in order to minimize the risk of crevice corrosion .
The chart below illustrates the corrosive
resistance 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 .
