This utility model discloses a dual-condition cooling and heating integrated device for a feed pump, relating to the field of dual-condition feed pump technology. It includes a base, an electrical box, a material box, a storage box, a dual-condition feed pump, a cooling assembly, a cooling mechanism, a heating mechanism, and a material extraction mechanism. The bottom of the dual-condition feed pump is fixedly connected to the top of the base near the rear side of the electrical box. A material extraction pipe is fixedly connected to the output end of the dual-condition feed pump, and a feed pipe is fixedly connected to the input end of the dual-condition feed pump. A diversion pipe is fixedly connected to the outer wall of the feed pipe near the left side of the cooling assembly, and a one-way valve is provided on the outer wall of the feed pipe near the right side of the diversion pipe. This utility model, by operating the dual-condition feed pump, can cool the conveyed material when the temperature is high through the cooling assembly and cooling mechanism, and heat the material when the temperature is low by conveying it through the diversion pipe via the extraction pipe and then heating it through the heating mechanism.
