WebSep 9, 2024 · The maximum allowable speed is also typically shown on the pump curves chart, since most pumps can’t run at what the top motor speed is. Flow. The flow (#3 on pump curve chart, measured in GPM/Liters Per Minute) is determined by pump speed (RPM). Once the pump speed information is known you can determine the flow on the … Webpump curve minimizes changes in flow through a given zone circuit as other zone valves open and close (see TD01, When Zone Valves Close,for additional information). READING FLOW WITHOUT FLOW METERS The fact that a circulator always operates along its pump curve makes it possible to find the circuit’s flow rate without using a flow meter.
