Single Phase Simplex Timed Dose Pump Control

model td panel with new timer

The Model TD Build-A-Panel™ control panel provides greater flexibility by ordering through options, allowing you to customize a standard panel to your specific needs.

The Model TD control panel provides a reliable means of controlling one 120/208/240V single phase pumps in on-site septic installations requiring timed dosing.

A programmable timer activates a magnetic motor contactor to turn the pump on and off. A low level cutout float overrides the timer to prevent the pump from running dry. An alarm float activates the audio/visual alarm system indicating a high liquid level.

Common applications include sand filter systems, pressure distribution systems, mound systems or any application requiring a timed dose.
