Chemical Feed and Pump Controllers
CF-8 Chemical Feed Pump Controller
CF-8 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-8 Chemical Feed Pump Controllers are also used to control irrigation chemical feeders and UV lights or Ozone generators on swimming pools
The CF-8 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-8 is available for 120VAC, 50-60 Hz power for pipe sizes from 1 inch to 6 inch.

Specs
HYSTERESIS (Δ FLOW RATE TO ACTIVATE/DEACTIVATE SWITCH)
≈ 10% at upper end of flow range
≈ 30% at lower end of flow range
DIFFERENTIAL PRESSURE DROPS ACROSS UNIT
Under normal operating conditions:
≈ 1″–3″ pipe, less than 0.5 psi
≈ 4″–10″ pipe, negligible
WORKING LINE PRESSURE:
50 psi max., operating @ 180˚F 100 psi max. non-operating @ 180˚F Pressure over 50 psi can affect the switch point range
