An excavator sand suction pump (also called a dredging pump attachment or submersible slurry pump) mounts on—or is suspended from—the boom of a hydraulic excavator. Driven by the carrier’s auxiliary hydraulics, it vacuums sand, silt, gravel, and slurry and discharges the mixture through a hose to a spoil area, barge, or geotube. It lets a single excavator dig, suck, and move material in one continuous operation—perfect for shallow‑water, shoreline, and pit‑clean‑out projects where conventional dredgers can’t reach.
Plug‑On Versatility – Fits the same hitch used for buckets; swap in < 5 minutes.
Alloy Wear Parts – Hi‑Cr volute and impeller extend service life 3× over cast‑iron.
Built‑In Agitator – Side cutters fluidize compact clay so the pump never starves.
Low Cavitation Risk – Wide vane passages maintain pressure even at 30 % slurry.
Remote Depth Control – Excavator boom reaches 14 m deep without cofferdams.
Minimal Footprint – No pontoons; perfect for urban canals and narrow rivers.
Field data shows users recover investment in an excavator sand suction pump within six months compared with renting a dedicated cutter‑suction dredger.
The Working Principle of an Excavator Sand Suction Pump
The YG excavator sand suction pump operates on a straightforward yet effective principle, leveraging the power of your excavator’s hydraulic system:
Submersible Pump Head: The pump head, designed for submerged operation, is equipped with a powerful impeller and a suction inlet.
Hydraulic Drive: The excavator’s hydraulic system powers the pump motor, driving the impeller at high speeds.
Suction Action: As the impeller rotates, it creates a low-pressure zone at the suction inlet, drawing in water and suspended solids (sand, silt, slurry).
Discharge: The rotating impeller then propels the mixture of water and solids through the discharge hose to the desired location.
Agitation (Optional): Some models feature an integrated agitator or cutter head to loosen compacted sediments, enhancing the pump’s suction efficiency, particularly when dealing with densely packed materials.
YG Machinery offers a robust and efficient excavator sand suction pump designed to transform your excavator into a powerful dredging and material transfer machine. This versatile attachment allows for the easy and cost-effective removal of sand, silt, slurry, and other sediments from various water bodies and confined spaces. Engineered for durability and high performance, our excavator sand suction pump provides a practical solution for a wide range of dredging and material handling applications, eliminating the need for dedicated dredging vessels in many situations.
