Hale MBP Booster - Manual (Page 26)

25 Silencer Series Booster Pump, p/n: 029-0020-83-0
Introduction
❑
After the temperature returns to a safe level, the valve closes.
TRV-L Kit
(See Figure 2-11: “Thermal Relief Valve, TRV,” on page 24.)
The TRV-L kit includes a chrome panel placard with a warning lamp, a lamp
test button, and a pre-assembled wire harness. The light illuminates when
the TRV is open and discharging water.
An optional buzzer provides audible warning. The buzzer mounts on the
operator panel.
Anodes
(See Figure 2-12: “Hale Anode.”)
The Hale Anode System helps prevent damage caused by galvanic corro-
sion in the pump. Galvanic action pits the pump and pump shaft material
through the electrolysis of water in the pump. The popularity of noncorro-
sive water tanks and piping has increased this type of corrosion in today’s
fire pumps.
The Hale Anode System is a sac-
rificial metal, which helps to
diminish or prevent corrosion.
The anode fits on any Hale truck
mounted pump, regardless of
age or model.
The Anode kit is designed for
installation in the standard Hale
115 series flange opening. On
fabricated manifolds and similar
applications, the installer is to
provide 1-1/4” NPT openings and
install anodes directly. It is rec-
ommended that one anode be
installed on each suction manifold and one on the discharge side. Typically,
three are used. Anodes can be mounted in any position, horizontal or
vertical.
Zinc anodes should be inspected every twelve (12) months. Replace when
over 75% of the zinc has been consumed. Performance of the anode varies
with water quality and PH. Anodes conform to Mil Spec. A18001.
