Premium inline centrifugal blowers, roots blowers, and submerged slurry pumps certified to international CE & ISO standards.
The demand for high-efficiency inline centrifugal solutions, multi-stage turbomachinery, and heavy slurry pumps has grown exponentially. As global processing plants seek to maximize energy efficiency while reducing their footprint, inline centrifugal configurations have emerged as a vital baseline technology. Unlike horizontal offset units, inline systems utilize concentric alignment to minimize space constraints and piping complexities, making them highly desirable for modular industrial builds.
From environmental remediation and municipal wastewater aeration to complex chemical processing and deep-pit mineral extraction, these systems operate under harsh thermal and mechanical stress. Our comprehensive manufacturing expertise bridges the gap between raw aerodynamic output and energy-conscious operational costs, helping plant managers meet stringent environmental targets.

Our manufacturing complex spans over 430,000 square meters, housing a state-of-the-art production ecosystem. Shandong Zhangqiu Blower Co., Ltd. has established four manufacturing bases strategically placed in Wuxi (Jiangsu), Dongguan (Guangdong), Chenzhou (Hunan), and Jinchang (Gansu) with dedicated R&D facilities in Beijing, Shanghai, Shijiazhuang, and Wuxi.
Our processing floor is equipped with nearly 100 sets of imported premium machining systems. This includes advanced CNC machining centers, five-axis machining centers, three-coordinate coordinate measuring machines, and ultrasonic flaw detection apparatus imported from Japan and Germany. These high-precision assets allow us to manufacture with absolute structural integrity, keeping mechanical clearances tight to maximize overall hydraulic and volumetric efficiency.
Configured solutions designed for deep integration within specific industry verticals.
In municipal and industrial water treatment plants, aeration typically accounts for 50% to 65% of the total electrical operating cost. Our magnetic suspension and single-stage high-speed centrifugal blowers adapt dynamically to variable dissolved oxygen (DO) levels using integrated VFD (Variable Frequency Drive) controllers, ensuring optimal biological activity without wasting power.
For chemical sumps, metallurgical refinery plants, and coal preparation plants, the vertical submerged slurry pumps and TZJ series handle high-viscosity, abrasive slurries with high density. Using specialized wear-plates and back-vanes, these pumps reduce recirculation and mechanical wear within the pump casing.
For chemical and food processing plants that handle bulk flour, cement, alumina, or plastics, our Roots blowers and specialized dry bulk truck blowers supply continuous, dry, oil-free high-pressure air stream. They prevent pipeline blockages, maintaining steady product flow and process control.




Beyond producing individual mechanical units, we specialize in high-efficiency MVR (Mechanical Vapor Recompression) Evaporation, Concentration, and Crystallization systems. MVR technology recycles latent heat from waste steam by compressing vapor with a high-pressure centrifugal blower, drastically lowering utility bills for zero liquid discharge (ZLD) plants.
We provide full-scope environmental turnkey contracting, including the installation, testing, and operations of biological municipal sewage plants and specialized industrial water treatment projects. By uniting hardware manufacturing, system automation, and remote telemetry, we deliver unified engineering services that maximize reliability and ensure regulatory compliance.

In-depth technical answers addressing common engineering queries regarding system performance, installation, and selection.
Inline centrifugal fans and blowers align their inlets and outlets along a single axis, allowing them to install directly into straight ducting systems. This linear layout reduces pressure losses caused by sharp directional changes, minimizes overall installation space, and simplifies structural support requirements. Offset configurations, by contrast, feature 90-degree intake-to-discharge paths, which require more space and complicate system layout.
Our Magnetic Suspension Centrifugal Blowers use active magnetic bearings (AMB) that suspend the high-speed rotor shaft in a magnetic field without physical contact. The system uses real-time sensors to track rotor position thousands of times per second, dynamically adjusting the electromagnets to prevent contact. Because there are no bearings or gears touching, the system requires no lubricating oil. This delivers completely oil-free compressed air, eliminates wear, and lowers maintenance costs.
Silicon Carbide (SiC) ceramics provide exceptional hardness, second only to diamond. This makes them highly resistant to abrasion from sharp sands, tailings, and corrosive media that quickly erode hard metal alloys (such as High-Chrome). In highly abrasive environments, our TZJK-TD Ceramic Slurry Pumps can outlast standard metal pumps by 3 to 5 times, helping facilities reduce maintenance downtime and lower their total cost of ownership.
Roots blowers use positive displacement, which can waste energy through slippage and heat at higher pressures. Centrifugal blowers utilize dynamic pressure, which is highly efficient when operating within its designed performance window. Upgrading a municipal aeration tank from old Roots blowers to modern Magnetic Suspension Centrifugal Blowers typically yields energy savings of 20% to 35%. This high efficiency helps facilities recover their initial capital investment quickly.
In Mechanical Vapor Recompression (MVR) systems, the low-pressure waste steam generated by evaporation is not condensed. Instead, a specialized high-efficiency centrifugal blower compresses the vapor, raising its pressure, temperature, and heat content. This compressed steam is then recycled back to heat the evaporator, reusing its latent heat. By recycling energy rather than venting it, MVR systems can cut thermal energy costs by up to 90% compared to multi-effect distillation setups.
