2A.1 ANODES
The Hale Anode System helps prevent damage caused by galvanic corro-
sion in the pump. Galvanic corrosion occurs when different conducting
materials are connected electrically and exposed to fluid. This results in
corrosion of the less resistant of the two metals, while the more resistant
metal is protected. (See Figure 2a-1: “Hale 1-1/4” NPT Anode.”)
Hale offers two types of
anodes:
❑
Zinc anode - recommended
for pumps where corrosion
is an issue, including
brackish or salt water expo-
sure.
❑ Magnesium anode - avail-
able for use if the pump
already uses zinc anodes
and galvanic corrosion is
still a concern. Magnesium
anodes contain a notch in
the hex head for identifica-
tion.
The Anode kit is designed for installation in the standard Hale 115 series
flange opening. It is recommended that one anode be installed on each suc-
