KSB's SPN Pump Embarks on a Mission to Safeguard the Upper Yangtze River
A grand departure ceremony was recently held at KSB Shanghai Pump Co., Ltd. for the KSB SPN 1200 vertical volute casing wastewater pump. This core piece of equipment is destined for the Phase IV expansion of the Chongqing Jiguanshi Wastewater Treatment Plant (WWTP). The successful delivery not only marks another milestone for KSB in producing critical national infrastructure but also signifies that a major environmental project protecting the Yangtze River is about to be powered by a robust, state-of-the-art "heart," proudly made in China.
The Chongqing Jiguanshi WWTP expansion is a high-profile municipal project, tasked with the dual mission of addressing environmental issues identified by central government inspections and rehabilitating the ecology of the Yangtze River Economic Belt.
Upon completion, the plant's total treatment capacity will reach 1.2 million m³/day, making it the largest in Western China and one of the top five in the nation. This massive increase in purification capacity will significantly enhance wastewater treatment for Chongqing's central urban area, providing a solid foundation for a crucial ecological barrier along the upper Yangtze River.
A 12-Meter-Tall "Mega-Heart"
Participating in such a significant project is both an honor and a profound responsibility. As the "heart" of the entire wastewater lifting system, the pump sets supplied by KSB faced unprecedented challenges.
Massive Scale: The SPN 1200 pump set, from the bottom of its intake elbow to the top of its motor, stands over 12 meters tall—a true steel giant.
Massive Power: To achieve the plant's capacity leap from 800,000 to 1.2 million m³/day, KSB engineered a transformative upgrade to the inlet pump station. The new configuration replaces six of the seven original main units with 12,000 m³/h SPN 1200 pumps and adds other SPN series pumps of varying capacities. This delivers not only a quantum leap in total flow rate but also unparalleled operational flexibility and reliability.
Massive Challenge: The immense size and power demand exacting standards for vibration control, flow dynamics, and energy efficiency. Every stage—from transportation and installation to commissioning—presented a significant test of technical expertise and experience.

In response, KSB's technical team deployed its core competencies:
Advanced Hydraulic Models: Ensuring design excellence from the ground up, rooted in KSB's technical DNA.
CFD Flow Simulation: Conducting digital twin analysis of the entire pump station to predict and optimize water flow patterns.
CAE Vibration Analysis: Monitoring each pump set to guarantee rock-solid stability even at high operational speeds.
Furthermore, KSB supplied over 100 other critical process components for the project, including submersible pumps, mixers, and agitators, ensuring smooth operation with a comprehensive product portfolio.

Precise Delivery, Trusted Performance
The project's mantra—"controlling engineering quality with high standards and coordinating construction progress across all stages"—was a challenge for all suppliers.
As a key equipment provider, KSB Shanghai recognized its significant responsibility. Facing the dual pressures of tight deadlines and demanding technical specifications, the KSB team demonstrated exceptional professionalism and execution. Departments worked in close coordination, meticulously controlling quality at every step from design and production to delivery.
Living up to expectations, KSB successfully delivered the first batch of six vertical volute casing pumps and over 100 submersible pumps and mixers in the first half of the year, strictly adhering to the project schedule.
This precise execution was vital for the smooth advancement of the entire project. On June 30th, the plant achieved its initial water commissioning milestone. All installed KSB products have been operating stably and with excellent performance, laying a solid foundation for this phase's success. This achievement reflects KSB's commitment to its customers, its dedication to social responsibility, and the proven strength of "German Technology, Made in China."
With the successful shipment of this SPN 1200 pump, we will continue our efforts to complete the delivery of the remaining pumps for the project's upgrade.
Every shipment is a promise fulfilled; every journey begins with a mission to protect our natural environment. KSB will continue to contribute to China's environmental protection efforts with its cutting-edge technology, reliable products, and professional services, working alongside all partners to build a greener future.
