Product Description
Excavator driven hydraulic submersible sand dredging slurry pump
Our pump is mainly used as an accessory device of excavator, in the case of more water, silt, sand,
mortar is less conducive to excavating and inconvenient vehicle transport, extraction operation, greatly improving the work efficiency. It is widely used in dredging engineering of the inner channel, harbor sediment control, tailings pond sand extraction, ore dressing, municipal sewer silt discharge, and so on.
The hydraulic Hank suction pump adopts special high chromium alloy for slag, and the motor selects special
quantitative plunger motor for the dredging industry, which has the characteristics of advanced structure, reasonable
performance, high efficiency, and stable work.

- Heavy-duty, reliable, and robust dredge body design and construction.
- Specially designed dredger pump, suction reamer head, and motor to realize high dredger suction ratio and more thorough dredging.
- Best wear-resisting.Good wear-resisting property and big flow passageway make the dredger pump suitable for mud, sand, big solid particles, ore pulp, coal pulp, and coarse sand dredging.
- Triple protection. Flexible sensors to realize over-heating protection, water-intake inspect protection, and oil chamber protection to ensure long and safe pump operation under abominable working conditions.
- Especially for multifunctional small and medium scale dredging projects
- High-chromium alloy material, aluminum alloy, stainless steel pump material are available for different worksite situations.
- One pump could add 3 pieces of extra agitator for higher work efficiency.
- Hydraulic system pump available.
