Step 1 of 6
Mount the pump on the excavator
Most hydraulic submersible pumps work from an excavator boom. Decide early how it hangs.
A flexible mount hangs the pump from lifting lugs with a chain spread. It is quick to rig and forgiving on the boom, but gives less control over the suction position.
A fixed mount bolts the pump to the boom or stick through an adapter bracket. It gives precise, pushing control for hard or compacted material and is the usual choice when cutting or levelling.
Check the excavator's reach, lifting capacity at full outreach and the combined weight of pump, head, hoses and water-filled pipe.
Site checklist
Wear & spare-parts planning
What wears first — and what to keep on site
In abrasive duty, start by monitoring the slurry-contact wet end. There is no universal fastest-wearing part or replacement interval: sediment, materials, speed, operating point and inspection history determine the priority.
- Wet-end parts · abrasion priority
Impeller, wear plates, liners / throat bush and casing
Sand and sharp mineral particles erode slurry-contact surfaces. Gravel can add impact damage. Falling flow or head, increasing clearances and wall thinning warrant inspection.
- Seals · leak prevention
Shaft seals, O-rings and joint gaskets
These are service spares, not necessarily the fastest-wearing parts. Leakage or water ingress needs diagnosis; follow the sealing arrangement and lubricant instructions for the chosen model.
- Hoses & bends · exposed sections
Discharge hose, elbows, hydraulic hoses and coupling seals
Slurry abrades discharge sections, particularly bends. Hydraulic hoses wear through rubbing, flexing or ageing, not contact with dredged soil. Inspect protection, joints and ratings.
- Head accessories · only when fitted
Jet nozzles and cutter / agitator tips
Jets need checks for erosion and blockage. Cutting tips can wear in compacted or abrasive sediment. Order only accessories that match the selected head.
Set spare quantities from observed wear, delivery lead time and outage risk. Measure clearances and wall thickness against the supplier's limits; never inspect moving or pressurised equipment. Isolate and depressurise before maintenance.
Final step
Pick your complete setup and request an RFQ
Select everything your operation needs. One request covers it all — no sign-in needed.
Start with a complete package · compatibility checked before quoting
Or pick parts yourself below — changing any item turns the package into a custom setup. We check compatibility of every component before quoting.
Submersible dredge pump · pick one
Suction head · pick one
Mounting · pick one
Power · pick one
Lines, pipe & extras · pick any
Downtime protection
Add a wear-parts reserve to the same RFQ
Wet-end parts are the abrasion priority. Actual wear depends on mineral hardness, solids concentration, pump speed and operating point — even fine silt can be abrasive. No fixed replacement hours are assumed.
Silt & mud essentials
Seal and hose readiness; add wet-end spares if sand is present.
Abrasive sand reserve
Adds impeller and renewable wet-end wear surfaces.
Gravel & remote-job reserve
Adds casing assessment for abrasion and impact exposure.
Packages add to your system without clearing your choices. Jet nozzles and cutter tips are included only when that equipment is selected. Supplier confirms quantities, exact pump model, wear materials, dimensions and connections; these are not verified catalogue matches.
