Harwil - Model CF-112 -Chemical Feed Pump Controller
The CF-112 Chemical Feed Pump Controller is a stand-alone controller that automatically actuates a chemical feed pump when primary bulk fluid (water) begins to flow. An example would be to start a chlorine injection pump when the water flow starts and turns the injection pump off when the flow stops.
This module can be used in stand-alone systems or part of larger complex systems.
Model CF-112 is available for 120VAC or 240VAC, 50-60 Hz power as standard.
The CF-112 Chemical Feed Pump Controller includes two 6 foot cords, one male to plug into the existing power and one female that the chemical feed pump plugs into. The 240VAC version does not include plugs and is hard wired.
