How does rpm affect pump curve
Webpump is connected to — these include the static head and the dynamic head of the system. The static head is created by any vertical columns of liquid attached to the pump and any pressurized systems attached to the pump outlet. The static head exists under static conditions, with the pump switched off, and does 3 not change based on flow. WebBy slowing the speed down to 1365 rpm the pump develops 40 ft and intersects our system curve with a flow rate of 300 gpm. By further slowing down the pump to 905 rpm the pump develops 17.5 ft of head which intersects the system curve at 200 gpm. The way the pump speeds are determined is by adjusting speed on the known pump curve (in this case ...
