corrosion.
The chart below illustrates the corrosive resist-
ance of different types of stainless steel related to
NaCl concentration and temperature.
The APP water pump is made of Duplex and
Super Duplex.
If the water pump is operated above the Duplex
line, always flush water pump with fresh water at
operation stop in order to minimize the risk of
crevice corrosion.
