Hemitric pump
Thread Content
I have a Sea-Me-Sub shielded pump at home. What does the rated flow rate of 2m3+1m3 mean? Does anyone understand this?
The flow rate is too low; 1 cubic meter of return flow has been added. If it falls below the minimum flow rate for thermal control, the medium will heat up and eventually experience cavitation. If the flow rate is too low, the vibration of the pump will increase.
Oh, it means that when this pump is operating normally, some backflow should be allowed, and then the main flow rate is controlled using a valve
Yes, you must ensure the total flow rate at the pump outlet; otherwise, the pump is prone to damage
