Submersible slurry pump
Motor, intake and flanged discharge.
Fleet and production
Dredging, pumping and pipeline equipment.
A working register of the principal units used in dredging, hydraulic fill and reclamation planning.
Equipment register
The main system is in the field.
Submersible dredgers, hopper fleet, booster pumping, HDPE pipeline and support plant are coordinated around the project requirement.
| Group | Equipment | Available unit / role |
|---|---|---|
| Dredgers | 16″ submersible DP400 class dredger | 1 unit |
| Dredgers | 14″ submersible DP200 class dredger | 1 unit |
| Dredgers | 10″ 50HP submersible dredger | 1 unit |
| Dredgers | 8″ 75HP submersible dredger | 1 unit |
| Hopper fleet | Hopper dredgers | 10 units · 100 m³ each |
| Pumping & pipeline | Booster pump station | 1 unit · 350–450 kW |
| Pumping & pipeline | HDPE pipeline | 2 km · 8–16″ |
| Support fleet | Marine & earthworks support | Tugboats, workboats, welding and anchor barges, 20–25 t excavators, D6–D8 bulldozers and vibro-compactors |
Hydraulic fill estimator
Indicative production planning.
Planning basis: combined 160–350 m³/h (DP-200 + DP-50BL + DP-75). Final output requires a source and pipeline test run.
1,280–2,800 m³ per 8-hour shift; 140–400 m typical discharge distance. Longer reaches require project-specific hydraulic modelling.

| System | Discharge | Power / duty | Primary project role |
|---|---|---|---|
| TOYO DP-200-12A | 12 in | 160 kW | Primary heavy-duty sand / hydraulic fill production |
| TOYO DP-50BL | 10 in | Medium duty | Secondary production / fill / stockpile support |
| TOYO DP-75B | 8 in | Medium duty | Supplementary / confined dredging operations |
| Hydra-Tech HT006X8 | 8 in hydraulic | Hydraulic drive | Dewatering / dirty-water / support pumping; not primary abrasive sand dredging |
“Medium duty” is the profile’s duty description; numeric power is not specified for those two systems.
Supporting fleet
Marine and earthworks support.
Tugboats, workboats, welding and anchor barges, 20–25 t excavators, D6–D8 bulldozers and vibro-compactors support the dredging and placement system.
Hydraulic placement
From pipeline to placement.
Discharge arrangements follow the source material, pipeline route and placement area.
Equipment in view
From pump intake to working pontoon.
Intake and agitator
Screen and agitator at the pump intake.
Pontoon mobilisation
Cabin, upright frames and working deck.
Manufacturer references

Perforated intakes and surrounding agitators.
Diesel-driven dredge pump packages
Engine, coupling and centrifugal pump on a skid.
Dredger deck
Suction pipe and lifting assembly.
Deck-mounted pipework and handling gear.
Configuration notes
Production and pumping limits.
Profile planning figures require source verification and a project-specific test run.
View production and pipeline details
Combined planning range only. Final output depends on source quality, dredging depth, distance, elevation and a pipeline test run.
- The 2 km pipeline inventory is not a guaranteed discharge-distance or production rating.
- Booster-assisted longer reaches require project-specific hydraulic modelling before output is committed.
- Recoverable reserves require an approved boundary, bathymetry and subsurface sampling; visible water area alone is not a certified reserve.
- The slide 12 fleet register and slide 14 core-systems table list different sizes and model descriptions. They are retained separately; their exact unit-to-model mapping requires confirmation.

View recommended Hydra-Tech power-unit configuration
The profile recommends this configuration for HT006X8. It is not an installed-unit specification or independently verified OEM rating.
| Parameter | Profile recommendation |
|---|---|
| Engine | 150–180 HP mechanical diesel |
| Hydraulic pump | Variable-displacement axial-piston |
| Maximum hydraulic output | 70 GPM / 265 L/min |
| Working pressure | 170–190 bar / 2,500–2,800 psi |
| Reservoir | 350–400 L, AW46 hydraulic oil |
| Filtration | 10 micron return filtration |
| Cooling | Large hydraulic oil cooler |
| Hoses | 1.5 in pressure/return + case drain |
| Discharge | 8 in hose or HDPE line packages |
- Profile continuous-duty recommendation: 155–180 HP.
- Profile engine options: Deutz BF6L913C / BF6L914C; alternatives Cummins 6BTA / 6CTA and Perkins 1006-6T.
- The profile describes WP10/WP12 as technically possible but oversized for one pump.
- Commission gradually in clean water; confirm pressure, flow, oil temperature and case-drain behaviour before refinery deployment.
Non-flammable service only unless OEM confirmation and refinery HSE approval are obtained. Not a primary abrasive sand-slurry dredging pump.
