EWN-A Dosing & Metering Pumps

This type equips automatic air vent mechanism. An air vent valve builtin pump chamber enables reliable air venting. Also equipped manual air vent valve enables easy pressure release in discharge piping. Gaseous liquid such as sodium hypochlorite or hydrogen peroxide can be injected without gas locking.

Key Features  

The optimum for gaseous liquid feeding 

This type equips automatic air vent mechanism. An air vent valve built-in pump chamber enables reliable air venting. Also equipped manual air vent valve enables easy pressure release in discharge piping. Gaseous liquid such as sodium hypochlorite can be injected without gas locking. 

High resolution 

The stroke rate can be set with 1spm increments in between 1 and 360spm. The stroke length adjustment further assists fine adjustment that the stroke rate adjustment cannot reach. Contentious precise chemical feeding is now available. 

Multi voltage 

The use of the multi voltage circuit design allows the pump to work anywhere in the world. 

Pump housing 

The use of an integrated controller reduces the sealing area, thereby achieving water/dust protection according to the IP65 standard. In addition, a plastic cover protects the control panel from adverse environmental conditions.
