2A.2 AUXILIARY COOLING
Gearbox Manifold Coolers
Figure 2a-2: Typical Gearbox Manifold Coolers
For pumps not equipped with standard gearbox cooling, a cooler option is
available. (See Figure 2a-2: “Typical Gearbox Manifold Coolers.”)
The gearbox cooler circulates pump water to transfer heat from the gearbox
oil to the pump discharge, thus maintaining proper operating temperatures.
Heat Exchanger, “K” Series
The Hale Model “K” heat exchangers, meet NFPA 1901 requirements.
These units are used with any size radiator and use water from the pump to
help maintain the proper temperature of the engine coolant during pumping.
(See Figure 2a-3: “Model “K” Heat Exchanger,” on page 39.)
Note: A valve is normally added at the operator’s panel allowing the operator to
control the amount of water supplied to the Model “K” heat exchanger.
2A.3 PRESSURE AND RELIEF VALVE CONTROL
Note: For additional information about the pressure and relief valves in your sys-
tem, see the separate manual provided with the valves. Also see Section 9,
“Drawing Package” on page 133.
