Shanghai Zhonghan Duke Pump Manufacturing Co., Ltd.

Shanghai Zhonghan Duke Pump Manufacturing Co., Ltd. is a high-tech enterprise that researches, develops, and produces energy-efficient pumps and variable frequency water supply systems. It is a world-renowned manufacturer of variable frequency water supply systems, specializing in the research and development of pump-specific variable frequency controllers, variable frequency pumps, and water supply systems, as well as product upgrades. The company has successively developed advanced integrated control variable frequency water supply systems, such as the N747D system and the NQ system, which are widely used in booster water supply fields around the world. Duke is one of the earliest enterprises globally to apply digital integrated full variable frequency control technology to variable frequency water supply equipment, with the NQ series constant pressure variable frequency water supply system being a representative application of this advanced technology. In March 2002, the first PID pump-specific controller was born at Duke. In 2004, we successfully developed the world's first pump-specific variable frequency controller—the Q series digital integrated variable frequency controller, achieving a new milestone in constant pressure variable frequency water supply and obtaining an international patent certificate. Shanghai Zhonghan Duke Pump Manufacturing Co., Ltd. is located in the Liantang Industrial Park, Qingpu District, Shanghai. Shanghai Duke possesses advanced product manufacturing process equipment and hydraulic experimental platforms, mainly undertaking the research, development, production, and product upgrading of pump systems and variable frequency water supply systems. Shanghai Duke has now become one of the outstanding enterprises in China's secondary water supply, building booster water supply, and urban water supply fields. In 2008, it obtained Shanghai's energy-saving product certification, becoming the earliest and only enterprise in China to receive government-level recognition for water supply equipment energy-saving products. In 2012, Shanghai Duke's DRL series variable frequency water supply system was rated as a "Green Building Energy-Saving Recommended Product." In September 2014, Duke, as the lead editing enterprise, compiled China's first professional technical specification for fully variable frequency control water supply equipment—the "Application Technical Regulations for Digital Integrated Full Variable Frequency Control Constant Pressure Water Supply Equipment." In June 2015, the Building Water Supply and Drainage Research Branch of the China Architecture Society established the "National Secondary Water Supply Full Variable Frequency Control Technology Research and Development Center" at Shanghai Zhonghan Duke, with the "Center Laboratory" located in the Shanghai Duke factory, making it the only manufacturing enterprise under the society engaged in the integration of production, education, and research in the secondary water supply field. Additionally, Duke is the highest-level enterprise member of the World Water Council in China. Against the backdrop of economic globalization, Duke, leveraging its core research and development achievements in pump system development and pump-specific integrated variable frequency control technology, has become a global leader in the secondary water supply field, especially in integrated full variable frequency control water supply. Our integrated full variable frequency control water supply equipment has been successfully applied to building and urban secondary water supply in 26 developed countries, including the United States, the United Kingdom, Japan, and Denmark. In China, we provide Duke's excellent secondary water supply solutions and system products to over 360 water supply companies. Guided by the business philosophy of "integrity, quality, innovation, and progress," and with product development centered on "safety and reliability, high efficiency and energy saving, and convenience and user-friendliness," Duke adheres to the corporate tenet of "customer first," always aiming for customer satisfaction, serving the Chinese market.
