EC-1-DV 

‘Suction Lift’ Condensate Pump

 

The EC-1-DV model is designed to accommodate multiple electrical requirements within one pump. 
The DV suffix indicates that the pump is capable of operating from a wider range of supply voltages 
to maintain consistent performance. Similar to our EC-1 model, this model incudes improved noise 
reduction, reliable solid-state switching technology, and easy to install mounting brackets to create a 
pump that benefits contractors, installers, and end-users. 
 

 

Normally-closed relay rated at 8 A resistive - 250 V
