Hydraulic & Electric Dredging Slurry Pumps
Review excavator-mounted hydraulic and submersible electric pump configurations for moving sand, silt, sludge and other solid-bearing mixtures. Preliminary selection starts with the required duty point, medium, discharge route and available power source.


Dredging Slurry Pump
Slurry Pump (also known as Dredging Pump) Integrated with Excavator This integrated equipment assembly is an engineered solution designed for efficient handling of sludge, silt, or solid-laden liquids in demanding environments. Below is a technical breakdown of the system:
Equipment Overview
- Slurry Pump: A centrifugal pump specifically engineered for transferring high-concentration, highly abrasive slurries (e.g., mud, ore slurry, tailings). Features wear-resistant construction with components such as high-chrome alloy impellers and rubber linings.
- Excavator Integration: The pump is mounted onto excavators via hydraulic systems or mechanical interfaces, enabling combined excavation and slurry transfer capabilities. This configuration is ideal for mobile operations requiring rapid deployment.
Product Overview:
The hydraulic slurry pumps are new-type slag slurry pumps that draw on advanced foreign technologies. They are equipped with agitators and driven by a hydraulic system. After years of testing and improvement, they have been very maturely applied to various types of excavators. By using their own hydraulic systems, in situations where the silt, sediment, and sand are too thin for excavation and inconvenient for vehicle-mounted transportation, the hydraulic slag slurry pumps can be used to extract and achieve long-distance conveying operations. As an auxiliary device of excavators, it greatly improves work efficiency.
- Main Features:
In addition to the agitator impeller on the pump body, hydraulic agitators and hydraulic augers can also be equipped; free transfer between work sites; high extraction concentration. - Product Specifications:
There are various specifications such as 4 inches, 6 inches, 8 inches, 10 inches, 12 inches, etc., which are suitable for multiple series of excavators of multiple brands such as Caterpillar, Volvo, Komatsu, Sany, etc. - Product Applications:
Widely applied to the desilting projects of inland river channels, the treatment of sediment in ports, the sand pumping in tailing ponds, ore dressing, etc.
Hydraulic Dredging Slurry Pump Selection:
- Determine the required head, flow rate, conveying distance, etc. according to the actual working conditions of the user.
- Consult the parameters of the excavator and clarify the parameters such as the displacement and pressure of the excavator’s hydraulic system.
- Select the model of the hydraulic motor accordingly.
- Calculate the actual output power of the excavator’s hydraulic system and select a suitable pump to be equipped.
Product Overview:
The Electric Slurry Pumps feature high efficiency, strong abrasion resistance, built-in stirring function, and a novel structural design. They are ideal equipment for tasks such as pumping slurry, river dredging, sand regulation and control, and transporting tailings
- Working Principle;
The Electric slurry pumps are equipped with stirring impellers. The motor drives the impellers and the stirring impellers to rotate at a high speed, which stirs and mixes the precipitated slurry, mud and other media evenly. Thus, it enables the transportation of high-concentration media without the need for auxiliary devices. Main materials CR26 high wear-resistant alloy, 304stainless steel, 316L stainless steel, etc., and customization is available. - Product Applications:
Widely used in river dredging and sand regulation, extraction of high-temperature slurry in power, thermal energy and other industries, cleaning of tailings, extraction of sand and sediment in bridge and pile foundation projects, and transportation of slurries containing abrasive solid particles in chemical engineering, environmental protection and other industries.
Electric Dredging Slurry Pump Selection:
- Determine the required head, flow rate, conveying distance, etc. according to theactual working conditions of the user.
- Confirm power supply parameters(50HZ/60HZ/220V/380V/415V/660V/1140V).
