Explore our elite range of industrial pumps, roots blowers, steam compressors, and high-temperature air handling solutions designed for extreme durability and efficiency.
Shandong Zhangqiu Blower Co., Ltd. (formerly known as Shandong Zhangqiu Blower Works) is a prestigious listed company (Stock Code: 002598 on Shenzhen Stock Exchange since July 7th, 2011) boasting over 50 years of comprehensive design, manufacturing, and application experience. We stand at the forefront of China's blower industry, setting the gold standard for innovation and technology.
ZCBC is the chief drafting unit of Chinese national standards for Roots Blowers, representing the peak of national manufacturing prowess. Strategically expanding globally, we have established two Sino-Japanese Joint-ventures and a dedicated USA branch, becoming the first enterprise in China's blower sector to establish a physical operational presence overseas.
Our expansive production hub in Wuxi, Wuxi R&D center, and manufacturing bases in Dongguan, Chenzhou, and Jinchang empower us to serve globally. Guided by our corporate strategy—"Develop main business, pioneer new fields and innovate, cooperate to be a great company"—and our work philosophy "Do the best", ZCBC continues to deliver custom engineering solutions of unmatched quality.
Analyzing technology pathways, thermal stress dynamics, global procurement specifications, and decarbonization solutions for high-temperature operations.
Operating temperatures exceeding 400°C to 1000°C require precise radial and axial expansion calculations. We utilize special heat-dissipating flinger discs, water-cooled shaft channels, and dynamic seal structures to prevent critical mechanical failures.
Standard carbon steel loses yield strength dramatically under thermal load. ZCBC employs custom cast iron alloys, AISI 310S, Hastelloy C, Inconel 625, and duplex stainless steels to guarantee fatigue resistance and prolonged lifecycle in aggressive flue environments.
Reduced air density at elevated temperatures modifies static pressure profiles. Our state-of-the-art computational fluid dynamics (CFD) models allow custom tailoring of backward-curved or radial-tip impeller geometries to maximize gas volume transport while reducing shaft load.

Industrial procurement departments globally require deep technical reassurance when integrating high-temperature centrifugal blowers and fans. Operating inside smelting plants, cement kilns, and glass production furnaces offers no margin for downtime.
Key requirements include compliance with structural vibration standards (ISO 10816), performance parameters matching the system design curves, and robust motor isolation protocols (Class H insulation). At ZCBC, we provide full-system transient structural analysis and modal testing to guarantee reliability. Our teams provide ready-to-integrate 3D CAD files within 24 hours of receiving parameters, reducing engineering lead times for global partners.
How ZCBC's thermal gas handling machinery powers major global heavy industries and sustainable engineering plants.
Mechanical Vapor Recompression demands compressors that handle highly corrosive chemical steam. ZCBC’s high-efficiency Roots Steam Compressors boost temperature and pressure, recycling waste steam and saving over 60% in energy compared to traditional multi-effect evaporators.
From blast furnace cooling to waste heat recovery systems, our heavy-duty high-temperature fans run continuously at 600°C. With integrated water-cooled bearing pedestals, we prevent bearing lubrication breakdown, guaranteeing 24/7 furnace uptime.
Our ceramic slurry pumps and specialized chemical fans handle corrosive sulfur gases and highly abrasive slurries simultaneously. The combination of structural stability and high wear resistance prevents premature casing failure in extreme FGD environments.
The core of ZCBC's manufacturing quality lies in our robust R&D ecosystem. Our facilities host nearly 100 sets of imported advanced machinery, including 5-axis CNC machining centers, three-coordinate measuring systems, and dynamic balance machinery imported from Japan and Germany.
We leverage international PLM (Product Lifecycle Management) and CAM/CAPP (Computer-Aided Process Planning) technologies to achieve precision tolerances down to the micrometer level. In recognition of this rigorous engineering focus, we have secured a suite of global certifications:
Continuous investment in smart tech pathways to redefine thermal airflow efficiency for the next generation of industrial plants.
By suspending the shaft contactlessly in magnetic fields, we eliminate traditional lubricants that fail at high temperatures. ZCBC is designing integrated high-temp turbo blowers incorporating AMB technologies to operate oil-free at high RPMs.
Continuous vibration, temperature, and pressure tracking feeds real-time data back to central control systems. Smart AI algorithms predict bearing thermal failures up to 72 hours before they occur, allowing scheduled preventative maintenance.
Refining mechanical tolerances to reduce gas slippage inside compressors and fans, saving up to 5% more electrical energy per year, supporting global ESG directives and manufacturing carbon-reduction goals.
At ZCBC, we believe that superior engineering starts with brilliant human capital. Through incentives and an attractive workspace, we have built a top-tier research team featuring experts enjoying State Council special allowances, senior doctorate holders introduced through the Jinan "5150" program, and veteran machinery researchers.
Our dedicated "Postgraduate Workstation" bridges the gap between academic innovation and shop-floor reality. We maintain deep technological partnerships with prestigious domestic universities, ensuring that every fan casing, rotor profile, and thermal dynamic balance model utilizes the latest fluid dynamics sciences.
Expert technical answers to essential engineering, selection, and maintenance queries from global procurement managers.
