The invention discloses integrated high-pressure pumping equipment. The integrated high-pressure pumping equipment comprises an engine, a high-pressure pump, a speed reducer and a frame, the frame comprises an upper frame body and a lower frame body, the engine is arranged in one of the upper frame body and the lower frame body, the high-pressure pump is arranged in the other one of the upper frame body and the lower frame body, the speed reducer is vertically arranged close to the frame, an input end of the speed reducer is connected with the engine, and an output end of the speed reducer is connected with the high-pressure pump. The engine and the high-pressure pump are vertically arranged in the integrated equipment, and the speed reducer is vertically arranged close to the frame, so that the size of the high-pressure pumping equipment is diminished greatly, the structure of entire equipment is compact, and transportation of the high-pressure pumping equipment in severe conditions such as in remote mountainous areas is facilitated.
