2.6. Optional Pump Components
In addition to the basic parts of Hale booster pumps described above, the following items are
available to enhance pump operation:
•
Anodes
•
TRVs
2.6.1 Anodes
The Hale anode system (Figure 6) helps prevent pump damage caused by galvanic corrosion.
Figure 7. Hale Anode
Galvanic action pits the pump and pump shaft material. The popularity of non-corrosive water
tanks and piping has increased this type of corrosion in today’s fire pumps. The Hale anode sys-
tem is a sacrificial metal, which helps prevent corrosion. A Hale makes an anode that will fit on
any Hale truck mounted pump, regardless of age or model. The RSD uses Hale anodes designed
to be easily installed ONLY requiring four bolts and a gasket. Total time to install is just fifteen
minutes or less, yet it will provide years of protection for the pump. The anode kit is designed for
installation in the standard Hale 115 series flange opening located on the side of the RSD volute
(K port). On fabricated manifolds and similar applications, the installer is to provide 1-1/4-in NPT
openings and install anodes directly. It is recommended that one anode be installed on the suc-
tion side and one on the discharge side.
