Engineered for high-density, abrasive, and corrosive medium transport with exceptional thermodynamic and wear characteristics.
Founded in 1957, Shandong Zhangqiu Blower Co., Ltd. (formerly known as Shandong Zhangqiu Blower Works) has accumulated over 50 years of design, manufacturing, and process technology experience in heavy-duty flow and pressure control systems. We have expanded our strategic reach by establishing two Sino-Japanese joint ventures and an American subsidiary, making us the first enterprise in China's industrial blower industry to build an overseas branch.
Listed on the Shenzhen Stock Exchange (Stock Code: 002598) in July 2011, we stand as the leading industrial enterprise in our region. With a total modern industrial park spanning over 430,000 m², our annual operating income reached 1.5 billion yuan in 2020. Our market occupancy ranks at the top of the domestic market for Roots Blowers, while our innovative development program spans across multiple key sectors including heavy-duty slurry pumps, desulfurization pumps, wastewater treatment, MVR evaporation, and pneumatic conveying equipment.

We provide system-level engineering designs that integrate hydraulic transportation pipelines, centrifugal pump stations, and air-flow processes to maximize processing efficiency.
Under extreme slurry conditions, such as transporting gold, copper, iron ore tailings, or underflow slurries, standard metal pumps suffer catastrophic failure. Our TZJK-TD series ceramic slurry pumps resist mechanical abrasion and corrosion, offering up to 3 to 5 times the operational lifecycle of traditional chrome alloys.
Smelter processes demand continuous transport of high-temperature, acid-contaminated slags. Our heavy-duty slurry pumps feature advanced hydro-conveying design, minimizing thermal stresses and maximizing cavitation prevention (NPSHr optimisation) for uninterrupted smelting workflows.
Handling coarse refuse slurries and heavy media cyclone feeds requires high-impeller-clearance hydraulics. Our custom wet-end components prevent blockage and withstand high particle velocities, reducing operational downtime in major coal washing plants.

As ore grades decline globally, processing operations must handle higher densities of solid particulates. To prevent rapid abrasive damage, our technical roadmap focuses on three key innovations:

Our centralized manufacturing ecosystem in Shandong, Wuxi, Dongguan, Chenzhou, and Jinchang ensures complete control over raw material procurement, precision casting, machining, dynamic balancing, and performance testing.
By leveraging state-of-the-art five-axis CNC machining centers, automated casting lines, and the world's most advanced Product Lifecycle Management (PLM) system, we drastically compress delivery times while keeping production costs low. This vertical integration allows us to supply global procurement departments with premium-grade equipment at highly competitive prices.
We meet the stringent safety and ESG compliance criteria required by international mining operations, engineering firms, and municipal project contractors.
Every industrial pump and turbo system produced at our facilities undergoes standard testing protocols to meet CE, ISO, and mining safety standards. Our patents in countercurrent cooling, fan noise reduction, anti-sticky wear, and special sealing technologies ensure our systems deliver optimal safety and efficiency.
Note: Images show certified copies of our ISO9001, CE, Safety, and Patent awards.
We believe that sustainable industrial innovation starts with engineering talent. Shandong Zhangqiu Blower has built a world-class R&D organization consisting of senior engineers, researchers enjoying the State Council's special allowances, and Jinan City "5150" program doctors. We operate a dedicated "postgraduate workstation" in close cooperation with top-tier universities including Tsinghua University, Xi'an Jiaotong University, China University of Mining and Technology, and Shandong University.
Our core philosophy, "Do the best", drives our engineering teams to continuously break design records for high-pressure Roots blowers, multistage centrifugal blowers, and ceramic slurry transport pumps. This collaborative academic framework provides a reliable technical foundation for our future fluid machinery breakthroughs.

To better serve the international mining and industrial sectors, we operate localized customer support channels through our US subsidiary, Sino-Japanese joint-venture facilities, and partners in over 70 countries. Our sales, technical support, and spare parts supply networks deliver uninterrupted operation for critical infrastructure.
"Cohesion produces strength, unity brings glory. Success is just a comma; the highest mountain is always in our mind..."
Guided by Chairman Fang Rungang's vision, we cultivate a people-oriented culture that empowers engineers to create next-generation energy-saving fluid machinery.
Comprehensive engineering answers to the most common queries regarding slurry pipeline dynamics and pump selection.
A: Sintered Silicon Carbide (SiC) ceramics provide superior hardness (Mohs 9.0+) compared to high-chrome alloys. This material prevents micro-cutting and abrasive wear from hard mineral grains (quartz, iron ore, gold tailings). Additionally, SiC exhibits complete chemical inertness, making it immune to acidic or highly alkaline solutions that cause galvanic corrosion and accelerate wear in metallic pumps.
A: High solid concentration increases slurry viscosity, which raises friction losses within the pump casing and impeller. This lowers the pump's head and hydraulic efficiency while increasing the Net Positive Suction Head required (NPSHr). When selecting a pump, our engineers apply correction factors for the solid-liquid mixture density to ensure proper motor sizing and prevent cavitation.
A: Flotation frothy slurries contain trapped air, which forms air locks at the impeller eye, stopping flow. Our Foam Slurry Pumps utilize an oversized, open inlet hopper with a tangential feed design, along with an inducer blade impeller to break up the bubbles. This allows air to escape and ensures continuous pump suction.
A: Yes. Our CAD and 3D modeling engineering team can output structural and piping layouts within 24 hours of receiving system parameters. We analyze slurry velocity, pipeline friction losses, and settling velocities to optimize the installation layout and prevent pipe settling or premature wear.
A: All our manufacturing facilities operate under ISO9001 (Quality Management), ISO14001 (Environmental Management), and ISO50001 (Energy Management). In addition, our pumps carry CE markings for Europe, and our specialized models hold the official Safety Mark for Mining Products (MA), ensuring safety in underground coal mines and hazardous mineral processing zones.
We maintain strict quality control through advanced inspection machinery, ensuring every manufactured unit meets international standards before shipment.
