What is Time Dosing?

Time Dosing control panels are used to control the amount of water a submersible pump can push to the secondary system over a period of time. The Simplex and Duplex control panels listed above are considered On Demand or Demand Dose systems. This means the pump will run when it needs to based upon the float switch in the tank. Time Dosing or Timed Dose panels use a Repeat Cycle timer in which an ON cycle and an OFF cycle is set for the pump and the timer follows that cycle repeatedly.

The reason for time dosing is to equalize the flow of water to the secondary system. In certain applications large amounts of water can be used in a short period of time. This is very hard on a septic system. With a Time Dosing control panel, you can equalize that flow by spreading it out throughout a longer period of time. The Repeat Cycle Timer will dose the system by running the pump short periods of time throughout the day versus an On Demand system (like the Simplex and Duplex Panels Above) that will pump a large amount of water all at once.

Our Time Dosing Control Panels are available in 120V and 230V. We have them for both Simplex and Duplex applications.
