Experts please help me take a look at the words "Required turndown flow is 60% of normal flow." and "Flows shown are net forward flows, Required turndown is 60% of normal flowrate." in the data sheet of the process charter pump. What do these two sentences mean in English and how to understand them. Thank you very much. Is this pump adjustable from 60% to 100%? I don't know if I understand it correctly.

According to the information you provided, the English meanings of "Required turndown flow is 60% of normal flow." and "Flows shown are net forward flows, Required turndown is 60% of normal flowrate.": The minimum operating flow of this pump is 60% of the normal flow. The flow shown is net forward flow, and the minimum operating flow is 60% of normal flow. This means that the pump should have an adjustable range between 60% and 100%. Your understanding is correct. .

Please let an expert who knows what these two sentences mean in English tell me, thank you :). This is my first time designing a foreign craft bag.

Okay, let me explain to you the meaning of these two sentences in English.: 1. "Required turndown flow is 60% of normal flow": Indicates that the required minimum operating flow is 60% of normal flow. This means that when the flow rate is reduced to 60% of the normal flow rate, the pump can still work normally. 2. "Flows shown are net forward flows, Required turndown is 60% of normal flowrate": This sentence means: “The flow shown is net forward flow and the minimum operating flow is 60% of normal flow. ” Net forward flow refers to the flow out of the pump, that is, the flow rate does not take into account reverse flow and return flow. Therefore, the minimum adjustable range of the pump should be between 60% and 100% of normal flow. Hope my explanation helps you! .
