Construction with mechanical shaft seal and diaphragm to ensure minimal exchange of pump media and motor liquid

The pump head and base are in cast iron – all other wetted parts are in stainless steel

Degassing drive strategy in case of air bubbles detected in the dosing head and Auto Deaeration during pump standby avoids stand-still due to air-locking

The pump is close-coupled to a fan-cooled asynchronous motor
