Pioneering standard components and heavy-duty auxiliary blowers for multi-system industrial setups.
Why modern wet processing circuits require specialized high-density slurry management systems.
In global mining, aggregate processing, and heavy industrial chemical operations, separation efficiency defines profitability. A Classification Screen Pump operates at the nexus of wet classification circuits, delivering slurries containing highly abrasive, variable-sized solids to hydrocyclones, vibrating screen classification decks, and sorting systems. Unlike standard water transport pumps, classification screen pumps must maintain a precise velocity profile to prevent premature settling while avoiding extreme shear degradation that can ruin delicate flocculated mediums.
By implementing advanced hydrodynamic impeller designs and utilizing severe-wear-resistant materials, leading manufacturers have revolutionized the reliability of these units. These pumps act as the mechanical heart of closed-circuit grinding systems, mill discharge operations, and mineral dressing circuits. When system pressure drops or flow fluctuates, the split cut-point (d50) within hydrocyclones drifts, leading to either bypass of coarse particles into the fine stream or overgrinding of pre-separated minerals. Therefore, maintaining consistent volumetric displacement under high solids loading is critical.
Analyzing regional supply chains, infrastructure demands, and structural requirements for exporters.
Characterized by strict environmental regulations regarding tailings management and water reuse. Demand focuses on energy-efficient slurry configurations and quick-maintenance pump wear parts to decrease down-time in large-scale copper and gold extraction operations.
Rapid industrialization and localized mineral extraction drives high-volume orders. Rapid lead times, local support, and cost-effective, high-reliability configurations are the key parameters defining procurement success in major mining sectors.
Europe and localized zones in South America demand strict mechanical seal integrity, low noise pollution levels, and certified explosion-proof configurations. Aligning hardware specifications with regional directives (CE, ATEX, OSHA) is non-negotiable.
Shandong Zhangqiu Blower Co., Ltd. (formerly Shandong Zhangqiu Blower Works) represents over 50 years of extensive design, manufacturing technology, and engineering experience. The enterprise has successfully established two Sino-Japanese Joint-ventures and a strategic US branch, highlighting its position as a global exporter. As the leading enterprise in the regional industry, the market occupancy of its main product—Roots Blowers—ranks at the top of the sector in China.
Following our overall developing strategy: "Develop main business, pioneer new fields and innovate, cooperate to be a great company" and acting under the professional concept of "Do the best", the corporation integrates design, manufacturing, and distribution of Roots Blowers, Centrifugal Blowers, Industrial Fans, Slurry & Industrial Pumps, Pneumatic Conveying Systems, Electrical Equipment, and MVR Evaporation systems.
How our multi-disciplinary approach connects blower, vacuum, and slurry pump lines to major industrial sectors.
Deploying specialized slurry pumps (such as the TZJ series and wear-resistant Ceramic Slurry Pumps) to transport heavy discharge from mills to classification screens and hydrocyclones under continuous run-times.
Integrating our high-efficiency Air Foil Bearing Turbo Blowers, Magnetic Suspension Blowers, and ZJQ Submerged Slurry Pumps to aeration basins, filter press feeding, and sludge dewatering units.
Leveraging the VR Series Steam Roots Compressor alongside water ring vacuum pumps for industrial crystallization setups, minimizing energy costs while maximizing operational yield.
A look into our production centers, research bases, and organizational history.
In 2005, the enterprise relocated to a high-standard modern industrial park. This facility covers an area of 430,000 m², featuring comprehensive tooling, clean testing yards, and research areas designed to foster collaboration with international partners.
In July 2011, the company achieved a critical milestone by listing on the Shenzhen Stock Exchange (Stock Code: 002598). By 2020, the parent company registered an operating income of 1.5 billion yuan and a profit of 150 million yuan. Today, the corporation holds 20 distinct subsidiaries with specialized production bases established in Wuxi (Jiangsu), Dongguan (Guangdong), Chenzhou (Hunan), and Jinchang (Gansu). Strategic R&D hubs are located across major scientific nodes in Beijing, Shanghai, Shijiazhuang, and Wuxi.
Advancing product lifecycles through PLM systems, CNC five-axis machining, and specialized material science.
Our organization has prioritized R&D, establishing a provincial-level enterprise technology center dedicated to Roots vacuum pumps, multi-stage centrifugal blowers, single-stage high-speed centrifugal systems, slurry pumps, desulfurization pumps, and pneumatic conveying equipment (such as rotary feeders and diverter valves).
Supported by a comprehensive Product Lifecycle Management (PLM) system, Computer-Aided Manufacturing (CAM) tools, and Computer-Aided Process Planning (CAPP), our research and production cycle matches international benchmarks. Precision machining centers, including CNC five-axis machining centers and ultrasonic flaw detection equipment imported from Japan and Germany, guarantee high manufacturing precision.
Authorized with 69 patents (including 5 core invention patents) and 2 software copyrights. Specialized developments include countercurrent cooling systems, wear-resistant anti-sticky impeller surfaces, low-noise casing geometries, high-temperature seals, and grease-lubricated bearing configurations.
Partnering with academic institutions to construct highly reliable fluid systems.
By establishing a dedicated "Postgraduate Workstation" and cooperating with universities such as Tsinghua University, Xi'an Jiaotong University, China University of Mining and Technology, and Shandong University, our design team stays at the forefront of fluid dynamics innovation. Our engineering team can supply specialized CAD designs and 3D configuration models within 24 hours.
The manufacturing units maintain ISO9001 (Quality Management), ISO14001 (Environmental Standards), ISO50001 (Energy Management), and ISO10012 (Measurement Management) system certifications. Product series conform to CE standards, national energy-saving benchmarks, and carry official Safety Marks for Mining Products.
Targeting distinct physical slurry requirements across challenging industrial process lines.
Standard slurry pumps fail when handling entrained air bubbles, leading to air-binding and surging. Utilizing specialized Foam Slurry Pumps stabilizes the fluid intake, assuring consistent delivery to downstream sizing screens without pump airlocks.
Handling tailing underflows containing coarse, sharp particles requires advanced materials. The application of Ceramic Slurry Pumps (TZJK-TD Series) offers high wear resistance, expanding pump service life relative to high-chrome alloys.
Draining deep sumps laden with heavy mineral sediment poses suction problems. The ZJQ Submerged Slurry Pump functions directly in the fluid medium, using mechanical agitators to fluidize settled solids and maintain flow rates to the classification screens.
Providing technical information on sizing, material selectability, and operational optimization.
Heavy-duty slurry pumps, multi-stage roots blowers, and vacuum systems for demanding fluid-handling processes.
To support buyers, Shandong Zhangqiu Blower Co., Ltd. runs dedicated logistics pathways, international trading units, and localized field offices in North America and across key European sectors. The products are regularly exported to the United States, Germany, Italy, Russia, Australia, and over 70 other countries and regions.
