Our History
In 1988, WENLING SHANSHI ELECTROMECHANICAL FACTORY was founded in Shanshi town, Wenling city, Zhejiang Province, which later came to be known as DAFU. In 1995, DAFU evolved into TAIZHOU DAFU PUMP CO., LTD. Further, on June 13th, 2014, the company was renamed ZHEJIANG DAFU PUMP CO., LTD and acknowledged as a national high-tech enterprise, achieving the distinction of a well-known Chinese trademark. In 2020, DAFU not only established a corporate love fund and Zhejiang Province enterprise technology center but also obtained the provincial high-tech enterprise research and development center. In 2021, the company lauded another achievement with the incorporation of the provincial enterprise research institute. Subsequently, in 2022, DAFU's development needs led to an investment of 2.2 billion yuan in Yushan County, Jiangxi Province, which declared it as a provincial specialization and national-level industrial behemoth. Finally, in 2023, DAFU established a state-of-the-art production base, DAFU INTELLIGENT TECHNOLOGY CO., LTD., a milestone worth noting.
