River Dredging and Sand Mining Pumps
River dredging and sand mining pumps are single-stage, single-suction, horizontal centrifugal pumps. They are used in on-site construction that adapts to the actual conditions of dredgers, such as installation space, dredging methods, dredging capacity, and sediment types. Featuring a large-flow design, they have strong conveying capacity and can be applied to dredging projects of different scales (e.g., dredging of small rivers or expansion of large ports).
Core Product Features
Structure
These pumps adopt a cantilever-type single-stage centrifugal structure. The high-strength bracket and simple bearing assembly are connected by bolts, resulting in a simple and reliable structure that is easy to install, disassemble, and adjust the impeller gap.
Materials
The heavy-duty flow-passing components (impellers, pump casings) are made of high-chromium cast iron, wear-resistant rubber linings, or tungsten carbide coatings, with a hardness of HRC 60+, which ensures resistance to sediment wear.
Performance
• Strong Conveying Capacity: With a large-flow design and a wide flow range 50 10,000𝑚³/ℎ, they are suitable for dredging projects of different scales (e.g., dredging of small waterways or expansion of large ports).
• High Head Performance: The single-stage head can reach 50~150 meters, and the head of some multi-stage series pumps exceeds 200 meters (e.g., for deep-sea dredging).
Company Profile
Large-Scale Advanced Manufacturing Capacity
CZME has a modern production base equipped with 126 core production lines and 34 sets of professional equipment, covering the entire production process. Twenty-three CNC machining centers ensure a machining accuracy of ±0.01 mm and a high matching degree of pump body assembly. The company has obtained ISO 9001 Quality Management System Certification and CE Product Certification, and implements strict quality control standards.
Super Wear-Resistant Materials, Leading Service Life in the Industry
It selects high-chromium alloys (Cr26-Cr28) and rubber linings produced by top-tier foundries in China, with wear resistance 3 times higher than the industry average. The monthly casting capacity reaches 1,000 tons. After heat treatment, the product hardness can reach above HRC 60, and the service life is extended by 2-5 times.
Agile Delivery, Worry-Free Global Supply
It supports delivery of small-batch orders within 20 days and large-batch orders within 45 days. Cooperating with a number of international logistics companies, it provides diversified distribution solutions, covering services in more than 100 countries. At the same time, it maintains inventory of high-frequency wearing parts to minimize equipment downtime.
Full-Process Quality Control, Worry-Free After-Sales Service
• 100% Factory Inspection: Each pump undergoes 36-hour no-load/load testing, dynamic balance calibration, and 3D scanning inspection, with a product defect rate of less than 0.3%.
• Lifetime Technical Support: It provides model selection and survey, installation guidance, and 24-hour fault response services, and issues after-sales solutions within 48 hours.
Cost Reduction and Efficiency Improvement, Creating Value for Customers
By introducing the MES (Manufacturing Execution System) intelligent production system, the cost is reduced by 15%; by adopting Computational Fluid Dynamics (CFD) to simulate the impeller hydraulic model, the efficiency is improved by 5%-8%.

Application Scenarios
Mining Industry
• Tailings Treatment: Conveying mine tailings (gold ore, iron ore, copper ore, etc.) to tailings ponds or dry storage yards.
• Stope Dredging: Cleaning the sediment mixture formed by water and sediments in open-pit mines.
Dredging Engineering
• River/Lake Dredging: Removing sludge to restore water storage capacity (e.g., governance of the Yellow River and Yangtze River tributaries).
• Port Infrastructure: Land reclamation projects (e.g., land formation during the expansion of coastal ports).
Construction and Municipal Fields
• Foundation Dewatering: Extracting the mud-water mixture in foundation pits (solid-liquid separation is achieved by cyclones).
• Subway Tunnel Drainage: Handling the slurry generated during shield tunneling (corrosion-resistant materials are required).
