ABSTRACT:
A pumping system for fire fighting vehicles wherein a pair of power take-off units mounted on the vehicle transmission engages with a drive gear within the transmission to separately drive water pumps. The power take-offs are each provided with a clutch wherein selective independent and simultaneous pump operation is possible, and it is also possible to operate one or both of the pumps while the vehicle is moving wherein a "pump and roll" capacity is achieved. The vehicle includes a water storage tank selectively communicating with an inlet manifold communicating with the pump inlets, and an outlet manifold receives the pumps' discharge. The manifolds are provided with hose fittings at each vehicle lateral side, and the two pump system of the invention is readily installable in medium size vehicles.
