Pump Industry Experts, Your Consultant

Helping You Find the Right Pump – With Confidence and Expertise   Nanjing Suou Pump & Valve Co., Ltd. For over 20 years, Nanjing Suou Pump & Valve Co., Ltd. has specialized in helping international buyers source the right pumps from China—saving costs while improving technical precision. Why China? Why Now? China's economic rise over the past 40+ years has led to the development of the world's most complete industrial supply chain, particularly in steel, electricity, and heavy machinery. As a result, Chinese-made pumps have evolved from low-end alternatives to globally competitive products—delivering both performance and affordability. From construction and municipal engineering to oil & gas, chemical, and power generation sectors, pumps made in China are now integral to fluid control systems worldwide. However, the vastness and complexity of the market create a major challenge: With 6,000+ pump manufacturers in China, how do you find the one that’s truly right for your project?     What Makes Us Different? We don’t just sell pumps—we deliver solutions. Application-Centric Technical Expertise   Pumps are not “one size fits all.” Selecting the wrong pump can lead to inefficiency, mechanical failure, or excessive costs. We draw on our years of experience in industrial project support to guide customers in selecting the right pump type—centrifugal, submersible, self-priming, high-head, wear-resistant, chemical transfer, and more—based on actual operating conditions.   We've worked with use cases involving:High-temperature or low-temperature fluidsAbrasive slurries and corrosive chemicalsStrict energy efficiency requirementsRemote or challenging environmental conditions           Through continuous content sharing on Douyin, TikTok, YouTube, and Tencent Video, we help educate customers and partners with real-world examples.       Comprehensive Supply Chain Integration   We maintain strategic partnerships with renowned global brands like:KSB,Grundfos,Xylem,Tsurumi,DAB,Desmi   ...as well as a vast network of trusted Chinese manufacturers, each with its own strengths in different pump categories.   To meet diverse customer needs, we’ve also launched our own “SO” brand, offering tailor-made pump solutions based  on international standards and customer-specific requirements.       We personally visit, audit, and assess factories to ensure the quality, capacity, and reliability of every supplier we recommend—something very few trading companies do.                                                                                                                         What We Deliver 💡Product Selection Support Technical advice based on application, medium, and performance requirements. 🧩Supplier Matching & Qualification We shortlist top-tier manufacturers based on your budget, volume, and lead time needs. 📦Logistics & Packaging Solutions Export-friendly packaging, shipping coordination, and delivery planning. 🔧OEM/ODM Services Custom pump design under your brand, label, or technical specifications. 📹 Factory Transparency Factory inspection videos shared openly on social platforms to build trust. Our Vision: To Be Your Long-Term Sourcing Partner We understand that in major infrastructure or industrial projects, every detail matters. Although pumps may account for a small portion of a project's total cost, choosing the right supplier can have a huge impact on performance, reliability, and your bottom line. By offering industry insight + supply chain strength, we help international clients enhance their procurement confidence, competitiveness in bidding, and profit margins after project execution.
