7. Temperature and
corrosion 7.1 Operation
The chart below illustrates the corrosive
resistance of di
ff erent types of stainless steel
related to NaCl concentration and temperature.
All critical parts of the APP water pump is made
of Super Duplex.
If the water pump is operated at high salinity,
always
fl ush the water pump with fresh water at
operation stop in order to minimize the risk of
crevice corrosion.
