    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.
