Product Description
Sand dredge slurry pumps are horizontal, single-stage, and double-casing pumps designed with innovative hydraulic performance. The over-flow components are manufactured from high-chromium alloy to ensure maximum abrasion resistance. These units are engineered for high efficiency, energy savings, and reliable operation in harsh environments.
The equipment can effectively convey gravel, slurry, or sand with solid-to-liquid densities of up to 60%. It is ideal for transporting strong erosion slurry, slag, or grout containing solid particles. Common applications include sand pumping, land reclamation, and managing tailings in metallurgical industries.
Application Scenarios
The double-pump case structure is extensively used for extracting medium particles such as mud, fine sand, and tailing slag for long-distance transport. It is highly suitable for:
✓
Marine suction and sand extraction
✓
Land reclamation and dock construction
✓
River dredging and sludge treatment
✓
Power plant ash and metallurgical tailings transport
Successful Projects
In one notable project, a customer required a powerful high-head relay pump to transport solids from a lake dredger over a distance of 1600m. The DS300-70 model was selected for its high efficiency and wear-resistant double-shell structure.

Frequently Asked Questions
What materials are used for the pump's wear parts?
The over-flow components are made of high-chromium abrasion-resistant alloy, designed specifically to handle high-density slurries and gravel.
What is the maximum discharge distance for these pumps?
Depending on the model and system configuration, these pumps can support a discharge distance of up to 2000 meters.
Can the pump handle saltwater conditions?
Yes, with special anti-corrosion treatments, the pump is suitable for seawater ash, marine sand extraction, and salt spray environments.
What are the available drive options?
The pumps can be driven by either diesel engines (4-1066HP) or electric motors, depending on the site requirements.
Is it possible to connect multiple pumps in a series?
Yes, within the allowable pressure range, these pumps can be used in multiple-stage series connections with a maximum working pressure of 3.6Mpa.
What is the maximum particle size the pump can pass?
The pump is designed to handle gravel and solids with a diameter of approximately 50mm.
