Explore our leading machinery lineup designed to match high-abrasion working environments, integrated directly with advanced wear-resistant metallurgy.
In modern industrial processing—especially within mining beneficiation, coal washing, wastewater management, and chemical evaporation—slurries carrying highly abrasive and corrosive particulate matters cause extreme material erosion. Equipment failure in these environments usually stems from the degradation of wet-end parts.
Front Wear Plates (Protection Plates) serve as the first line of defense inside heavy-duty centrifugal slurry pumps and pneumatic conveying chutes. By utilizing high-chromium cast iron alloys, silicon carbide ceramics, and composite hardfacings, wear plates directly absorb the kinetic impact and shear forces of turbulent fluids, protecting the main pump casing and preserving internal hydraulic efficiency.
Without high-grade protection plates, internal recirculation increases exponentially as clearances widen. This leads to massive drops in efficiency, higher power draw, and catastrophic shell-through wear. Our design integrations focus precisely on solving this tribological challenge.
Delivers exceptional resistance to high-stress gouging abrasion. Perfect for heavy mineral slurry handling and coarse tailing pipelines.
Provides unparalleled hardness (exceeding 9.5 Mohs) and works flawlessly in extremely corrosive chemical slurries where metals quickly dissolve.
Designed with adjustable front shims to maintain tight tolerances against the impeller, keeping pump efficiency at peak levels for longer cycles.
Formerly known as Shandong Zhangqiu Blower Works, we are an industry leader with over 50 years of blower and pump design, manufacturing technology, and deep experience. ZCBC has successfully established two Sino-Japanese Joint-ventures and a dedicated USA branch, marking us as the pioneering company in the Chinese blower industry to set up overseas operations.
Listed on the Shenzhen Stock Exchange (Stock Code: 002598) in July 2011, we have built a monumental modern industrial park covering 430,000 square meters. Our multi-faceted engineering portfolio encompasses Roots Blowers, Centrifugal Blowers, Industrial Pumps, Pneumatic Conveying Systems, MVR Evaporators, and High-Wear Component Casting.
With an annual operating income exceeding 1.5 billion yuan and active R&D centers in Beijing, Shanghai, Shijiazhuang, and Wuxi, ZCBC delivers unmatched technological capabilities to partners worldwide.
Combining state-of-the-art Japanese manufacturing methodologies with China's robust industrial supply chain leads to peerless performance-to-cost ratios.
Our workshops house nearly 100 sets of advanced processing equipment. This includes CNC machining centers, five-axis machining tools, and coordinate measuring instruments imported from Japan and Germany. We hold critical clearance tolerances under 0.05mm, crucial for maximizing hydraulic efficiency and reducing wear plate turbulence.
By owning our alloy casting foundry, we control the entire metallurgical process of front wear plates. From raw ingot mixing to heat treatment and final machining, we guarantee the exact distribution of chromium carbides (Cr7C3) throughout the matrix, eliminating the quality variances common to outsourced casting factories.
Our dedicated design team provides custom 3D drawings within 24 hours of receiving draft measurements or wear pattern photographs. Supported by PLM (Product Life Cycle Management) and CAM systems, we cut down prototyping and mass-production lead times by more than 40% compared to Western competitors.
Different industrial processes present unique tribological stress configurations. Understanding these environments is the key to selecting the correct protection plate material:
| Material Class | Hardness (HRC / Hv) | Primary Application Scenario | Key Strengths | Corrosion Resistance |
|---|---|---|---|---|
| High-Chromium Alloy (27% Cr) | HRC 58 - 62 | Gold tailings, mining, heavy slurry pumps | Excellent gouging & sliding wear resistance | Moderate (pH 4 - 10) |
| Hypereutectic Alloy (30%+ Cr) | HRC 62 - 66 | Coal washing, fine sand extraction | Ultra-hard carbide matrix, low abrasion rate | Good (pH 3 - 12) |
| Silicon Carbide Ceramic Composite | Hv 2200 - 2500 | Flue gas desulfurization (FGD), chemical MVR | Immune to acidic erosion and rust degradation | Outstanding (pH 1 - 14) |
| Tungsten Carbide Overlay (Hardfacing) | Hv 1200 - 1500 | High velocity sand slurry pipelines | Extreme localized protection, impact dampening | Good |
Our commitment to technical innovation is verified by international certification bodies and a wide patent portfolio.
In recent years, the company has secured a number of proprietary technologies including countercurrent cooling, fan noise reduction, fan anti-sticky wear, two-stage tandem configurations, smart industrial fan automation, specialized mechanical sealing, advanced grease lubrication systems, and twisted-leaf impeller designs.
ZCBC is authorized with 69 patents (including 5 invention patents) and 2 software copyrights. Furthermore, we are certified in accordance with:









Purchasing managers in mining conglomerates and EPC enterprises need to evaluate more than just the initial price tag. True value is realized by minimizing Total Cost of Ownership (TCO).
Purchased wear plates must match standard pump models (like Warman® or other standard slurry pumps) down to the millimeter. Our parts match standard OEM drawings and are guaranteed to fit without causing localized turbulence or structural stresses.
Unqualified suppliers often cut costs by reducing Chromium or Carbon content. This leads to soft, ineffective wear plates. ZCBC provides full chemical analysis certificates and physical hardness reports with every single batch shipped.
Industrial operations run 24/7/365. With physical branches in the US and distributors across 70+ countries, ZCBC ensures that urgent replacement parts are delivered quickly, protecting your operations from costly downtime.
Corporate culture is the soul of a large enterprise and a reflection of its management maturity. At ZCBC, we fully respect the value of our workforce, cultivate the individual potential of each employee, and maintain a shared sense of pride and ownership.
"Cohesion produces strength, unity brings glory. Success is just a comma, the highest mountain is always in Zhang Gu people's mind..."
Under the guidance of Chairman Fang Rungang and our leadership team, ZCBC operates on a simple guiding concept: "Do it, do the best." This means deploying first-class design and R&D personnel, utilising the finest manufacturing equipment, and maintaining responsive after-sales service to ensure our customers' needs are fully met.

In 2005, ZCBC relocated to a modern industrial park equipped with high-standard facilities. Spread across 430,000 square meters, the park features a dedicated office building and spacious workshops designed for collaborative projects with international partners.
By 2020, our parent company achieved an annual operating income of 1.5 billion yuan, with a profit of 150 million yuan across our holding companies. ZCBC currently manages 20 holding companies and operates four production bases in Wuxi (Jiangsu), Dongguan (Guangdong), Chenzhou (Hunan), and Jinchang (Gansu). These are backed by our advanced R&D centers in Beijing, Shanghai, Shijiazhuang, and Wuxi.
Through our dedicated foreign trade company and US branch, ZCBC's products are exported to over 70 countries and regions, including the United States, Germany, and Italy. Looking forward, we continue to expand our operations across three primary industrial pillars: intelligent manufacturing, environmental water treatment, and new materials development.
