About Us
San Jiao Zhou Enterprise was established in Shunde, Guangdong in 1992. In 2001, the company began a strategic product transformation through collaboration with E-CHEN which is pioneer in diaphragm booster pump manufacturing in Taiwan.
For more than 30 years, San Jiao Zhou has focused on innovation in energy-saving and health-oriented products, gradually becoming a well-recognized manufacturer in the domestic and international water purification industry. The company owns several well-known brands, including “San Jiao Zhou,” “E-CHEN,” and “Tianlin.”
In 2019, it was recognized as a National Intellectual Property Demonstration Enterprise and currently holds more than 150 valid patents worldwide. Guided by China’s goals of achieving Carbon Emission Peak by 2030 and Carbon Neutrality by 2060, as well as the national strategy for the health industry, San Jiao Zhou continues to innovate its products to meet the market’s high standards.
The core products are diaphragm booster pumps, covering four main series: household large-flow, household low-flow, commercial, and RV applications. The company continues to advance toward automated and digitalized manufacturing.
In addition, we continue to invest in the strategic high-end product “MUYUBAO” to support expansion to international markets.
San Jiao Zhou operates a production base of approximately 10,000 m2 and maintains long-term technical alliances with the Institute of Engineering Thermophysics, Chinese Academy of Sciences (IET, CAS), as well as other leading enterprises. These collaborations support a strong R&D team and a broad international perspective.
Over the years, San Jiao Zhou has established long-term and stable strategic partnerships with well-known domestic and international brands such as Haier, Chang Hong, and Canature, jointly promoting the healthy development of China’s water purification industry.
