Toluene transfer low-flow pump
Thread Content
Question: For operating conditions of 200 L/h of toluene, continuous transportation at room temperature, and a head of 20–30 m, which pump would be suitable? Metering pumps exhibit pulse fluctuations, which affect the stability of the feed flow; are canned pumps and magnetic drive pumps suitable for this purpose? Thank you!
A flow rate of 0.2 m3/h is too low; using centrifugal pumps (magnetic pumps and shielded pumps) would result in very low efficiency. It is recommended to use positive displacement pumps, and a buffer tank can be installed at the outlet of the metering pump to address this issue
The original poster can take a look at my topic; it’s basically the same as your question. The issue has been resolved and everything is running stably now
The flow rate is a bit low; a stainless steel magnetic pump might work
I’ve already seen it and learned about it. Could you recommend the manufacturer you chose?
Pump meters are still more suitable; pulsation can be addressed by using additional equipment.
