As the executive director of the China General Machinery Industry Association and the vice president unit of the Fan Branch, we lead domestic technological breakthroughs and act as a pivotal board member of the China International Turbomachinery Industry Alliance Council.
Modern industrial processing requires handling complex, abrasive, and corrosive multi-phase fluids. Standard metal alloys often suffer from aggressive erosion-corrosion. Zhanggu’s technological roadmap directly addresses this through advanced structural design, material science breakthroughs, and digital integration.
By transitioning from high-chromium alloys to sintered silicon carbide (SiC) and structural ceramics, our TZJK-TD series ceramic slurry pumps achieve a Mohs hardness score exceeding 9.2. This material science upgrade delivers up to 4x-6x the wear lifetime of conventional steels in abrasive, high-grit environments.
Using state-of-the-art Computational Fluid Dynamics (CFD), our engineering design team optimizes flow velocities and pressure gradients within the pump casing. This minimizes interior turbulence, reduces recirculation losses, and matches the Net Positive Suction Head (NPSH) requirements perfectly to lower cavitation risk.
We are integrating real-time telemetry into our industrial pumping assemblies. Vibration sensors, heat indicators at the bearing assemblies, and mechanical seal pressure transducers stream telemetry data directly to SCADA systems, providing preventive maintenance alerts before critical failures occur.
Zhanggu integrates component engineering with holistic processing solutions, providing turnkey systems for heavy industries globally.
In minerals classification, flotation, and tailing discharge operations, slurry pumps must run non-stop. Our ceramic and vertical submerged pumps process high-density mineral slurries, sand mixtures, and abrasive ores, maintaining high volumetric efficiency and minimizing downtime.
Power plants and environmental municipal projects run highly corrosive limestone slurries for sulfur removal. Our chemical-resistant ceramic and alloy pumps handle corrosive environments with ease, supported by our efficient aeration blowers for wastewater biological treatments.
Our modern industrial park, built in 2005 and spanning 430,000 m², represents a major milestone in China’s heavy machinery manufacturing.

Get professional insights on heavy industrial blowers, slurry pumps, and material selection criteria from our engineering experts.
Ceramic slurry pumps, such as the TZJK-TD series, utilize sintered silicon carbide (SiC) or composite ceramic materials with a Mohs hardness of 9.2, which is significantly harder than standard high-chromium alloys (typically 5 to 6 on the Mohs scale). This allows the pump to handle abrasive and corrosive slurries with minimal surface wear, extending the system's service life up to 4 to 6 times compared to metal alloys and maintaining consistent hydraulic efficiency.
Sizing requires analyzing flow rates, target head pressure, solid concentration by volume/weight, particle size distribution (d50), and fluid chemical properties. Our engineering team uses proprietary fluid dynamics software to calculate friction losses and Net Positive Suction Head (NPSH), ensuring the pump operates efficiently while minimizing wear and cavitation risks.
Our facilities are certified under ISO 9001 (Quality Management), ISO 14001 (Environmental), ISO 50001 (Energy Management), and ISO 10012 (Measurement Management). Key product lines carry CE, 3C, and specialized mining safety approvals, making them suitable for use in demanding international projects.
Roots blowers are positive displacement machines that deliver a constant volume of air against varying system pressures, making them well-suited for high-pressure pneumatic conveying and deep-tank wastewater aeration. Centrifugal blowers operate as dynamic machines, supplying variable flow rates at relatively stable pressures, which is ideal for large-volume, constant-resistance aeration processes.
Through our US branch, global offices, and distributor network, we maintain inventory for critical wear parts, including impellers, mechanical seals, and casings. We also provide engineering support, including 24-hour CAD drawings and on-site technical assistance, to help minimize plant downtime.
