Advanced Stroke Controller

The Neptune Advanced Stroke Controller allows the capacity of any Neptune 500 Series, 600 Series, or 6000 Series Hydraulic Metering Pump to be automatically controlled in response to a standard 4-20 mADC process signal. The one-piece controller-positioner mounts directly to the pump. No machining or any special drillings or tapings are needed to retrofit the pump. The Advanced Stroke Controller is commonly used in water/wastewater, power and process industry applications or anywhere pump flow must be automatically proportioned or varied.
