Abstract
A fire-fighting pumper vehicle that includes a cab configured to transport a crew of firefighters, a water tank disposed to the rear of the cab, and a chassis configured to support the cab, the water tank, and one or more fire pump systems disposed on the chassis proximate to, and forward of, the rear wheels. In some embodiments, the fire pump system includes a power take-off pump, which is configured to operate a water only system or a compressed-air foam system from a gear case of the fire pump. The fire pump system includes nested components and is located and configured to occupy less space than conventional fire pump systems.
