Engineered for extreme wear, abrasiveness, and corrosive environments worldwide.
Within high-density, harsh processing environments, the management of highly abrasive, corrosive, and viscous media remains one of the largest engineering constraints on plant uptime. Heavy-duty slurry pumps are the crucial heart of fluid handling networks, directly impacting mining productivity, mineral dressing recovery rates, and coal preparation outputs. Selecting a premier slurry pump manufacturer represents a structural decision affecting a facility's lifecycle costs and operating efficiency.
Shandong Zhangqiu Blower Co., Ltd. (ZCBC) is a global leader in fluid dynamics, utilizing over 50 years of design engineering and manufacturing experience to produce highly integrated roots blowers, centrifugal units, and heavy-duty slurry pumps. As a listed enterprise on the Shenzhen Stock Exchange (Stock Code: 002598), ZCBC sets the global benchmark for wear resistance, optimized hydraulics, and comprehensive engineering support.
Our industrial solutions concentrate on resolving standard issues associated with high-wear slurries:
Shandong Zhangqiu Blower Co., Ltd. (formerly known as Shandong Zhangqiu Blower Works) has led the Chinese blower and heavy machinery sector for half a century. Known for manufacturing rugged Roots Blowers, our capabilities extend into custom-engineered industrial slurry pumps, desulfurization pumps, MVR evaporation plants, and complete wastewater treatment systems.
Leveraging Sino-Japanese joint ventures and a dedicated engineering branch in the United States, we are the first Chinese blower manufacturer to establish overseas branches. Our massive, high-standard modern industrial park, built in 2005, covers over 430,000 square meters. This site serves as our main production base, integrating automated design, high-precision manufacturing, and advanced testing setups.
In 2020, the parent company achieved operating income of 1.5 billion yuan, supported by 20 holding subsidiaries and four manufacturing bases in Wuxi, Dongguan, Chenzhou, and Jinchang. Our primary research hubs in Beijing, Shanghai, Shijiazhuang, and Wuxi focus on high-efficiency fluid mechanics and material science innovations.
Why leading global miners and contractors choose Chinese engineered pumping equipment.
Our factories sit within an integrated supply chain that links raw ore processing, high-chromium casting, and high-precision CNC machining. This setup lowers raw material logistics costs and ensures consistent chemical compositions for high-wear pump casings and impellers.
Our metallurgy labs construct proprietary wear alloys and silicon-carbide sintered ceramics, including those used in our TZJK-TD series. These materials match or exceed international standards for abrasive wear and impact resistance.
Through automated foundry lines and CNC operations, ZCBC reduces production cycles by 30-40%. We provide complete engineering drawing approvals within 24 hours, helping global teams hit aggressive project schedules.
Heavy-duty slurry pumping requires continuous protection against erosion and corrosion. In mineral beneficiation, tailings disposal, and flue gas desulfurization (FGD), standard cast iron pumps fail rapidly. ZCBC uses advanced material science to extend the lifespan of wet-end components, including impellers, volute liners, throatbushes, and frame plate liner inserts.
For highly abrasive slurries containing coarse particles, our High-Chromium Alloy (A05 / Cr27) features a micro-structure rich in hard eutectic carbides (approximate hardness of 60-65 HRC). This design resists micro-cutting and impact fatigue from sliding particles.
For corrosive and acidic slurries, such as those found in gold, copper, and zinc leaching, we use TZJK-TD Sintered Silicon Carbide (SiC) Ceramics. Sintered ceramics are virtually chemically inert, offering strong resistance to chemical corrosion across pH levels from 1 to 14, outlasting high alloys in combined acid-abrasive conditions.
| Material Code | Chemical/Structural Class | Hardness Range | Primary Applications |
|---|---|---|---|
| Cr27 (A05) | 27% Chromium White Iron | 600 - 650 HB | Coarse tailings, mineral concentrates, sand reclamation. |
| Cr30 (A49) | Low-carbon high-chrome alloy | 560 - 620 HB | Acidic slurries, low-pH FGD systems. |
| TZJK-TD SiC | Sintered Silicon Carbide Ceramic | > 2000 HV | High-corrosion chemical slurries, fine mineral sands. |
| Natural Rubber | High-Resilience Elastomer | 50 - 60 Shore A | Fine silica slurries, tailings without sharp edges. |
Custom engineering solutions designed to meet the strict demands of global heavy industry.
Our heavy-duty pumps handle coarse mill discharge, primary classification feeds, and cyclone feed systems. Their heavy-section walls handle high-density mineral solids without cracking.
In thermal power generation, FGD scrubber systems circulate highly corrosive limestone slurries. Our specialized ceramic pumps resist chemical corrosion and continuous particle abrasion, keeping emission control lines online.
We supply high-efficiency heavy medium circuit pumps, coal washing pumps, and tailings handling systems. These units maintain high flow rates and low energy consumption across dynamic operating profiles.
Handling high-concentration thickened tailings paste requires high-pressure capabilities. Our staged slurry pumps operate reliably under high backpressures over long distances.
ZCBC runs a first-class R&D and design center equipped with advanced development, analysis, and materials testing instruments. Our facilities feature over 100 sets of advanced processing equipment, including CNC machining centers, five-axis machining systems, coordinate measuring machines (CMMs), and ultrasonic flaw detectors imported from Japan and Germany.
We utilize Product Lifecycle Management (PLM) and Computer-Aided Manufacturing (CAM) systems, backed by Computer-Aided Process Planning (CAPP) and computer-assisted testing. This digital framework shortens design-to-production times and ensures precise component tolerances.
Our quality management systems are certified to ISO9001, ISO14001, ISO50001, and ISO10012 standards. Relevant products carry CE, Safety Mark for Mining Products, and mandatory 3C certifications, ensuring compliance with strict occupational health and environmental safety codes.




For international procurement managers, engineers, and EPC contractors, sourcing heavy equipment involves complex logistics and quality checks. ZCBC offers comprehensive services to streamline these processes and ensure project milestones are met:


Expert technical answers to standard questions about heavy-duty slurry pumps.
ZCBC provides complete engineered systems beyond stand-alone machines. In chemical concentration, industrial waste treatment, and Zero Liquid Discharge (ZLD) plants, we integrate mechanical vapor recompression (MVR) technology with our high-pressure blowers and corrosion-resistant slurry pumps.
Our MVR evaporation, concentration, and crystallization packages concentrate highly saturated inorganic salt solutions (such as sodium chloride, sodium sulfate, and ammonium sulfate). As concentration levels rise, crystallizers produce highly abrasive salt slurries. Integrating our low-speed ceramic slurry pumps with MVR systems ensures steady crystallization control and protects downstream equipment from clogging and wear.


Engineered for pneumatic conveying, aeration, and heavy-duty gas recovery.
