Create a New Variable Speed Pump Control Curve

The contractor wanted to reduce the speed to get to 1115 GPM. The blog, “Hydronic Pump Balance using the Variable Speed Drive (VFD) with No Balance Valve on Pump,” indicated a proportional speed reduction would be close. A new system curve would have to be plotted to get the exact speed required using the specified control head.

Variable Speed Pool Pumps Building America

A variable-speed pool pump can reduce pool pump energy use by 50% to 90%. The majority of the savings is derived from a variable-speed pump’s ability to reduce the rpm of the motor, thus reducing energy use. A typical 1½-horsepower (hp) pool pump draws about 2,000 watts and runs at 3,450 revolutions per minute (rpm).
