use domestic pumps. I’m not sure which suppliers are available; thank you.
It is recommended to use a magnetically driven micro gear pump, with a price ranging around 3,000–4,000 yuan.
