The EWN-A comes equipped with an automatic air vent valve as standard for reliable gas venting. The air vent valve enables easy pressure release via discharge hose. Gaseous liquids such as sodium hypochlorite and hydrogen peroxide can be injected without gas locking
The optimum for gaseous liquid feeding
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. Capable of pumping concentrated sodium hypochlorite.
High resolution
The stroke rate can be set with 1spm increments between 1 and 360 spm. The stroke length adjustment further assists fine adjustment that the stroke rate adjustment cannot achieve. Continuous precise chemical feeding comes as standard.
Multi voltage
The use of the multi voltage circuit design allows the pump to work anywhere in the world.
