Model DTD

Single Phase Duplex Timed Dose Pump Control

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

A programmable timer, in conjunction with an alternating circuit board, alternately activates the magnetic motor contactors to turn the pumps on/off and equalizes pump wear.  A low level cutout float overrides the timer to prevent the pump from running dry.  An alarm switch 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 timed dose control.
