CF-12 Chemical Feed Pump Controller

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.

The CF-12 is available with 1 or 2 sets of receptacles. (1 Gang or 2 Gang)  The 1 gang model has 1 switched receptacle and 1 always-on receptacle and the 2 gang has 2 receptacles of each.   Model CF-12 is available for 120VAC, 50-60 Hz power, for pipe sizes ¾ inch to 2 inch.
