RobustThe mechanical structure of the hydraulic parts in contact with the pumped liquidare dimensioned to guarantee the maximum resistence to mechanical stress.

Self primingThe hydraulic design allows the pump to self prime even with the high suctionlifts or with long suction pipe runs above the water level.

FlexibleThe option to choose between cast iron and bronze materias for the hydraulicparts in contact with the pumped liquid allows NG series pumps to be selectedfor use with different types of liquids.
