Flow Controller

Add our flow controller to the Spiral Stack 03's discharge port for precision metering of flow rates from 1.1 gallons per day to 2.6 gallons per minute or to prevent backflow. Use with single-speed or VFD motor. This controller closes off flow when the pump is not in use and opens when the pump powers on. Once the flow rate is set, a locknut prevents unwanted adjustments. 1/4" FNPT discharge.
