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.
