The invention discloses box type non-negative pressure water supply equipment, and belongs to the technical field of water supply equipment. The box type non-negative pressure water supply equipment comprises a water supply box, a water supply pump and a bottom plate, the water supply box, a water pump seat and a control box are fixedly mounted at the top of the bottom plate, the water supply pump is fixedly mounted at the top of the water pump seat, a top groove is formed in the top surface of the bottom plate, a water pumping assembly is arranged on the outer wall of one side of the water supply pump, a buffer vibration guide mechanism is arranged outside the water supply pump through a buffer ring, and a water diversion pipe is fixedly mounted on the other side wall of the water supply pump. According to the box type non-negative pressure water supply equipment, the buffering vibration guide mechanism is arranged outside the water supply pump, and on the one hand, the buffering vibration guide mechanism can effectively relieve vibration generated during work of the water supply pump; and on the other hand, unavoidable vibration is utilized and compensated reversely, the effect of dredging in a pipe without an additional driving source is achieved, the situation that the interior of the pipe is blocked due to impurity gathering and caking caused by alternate cooling and heating is effectively avoided, and the working effect of equipment is greatly improved.
