    • Provided is a simple fire truck that easily moves to a narrow fire occurred spot difficult for a car to enter by using a transfer wheel driven by a motor separately from a pump driven by an engine, the simple fire truck including: a depressurization groove that is formed between a chamber where a sealing unit receiving pressure of the pump is provided, and a suction hole, so as to depressurize a pressure of the chamber; a lubricating water supply unit for improving durability through lubrication and cooling by supplying lubricating water to an inlet of the chamber according to a vacuum pressure generated during an initial activation of the pump; and a rotor unit having a first protrusion at an end of a side of a rotor provided inside the chamber, and a second protrusion at a periphery of a shaft hole through which a rotation shaft penetrates. Accordingly, the simple fire truck easily moves to the narrow fire occurred spot difficult for a car to enter by using the transfer wheel driven by the motor separately from the pump driven by the engine, prevents a damage of the sealing unit by depressurizing a pressure transferred to the sealing unit by forming a groove between the chamber and a suction unit formed inside the pump, and improves durability of a positive-displacement pump through lubrication and cooling by using a lubricating water suction unit provided at a pump suction unit during an initial activation.
