Engineered for high efficiency, continuous operations, and severe-duty environments, meeting the rigorous standards of Tokyo's engineering demands.
The Tokyo Metropolitan Area, comprising the Keihin Industrial Zone, represents one of the world's most sophisticated and concentrated industrial corridors. With a heavy focus on advanced electronics, biotechnology, food processing, chemical production, and municipal water reclamation, Tokyo's industrial plants operate under space constraints, strict ecological regulations, and demand zero-downtime reliability. In these high-intensity operating setups, pump systems form the core kinetic drivers of fluids, chemicals, and gases. Consequently, procuring high-quality pump spare parts that match Japanese Industrial Standards (JIS) is not just a maintenance task, but a strategic operational requirement.
Our commitment to serving the Tokyo market centers around supplying fluid handling spare parts that exhibit extreme durability under continuous load cycles. From municipal wastewater treatment works in Koto and Ota wards to chemical refineries in Kawasaki and Chiba, we understand that a minor component failure can trigger expensive operational halts. By integrating modern materials and advanced machining technologies, we bridge the gap between global supply chain efficiency and Tokyo's precision expectations.
The convergence of digital automation, environmental compliance, and life-cycle cost optimization drives our engineering decisions.
Modern Tokyo industries are rapidly shifting toward smart predictive maintenance. By embedding vibration and thermal sensors into pump assemblies, industrial plants predict spare part replacement cycles, preventing catastrophic failure and minimizing excess stock holding costs.
With tightening environmental protection laws in Tokyo, industries are phasing out oil-lubricated blowers and pumps. The demand for oil-free air foil bearing blowers and magnetic suspension systems has spiked across municipal aeration and clean manufacturing networks.
Abrasive chemical slurries quickly deteriorate standard stainless steel impellers. The industry is adopting specialized sintered ceramics and composite alloys that extend the life span of critical pump internals by up to 300% under high-corrosion environments.
Shandong Zhangqiu Blower Co., Ltd. (formerly known as Shandong Zhangqiu Blower Works) is a prestigious listed company with over 50 years of experience in blower design, engineering, and manufacturing technology. Certified on the Shenzhen Stock Exchange (Stock Code: 002598) since July 7, 2011, we stand as a leading enterprise in the industry, dominating the national market occupancy for Roots Blowers.
Our global outlook drove us to establish two Sino-Japanese Joint-ventures and a dedicated United States branch, cementing our status as the first Chinese blower enterprise to set up overseas operations. Adapting to the modern demands of global technology hubs, we operate state-of-the-art manufacturing plants and technical support systems in China and abroad, serving clients in over 50 countries with a solid market footprint.
Our overall corporate strategy is defined by: "Develop main business, pioneer new fields and innovate, cooperate to be a great company", paired with our primary working philosophy: "Do the best". This guarantees that Tokyo businesses receive engineering designs that adhere to strict precision, minimizing operational losses through proven technology.
In 2005, the company transitioned to a newly built, high-standard, modernized industrial park covering an expansive 430,000 square meters. Equipped with complete facility infrastructure and a magnificent headquarters building, this park provides the physical foundation for scalable cooperation with domestic and international enterprises. By executing a decentralized manufacturing strategy, we operate four major domestic bases located in Wuxi (Jiangsu), Dongguan (Guangdong), Chenzhou (Hunan), and Jinchang (Gansu). This enables rapid regional material handling and localized shipping configurations.
To support high-end engineering demands, we have established four dedicated research and development centers in Beijing, Shanghai, Shijiazhuang, and Wuxi. This distributed research capability allows us to tap into regional expertise, driving improvements in design, manufacturing, and support cycles for all industrial fluid technologies, including Roots blowers, centrifugal machinery, and industrial slurry pumps.
Combining globally advanced machining centers, PLM systems, and rigorous design verification to deliver unmatched precision.
Our research and development integration is among the most advanced in the global machinery industry. We utilize the Product Life Cycle Management (PLM) system, Computer-Aided Manufacturing (CAM) technologies, Computer-Aided Process Design (CAPP), and Computer-Aided Testing (CAT). These integrated database systems accelerate research iterations, enabling us to transition custom replacement parts from conceptual design to precision production rapidly.
Our machinery centers consist of nearly 100 sets of imported high-precision manufacturing equipment. This includes CNC machining centers, five-axis machining centers, three-coordinate measuring instruments, and digital ultrasonic flaw detection machinery imported directly from Japan and Germany. By utilizing this infrastructure, we ensure that every spare part—from a Roots blower impeller to a slurry pump ceramic sleeve—is finished to tolerance parameters matching the original OEM specifications.
Continuous innovation is validated by our technological proprietary developments. We hold 69 authorized patents, which include 5 invention patents and 2 software copyrights. Our research focuses on key fluid dynamics challenges: countercurrent cooling, blower acoustic reduction, wear prevention, multi-stage tandem configurations, system automation, dynamic mechanical sealing, specialized grease lubrication, and complex twisted-leaf rotor designs.
Our role as the primary drafting unit of national standards for Roots Blowers underscores our status in the industry. As the Vice President Unit of the Fan Branch of China General Machinery Industry Association, we help steer industry regulations, ensuring our products represent the state of the art in mechanical reliability.

Our technological competitiveness relies on our engineering workforce. We employ a dedicated R&D team consisting of state-level experts receiving special allowances from the State Council, senior engineering researchers, and doctoral researchers introduced through regional talent projects. Operating a dedicated "Postgraduate Workstation," we provide a continuous platform for advanced academic research and industrial application development.
Furthermore, we maintain active R&D partnerships with leading institutions, including Tsinghua University, Xi'an Jiaotong University, China University of Mining and Technology, and Shandong University. This collaboration ensures our engineering models incorporate modern fluid dynamics theories, thermodynamics breakthroughs, and metallurgical science, providing a technical backstop for the custom solutions we supply to Tokyo.
We prioritize speed and responsiveness when serving engineering firms in Tokyo. Our design team is configured to deliver detailed 3D CAD drawing files within 24 hours of receiving customer specifications or hand-drawn schematics. This ensures seamless integration with existing piping layouts before production begins.
By respecting individual talent and encouraging engineering autonomy, we drive a standard of quality summarized in our motto: "Do it, and do the best." This cultural focus helps us maintain quality standards and limit mechanical deviations, ensuring consistent performance for the parts we deliver.
