China has become the global hub for pump manufacturing, ranging from massive industrial systems to the tiny precision pumps found in your kitchen appliances. If you are sourcing from China, here are the top 10 companies leading the industry today, categorized by their specialty.

LEO is a major public company and a powerhouse in the export market. They cover almost everything: agriculture irrigation, domestic water supply, and industrial processes. They are a reliable go-to for standard commercial pumps sold worldwide.

3. CNP (Nanfang Pump)

CNP was the first company in China to mass-produce stainless steel centrifugal pumps. They are the market leaders in water treatment, ultrafiltration systems, and industrial cleaning where durability and corrosion resistance are required.

Lingxiao has carved out a niche in the leisure industry. They are a top producer of plastic pumps for whirlpool bathtubs, spas, and swimming pool circulation systems.

10. Wilo (China)
