Chongqing Wanlong Pump Valve Co., Ltd. (Anhui Wanlong Pump Valve Co., Ltd. Chongqing Branch) was established in 1985. It was one of the earliest companies in China to introduce the patented material "fluoroplastic alloy" from the Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences, for manufacturing corrosion-resistant materials. The company specializes in producing fluoroplastic alloy magnetic pumps (models CQB, IMD, ZMD), centrifugal pumps (models IHF, IHF(D), FSB, FSB(D)), self-priming pumps (model FZB), slurry pumps (model UHB-ZK), submerged pumps (model FYH), fluoroplastic pipeline pumps (model GF), stainless steel magnetic pumps (models CQ, CQL), stainless steel centrifugal pumps (model IH), stainless steel pipeline pumps (model IHG), as well as fluoroplastic-lined ball valves, globe valves, discharge valves, fluoroplastic-lined angle globe valves, fluoroplastic-lined sight glasses, PTFE-lined and PO-lined pipelines and pipe fittings, among over 200 product specifications. These products are widely used in petrochemicals, acid and alkali production, non-ferrous metal smelting, pickling and painting processes in automobile manufacturing, rare earth separation, pesticides, dyes, pharmaceuticals, papermaking, electroplating, and the radio industry. They are suitable for conveying highly corrosive, flammable, explosive, toxic, volatile, and other chemical media. The products are sold in 28 provinces, municipalities, and autonomous regions, serving over 3,000 customers in processes such as chlor-alkali water, wastewater treatment, and acid addition in ion-exchange membrane caustic soda projects. The products are also exported to Eastern Europe and South Asia, earning widespread acclaim from domestic and international customers. The company has established long-term and friendly technical collaborations with more than ten domestic universities and scientific research institutions, receiving support in functional materials science, fluid mechanics, mechanical design and manufacturing, mold development, machining processes, and heat treatment, thereby enhancing the company's development potential. To ensure product quality, the company successfully passed the ISO9001 international quality system certification in August 2000 and again passed the ISO9001:2000 version international quality system certification in May 2003.

The company has been awarded provincial honors such as "Contract-Honoring and Creditworthy Enterprise" and "Quality Trustworthy Enterprise." It is recognized as a "121" technology demonstration unit and has been conferred titles such as "Star Enterprise," "Advanced Enterprise in Technology Development," and "Quality Trustworthy Enterprise" by the provincial government. Its flagship product, the magnetic pump, has received awards including the "Outstanding Achievement Award in Technology Development" from the National Economic Commission, the "Second Prize for Provincial Scientific and Technological Progress," "Anhui High-Tech Product," and the "Third Prize for Scientific and Technological Progress" from the Chinese Academy of Sciences.
