China South-to-North Water Diversion Project | Large-Scale Water Transfer Pump Solutions – Kaiquan

At Huai’an No. 2 Pumping Station in Jiangsu Province, Kaiquan developed a 4.5-meter vertical fully adjustable axial flow pump, recognized as Asia’s largest single-unit axial flow pump. The unit delivers an impressive flow rate of 60 m³/s, with a head of 4.89 m, an efficiency of 89.6%, and a 5,000 kW motor. During installation, Kaiquan applied 3D modeling and on-site measurements to optimize equipment alignment and ensure installation accuracy.

For the Western Anyang Water Diversion Project in Henan Province, Kaiquan supplied 14 horizontal split-case double-suction pumps, ranging from 710 kW to 1,000 kW, for a three-stage pumping system with a total lift of approximately 275 meters. The solution was developed through on-site surveys, hydraulic modeling, and repeated technical verification to meet demanding requirements for efficiency and reliability.

Key Technical & Operational Features

Large-Flow Pumping Capability: The Huai’an project demonstrates Kaiquan’s engineering and manufacturing capabilities for ultra-large axial flow pumps in high-volume, low-head water transfer applications.

High-Lift & Energy-Efficient Operation: The Anyang project combines multi-stage high-lift conveyance with high-efficiency double-suction pumps, supporting reliable long-distance water delivery.

Customized Engineering Support: From 3D installation modeling to hydraulic analysis and field verification, Kaiquan provided project-specific technical solutions for complex water infrastructure.

Impact & Industry Recognition

Through the Huai’an and Anyang projects, Shanghai Kaiquan demonstrated its ability to address diverse water-transfer requirements—from high-volume axial pumping to high-lift pressurized conveyance. These projects further strengthened Kaiquan’s experience in supplying reliable, energy-efficient pumping solutions for large-scale water infrastructure.
