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 ...
