A fire fighting apparatus includes a chassis that can be in the form of a trailer that supports a pedestal and an articulating boom with a submersible hydraulically driven pump at an end portion of the boom opposite the pedestal. A diesel engine mounted on the chassis powers both a hydraulic pump and a transfer pump. Water picked up by the submersible pump at the end of the boom is received on the chassis and then transferred under pressure to a fire fighting hose. A dual filter arrangement can be used to remove trash that is picked up by the submersible hydraulic pump. A hydraulic motor on the chassis can be used to operate the boom during unfolding and folding and to transfer hydraulic fluid to the submersible pump.
