View Technical Specifications →South Africa’s industrial landscape is uniquely demanding. As home to the world's deepest mining operations—spanning the extensive gold networks of the Witwatersrand Basin, the rich platinum group metals (PGM) of the Bushveld Igneous Complex, and the dense coal beds of Mpumalanga—the nation presents unmatched engineering challenges. Mining at depth requires heavy-duty pumps capable of handling highly abrasive, variable-viscosity mixtures containing quartz, pyrites, and other dense crystalline solids.
Within this ecosystem, vertical slurry pumps play an essential role. Sump drainage, tailings management, froth recovery, and process plant wastewater treatment demand pump solutions that do not succumb to mechanical seal failure, shaft deflection, or localized abrasive wear. Crucially, South Africa's ongoing power supply constraints (such as load shedding) necessitate hydraulic designs that optimize efficiency and reduce starting currents under variable frequency drive (VFD) setups, ensuring system resilience during power grid instability.
Globally, mining operations are shifting toward high-density and paste backfill technologies to minimize water consumption and tailing dam risks. This shift demands vertical and horizontal pumps configured for high-viscosity and high-specific-gravity non-Newtonian mixtures without clogging.
Traditional elastomers are being replaced by high-chrome hypereutectic alloys (such as Cr27+) and specialized ceramics. These materials are engineered to withstand continuous impact from sharp-edged mineral particulates under acidic or high-alkaline chemical matrices.
Modern process plants demand remote structural health monitoring. Integrating vibration sensors and temperature transducers in the upper shaft and bearing assemblies of vertical pumps helps prevent catastrophic failures and enables predictive maintenance planning.
Shandong Zhangqiu Blower Co., Ltd. (formerly Shandong Zhangqiu Blower Works) is a globally recognized manufacturing force with over 50 years of design, manufacturing, and technological experience in industrial blowers and pump systems. Demonstrating international leadership, ZCBC set up two Sino-Japanese joint ventures and established a dedicated USA branch, becoming the first company in China's blower industry to establish an overseas operational branch.
As a leading enterprise in China's industrial manufacturing sector, our primary products, including Roots Blowers, maintain leading market share. Our overall development strategy focuses on driving growth in core divisions, pioneering new technological fields, and fostering long-term global collaboration. Operating under the philosophy of "Do the best," ZCBC is a modernized enterprise integrating the design, manufacture, and sales of Roots Blowers, Centrifugal Blowers, Heavy-Duty Industrial Slurry Pumps, Pneumatic Conveying Systems, Electrical Control Equipment, and MVR Evaporation systems.
In 2005, the company relocated to a modern, high-standard industrial park covering 430,000 m², which provided the physical capacity needed to expand production and strengthen international collaborations. ZCBC listed on the Shenzhen Stock Exchange on July 7th, 2011 (Stock Code: 002598), securing a strong capital foundation for ongoing technological expansion.
By 2020, the parent company achieved operating income of 1.5 billion yuan and a profit of 150 million yuan. ZCBC operates 20 holding companies and has established four manufacturing bases in Wuxi (Jiangsu), Dongguan (Guangdong), Chenzhou (Hunan), and Jinchang (Gansu). These operations are supported by four dedicated R&D centers in Beijing, Shanghai, Shijiazhuang, and Wuxi.
Vertical slurry pumps must withstand abrasive mineral particles, chemical wear, and erratic flow rates. Our vertical cantilevered design eliminates submerged bearings and shaft seals, addressing a common vulnerability in sump pumps. This configuration ensures reliable operation under snoring conditions without mechanical failure.
No submerged bearings or mechanical packing seals are used. This layout eliminates bearing contamination from abrasive slurry ingress, reducing maintenance requirements and down-time.
Available in high-chrome alloys, natural rubber, and polyurethane liners to match specific operational conditions, from coarse gold tailings to acidic copper wash liquids.
Induced-flow double suction impellers minimize axial thrust, reducing vibration and wear on the heavy-duty drive bearings housed above the sump level.
Provides dependable, oil-free air delivery ideal for wastewater aeration, flotation systems, and industrial pneumatic conveying lines.

ZCBC provides complete, integrated systems engineered to optimize operations across key processing stages:
In PGM and gold recovery, flotation cells require continuous low-pressure air supply to generate uniform bubbles. By combining ZCBC Roots or Centrifugal Blowers with our foam slurry pumps, processing plants can maintain optimal bubble distribution and froth transport, reducing ore loss and maximizing recovery rates.
As water resources become more limited, mining operations must implement conservation strategies. ZCBC delivers integrated MVR (Mechanical Vapor Recompression) Evaporation, Concentration, and Crystallization systems that recover process water from saline mine drainage, allowing plants to achieve zero liquid discharge.
Practical solutions to common fluid-handling and engineering challenges faced by mine operators in South Africa and globally.
Standard submersible pumps house the motor and bearings within a sealed enclosure below the liquid surface, exposing them to potential seal failures and abrasive contamination. ZCBC's vertical cantilevered pumps place all bearings, seals, and motor components above the liquid line, utilizing a rigid, unsupported shaft. This design eliminates submerged sealing mechanisms, enabling the pump to run dry or operate under snoring conditions without mechanical damage.
For abrasive and acidic applications (typically low-pH tailings with high silica content), we recommend natural rubber or polyurethane liners paired with high-chrome alloy impellers (ASTM A532 Class III Type A, Cr27). In highly acidic conditions (pH < 3), specialized duplex stainless steels or ceramic components are used to resist both chemical corrosion and mechanical erosion.
Froth accumulation can lead to air-binding in standard impellers, resulting in loss of prime. To address this, ZCBC designs specialized open impellers and conical sumps with tangential inlets. These configurations utilize centrifugal force to separate entrained air from the slurry before it reaches the impeller eye, ensuring continuous flow in flotation operations.
To minimize energy consumption and protect equipment during power fluctuations, installations should utilize Variable Frequency Drives (VFDs) paired with high-efficiency IE3 or IE4 motors. VFDs reduce starting current spikes on weak power grids. Additionally, installing automatic check-valves and emergency dump lines prevents slurry backflow and solids settling in the pump casing during unexpected power cuts.
