The optimum for gaseous liquid feeding
Electromagnetic metering pumps EWN-A series
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.
Entrained air is automatically expelled from the pump head. No special degassing is needed.
The pump immediately resumes operation without gas lock even after a long period of stoppage.
Use the air vent port manually for quick release of discharge line pressure.
