Engineered for high efficiency, operational resilience, and heavy-duty industrial processing environments.
As the economic driver of Vietnam, Ho Chi Minh City (HCMC) is witnessing an unprecedented transition from low-tech manufacturing to heavy industrial processing, advanced chemical synthesis, and intensive municipal modernization. The industrial zones of Cat Lai, Hiep Phuoc, and Tan Thuan are leading this shift, requiring massive upgrades in municipal wastewater management, mining operations, and bulk material transport.
The local industrial status demands advanced technology to combat severe abrasion caused by dense silt, corrosive process waters, and high ambient temperatures. The integration of high-performance pumps and blowers is no longer just an upgrade—it is a critical requirement for maintaining continuous operational safety and achieving decarbonization goals set by the Vietnamese government.
A publicly listed manufacturing powerhouse (Stock Code: 002598) with over 50 years of technological experience.
Shandong Zhangqiu Blower Co., Ltd. (Formerly named: Shandong Zhangqiu Blower Works) is a company with over 50 years’ blower design, manufacture technology, and experience. We set up two Sino-Japanese Joint-ventures and one USA branch, becoming the first company in the Chinese blower industry to establish an overseas branch. We are the leading enterprise in the local Zhangqiu industry, and our main product, the Roots Blower, ranks top in market occupancy in China's blower industry.
Our overall developing strategy focuses on: “Develop main business, pioneer new fields and innovate, cooperate to be a great company”. Guided by our core working concept, “Do the best”, we have evolved into a highly modern enterprise that integrates design, manufacturing, and sales of: Roots Blowers, Centrifugal Blowers, Fans, Industrial Pumps, Pneumatic Conveying Systems, Electrical Equipment, MVR Evaporation systems, Concentration and Crystallization systems, and Waste Water Treatment Products.
In 2005, the company relocated to a newly built, high-standard modern industrial park. This facility covers an area of 430,000 m² with complete research and production capabilities. On July 7th, 2011, the company was publicly listed on the Shenzhen Stock Exchange (Stock code: 002598), achieving a monumental development milestone.
By 2020, our parent company realized an operating income of 1.5 billion yuan and a profit of 150 million yuan. Currently, the company manages 20 holding companies and four primary manufacturing bases located in Jiangsu Wuxi, Guangdong Dongguan, Hunan Chenzhou, and Gansu Jinchang, supported by dedicated R&D centers in Beijing, Shanghai, Shijiazhuang, and Wuxi.
Global engineering capabilities backed by rigorous quality standards and heavy capitalization.
Modern industrialization requires a rigorous understanding of fluid dynamic machinery. In municipal aeration, pneumatic powder transport, and heavy mining, systems like the **TZJ Series Slurry Pump** and advanced **Roots Blowers** form the backbone of processing infrastructure. This section provides an analytical breakdown of these systems, optimizing for long-term mechanical reliability and energy performance.
| Equipment Class | Core Application | Material Configuration | Efficiency Benchmarks |
|---|---|---|---|
| TZJ Slurry Pump | Abrasive tailing handling & mining runoffs | High-Chrome Alloy (Cr27+) / SiC Ceramic Liners | Hydraulic efficiency up to 86% |
| Air Foil Bearing Blower | Municipal biological sewage aeration | Aviation-grade aluminum, Oil-free bearing | Saves 30% energy compared to Roots standard |
| Two-Stage Roots Blower | High-pressure chemical gas conveying | Cast iron integral rotors, specialized seals | Up to 100 kPa pressure differential |
| Ceramic Slurry Pump (TZJK) | Acidic chemical slurry transport | Reaction-sintered silicon carbide matrices | 3x lifespan compared to structural steel |
Slurry handling in chemical and mineral extraction zones is highly destructive to impeller and liner components. The **TZJ Series Slurry Pump** addresses this challenge through advanced metallurgy and material science. Standard components feature high-chromium iron alloys, containing up to 27% chromium (Cr27), which exhibits outstanding resistance to erosion-corrosion. For chemical streams where pH swings are common, our proprietary **Silicon Carbide (SiC) Ceramic Slurry Pumps** utilize reaction-sintered silicon carbide matrices. This provides a hard barrier against abrasive solids, increasing the mean time between maintenance cycles from months to years.
Aeration blowers typically account for 50% to 70% of the energy consumed by biological wastewater treatment systems. In HCMC’s high-capacity treatment plants, selecting the correct blower design is critical. Roots blowers represent a positive displacement approach, maintaining constant volumetric flow rate against fluctuating system pressures. This makes them ideal for deep-tank aeration and pneumatic conveying.
For large-scale, continuous-load systems, **Air Foil Bearing Turbo Blowers** leverage oil-free aerodynamic levitation technology. The elimination of gearboxes and lubricant circuits minimizes frictional losses, resulting in a significantly lower lifetime carbon footprint. Combined with Variable Frequency Drives (VFDs), these turbo blowers match air delivery to real-time dissolved oxygen demand, optimizing energy consumption.
With massive machining centers, including German five-axis milling machines and Japanese CNC routers, Shandong Zhangqiu Blower guarantees micron-level tolerance on impellers and rotors. This precision prevents internal gas slip in blowers and reduces hydraulic recirculation in pumps. Because the factory owns its production processes—from casting to final dynamic balancing—the cost-performance ratio surpasses that of European manufacturers, offering a direct financial benefit to regional procurement teams in Vietnam.
Our commitment to quality is backed by comprehensive industry certifications. Shandong Zhangqiu Blower is a third-level enterprise for safety production standardization. We hold **ISO9001** quality system certification, **ISO14001** environmental management system certification, **ISO50001** energy management system certification, and **ISO10012** measurement management system certification. Our products comply with CE standards, safety marks for mining products, and Chinese national energy conservation directives. These standards guarantee that all heavy-duty equipment delivered to Ho Chi Minh City complies with both international benchmarks and domestic Vietnamese safety requirements.
Our company possesses strong scientific and technological research and development capabilities, supported by advanced processing and testing equipment. Our design, research, development, and testing processes lead the domestic machinery industry. The company operates a first-class product development and design center, utilizing over 100 sets of advanced equipment, including CNC machining centers, five-axis machining centers, three-axis measuring instruments, and ultrasonic flaw detectors imported from Japan and Germany.
We leverage Product Lifecycle Management (PLM), Computer-Aided Process Planning (CAPP), Computer-Aided Manufacturing (CAM), CNC technology, and Computer-Aided Testing (CAT) to improve manufacturing precision and shorten product development cycles.
Through robust incentive programs, we have built a research team of senior engineering experts, Jinan City "5150" project doctorates, and specialists receiving State Council allowances. We operate a dedicated postgraduate workstation and collaborate closely with top-tier universities, including Tsinghua University, Xi'an Jiaotong University, China University of Mining and Technology, and Shandong University, to drive continuous product innovation.
