PURPOSE: A direct connected fire engine pump device is provided to firmly maintain a power transmission shaft of an engine and an impeller with a fixing flange, a fixing coupler, and a supporter, thereby obtaining stability for pumping and preventing a power loss. CONSTITUTION: A direct connected fire engine pump device comprises a support frame, a power transmission shaft, a pump, a fixing coupler, a shaft protection unit(20), a supporter, and a shock absorbing member(14). The support frame is installed closely to the scene of a fire to support an engine and a pump. The power transmission shaft comprises a fixing flange and a shaft unit of a stepped structure. The fixing flange is connected to a driving plate of the engine. The pump comprises an impeller being installed in the inside of a pump housing and a water inlet and a water outlet. The impeller is joined to the leading end part of the power transmission shaft, thereby pumping by using the power of the engine. The fixing coupler is joined to the leading end part of the power transmission shaft being joined to the impeller. The shaft protection unit comprises a housing, a support flange unit, and a shaft supporting unit. The shock absorbing member buffers shocks generated by the shaft protection unit.
