PURPOSE: An engine pump with a structure where a shaft of an engine is directly connected to a pump is provided to maintain the air tightness between an engine and a pump and to minimize an operation process by integrating the engine and the pump. CONSTITUTION: An engine pump comprises an engine(100) and a pump(200). The driving shaft of the engine is directly connected to the rotary shaft(210) of the pump. The rotary shaft comprises a first shaft, a second shaft, and a third shaft. The diameter of the shafts successively shrinks toward the pump. An engine fixture piece is assembled on the first shaft. The engine fixture piece clinches the rotary shaft on the engine. A mechanical seal is assembled on the second shaft. A screw nut is assembled in one end of the third shaft.
