Explore our leading range of high-efficiency pumps, direct-drive blowers, and custom slurry handling parts engineered to maximize operational longevity and process efficiency.
Within modern heavy industrial processing, the demands of coal washing plants, flotation processes, and tailings management require engineering that handles highly abrasive, dense, and chemically reactive mediums. The Magnetic Tailings Pump is critical in retrieving heavy minerals, managing dense magnetite-heavy suspensions, and conveying waste materials away from the processing environment to tailing storage facilities (TSFs).
These specialized pumps must withstand intense mechanical scouring, hydrodynamic cavitation, and the persistent magnetic drag forces exerted by fine magnetite matrices. As regulatory landscapes shift toward zero-liquid discharge (ZLD) and strict environmental oversight, manufacturers like Shandong Zhangqiu Blower Co., Ltd. (ZCBC) are redefining industrial pumps through composite ceramic alloys, predictive maintenance IoT systems, and high-efficiency fluid dynamics.
By focusing on "information gain" engineering parameters—such as mechanical seal resilience, thermal heat dissipation, and optimized impeller geometry—we enable operators worldwide to improve uptime while lowering total cost of ownership (TCO).

Shandong Zhangqiu Blower Co., Ltd. (formerly known as Shandong Zhangqiu Blower Works) is an industry-leading manufacturer with over 50 years of blower design, manufacture technology, and experience. Rooted in structural excellence, the company was publicly listed on the Shenzhen Stock Exchange on July 7, 2011, under the Stock Code: 002598. This represents a significant milestone in our history, establishing ZCBC as a highly transparent, well-capitalized market leader.
Currently, our overall development strategy is to "Develop main business, pioneer new fields and innovate, cooperate to be a great company." Our foundational work concept is "Do the best." As a modern enterprise, we integrate the design, manufacturing, and sales of a wide array of industrial assets, including Roots Blowers, Centrifugal Blowers, industrial fans, heavy-duty industrial pumps, pneumatic conveying systems, electrical equipment, MVR evaporation, concentration and crystallization systems, and environmental wastewater treatment systems.
In 2005, we expanded our operations to our newly built, modern industrial park. This facility covers an area of 430,000 m², providing complete manufacturing, testing, and R&D facilities alongside a magnificent office building designed to support international clients. As of 2020, the parent company of Zhang Drum achieved an operating income of 1.5 billion yuan and a profit of 150 million yuan. ZCBC maintains 20 holding companies and operates four manufacturing bases across Jiangsu Wuxi, Guangdong Dongguan, Hunan Chenzhou, and Gansu Jinchang, with four specialized R&D centers in Beijing, Shanghai, Shijiazhuang, and Wuxi.
Industrial components must perform under varied environmental conditions, geographical pressures, and regulatory mandates. The application of Magnetic Tailings Pumps and clean coal systems varies by region, requiring localized adaptations:
Water scarcity dictates that tailings be pumped at high densities to recover and recycle up to 90% of process water. Our slurry pumps and ceramic-lined variants handle high-viscosity thickener underflows, minimizing water waste and meeting dry-stack tailings standards.
High elevation causes low atmospheric pressure, which can lead to pump cavitation and low blower discharge pressures. The ZZ Series Roots Blowers are engineered to maintain high-pressure pneumatic conveying of raw coal and dry bulk without derating efficiency.
Submerged operations in highly acidic environments call for materials that resist both corrosion and abrasion. The Famous Vertical Slurry Pump features specialized natural rubber and high-chrome alloy wet ends to withstand variable pH levels and abrasive solids.
Stricter noise and vibration standards near populated areas require quiet machinery. Our Air Foil Bearing Turbo Blowers run oil-free and generate low acoustic profiles, maintaining compliance with urban environmental codes.
In response to global demands for carbon neutrality and operational efficiency, ZCBC is advancing a roadmap focused on three key areas:
By integrating silicon carbide (SiC) and ceramic matrix composites, we aim to extend the service life of impellers, volutes, and throatbushes in high-velocity slurry pumps. This reduces replacement cycles, minimizing maintenance costs for plant operators.
Moving away from traditional belts and gearboxes, we are implementing permanent magnet synchronous motors (PMSM) across our product lines, including blowers and slurry pumps. This transition reduces drive-train losses and increases overall energy efficiency.
Equipping pumps with acoustic, vibration, and temperature sensors allows for real-time monitoring. Machine learning models analyze this data to predict seal failure or impeller wear, enabling preventative maintenance and reducing unplanned downtime.
As the executive director unit of the China General Machinery Industry Association's Fan Branch, and a primary drafter of national standards for Roots Blowers, ZCBC maintains a leading position in domestic and international turbomachinery engineering. Our strong research and development capabilities are supported by advanced processing and testing equipment, placing us at the forefront of the machinery industry.
Our product development and design center is equipped with analytical instruments and testing facilities, including nearly 100 sets of advanced machinery: CNC machining centers, five-axis machining centers, three-axis measuring instruments, CNC machine tools, and ultrasonic flaw detectors imported from Japan and Germany. We utilize Product Lifecycle Management (PLM), Computer-Aided Process Design (CAPP), and Computer-Aided Testing (CAT) systems to accelerate design cycles and improve manufacturing accuracy.
Over the years, we have developed technologies in countercurrent cooling, blower noise reduction, anti-sticky wear protection, two-stage tandem configurations, and grease lubrication systems. ZCBC has been authorized with 69 patents (including 5 invention patents) and holds 2 software copyrights. Our management systems are certified under ISO9001 (Quality), ISO14001 (Environmental), ISO50001 (Energy), and ISO10012 (Measurement).
Global mining operations require stable supply chains to avoid costly disruptions. ZCBC provides supply chain resilience through its integrated casting and machining ecosystem.

By maintaining a database of custom designs via our PLM software, we can quickly produce and dispatch drop-in replacements for standard components, minimizing downtime and supporting continuous operations.
Understanding the details of slurry dynamics, wear mechanisms, and system optimization helps operators improve performance. Here are answers to common technical queries:
Magnetic tailings often contain residual magnetite or ferrosilicon particles, which can aggregate under magnetic fields and form abrasive clusters. This behavior accelerates localized wear on impellers and liners compared to silica slurries. Our design uses high-chrome and ceramic-lined alloys to resist this compound wear, while open impeller configurations help prevent material buildup near the expeller.
Ceramic slurry pumps utilize silicon carbide composite liners that provide superior hardness (second only to diamond). This provides excellent resistance against both high-velocity particle abrasion and chemical corrosion (pH 0 to 14), outlasting high-chrome alloys by 3 to 5 times in severe applications.
Our engineering team can supply 3D CAD files and detailed drawings within 24 hours of receiving a query. Using advanced PLM software, we can match and manufacture custom shafts, impellers, and wear plates that drop directly into existing slurry pump configurations, simplifying retrofits.
In coal preparation plants, clean coal requires continuous drying and flotation. Our Roots blowers (such as the ZG or ZR series) provide high-volume, high-pressure aeration air for froth flotation cells. Additionally, our heavy-duty blowers are used in pneumatic conveying systems to transport pulverized coal safely across processing loops.
We perform full material verification, ultrasonic flaw detection, and dynamic balancing on all shafts and impellers. Each batch of high-chrome or ceramic castings undergoes microstructure analysis to ensure wear resistance, backed by testing data from independent third-party laboratories.
