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 exposure.
❑ Magnesium anode - available
for use if the pump already
uses zinc anodes and gal-
vanic corrosion is still a con-
cern. Magnesium anodes
contain a notch in the hex
head for identification.
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-
tion manifold and one on the discharge side. Performance varies with water
quality and PH.
