Zidong hydraulic submersible dredge pumps are engineered for excavators ranging from 120 to 360 series, providing efficient solutions for challenging excavation environments with high water content, watery sludge, and sand conditions.

By replacing the standard bucket with our hydraulic mortar pump system, operators achieve high-density extraction with significantly improved efficiency. The system enables long-distance material transportation and can be equipped with a dedicated hydraulic station for operation in harsh environments where electricity is unavailable.

• Integrated bottom mixing device with optional bilateral/multilateral agitators prevents clogging and ensures thorough solid-liquid mixing
• Handles solid materials up to 50mm maximum particle size with extraction concentration reaching 70% or higher
• Powered by excavator hydraulic system or diesel engine for remote area operation without electricity requirements
• Wetted components including pump casing, impeller, guard, and mixing impeller constructed from high-chrome alloy for maximum durability
• Unique sealing mechanism reduces maintenance frequency and enhances operational efficiency

• River, lake, and port dredging and desalination projects
• Sand and gravel extraction for harbor reclamation and construction
• Handling iron tailings, slag, and other industrial waste materials
• Forge slag, sludge, and industrial byproduct removal
• Sand pumping and gold mining operations
