Excavator Dredge Pumps by TGEC

TGEC designs and builds excavator dredge pumps for sand extraction, sludge removal, sediment dredging, and marine material handling. Our lineup centers on hydraulic agitator slurry pumps with integrated mixing impellers that keep solids suspended for pumping high-density slurry through a discharge hose. With twelve models spanning 8 to 36 ton excavators, flow rates from 80 to 500 m³/h, and discharge heads up to 35 m, the range covers a broad set of dredging and sediment-removal applications. As a factory-direct manufacturer, we supply these attachments to equipment dealers, dredging contractors, marine construction firms, and qualified OEM partners with sourcing and technical support.

Application Scenarios

Pond and lake dredging: Remove accumulated sediment, sludge and organic material from retention ponds, lakes and aquaculture facilities.
Sand and gravel pumping: Extract and transport sand, gravel and sediment from riverbeds, quarries and mining operations.
Harbor and marina maintenance: Dredge navigation channels, boat basins and marina slips to maintain required water depths.
Underwater construction excavation: Remove slurry and sediment from foundation pits, cofferdams and construction excavations below water level.
Sludge and sediment handling: Pump thickened sludge and settled sediment from lagoons, tanks and settling ponds.

Machine Compatibility

TGEC excavator dredge pumps cover machines from 8 up to 36 tons across twelve models. Final fit depends on the specific model, your excavator's operating weight, auxiliary hydraulic flow and pressure, pin spacing, pin diameter, and coupler type. Each model has defined hydraulic power requirements that need to line up with your machine's auxiliary circuit capacity.

OEM & Bulk Supply

As a direct manufacturer, TGEC supplies excavator dredge pumps to equipment dealers, dredging contractors, marine construction firms, and OEM partners around the globe. We offer dealer and bulk-supply programs based on model selection, order volume, machine specs, and project needs. OEM and private-label arrangements can also be explored based on partner requirements and production feasibility.

Frequently Asked Questions

What is an excavator dredge pump used for?+

An excavator dredge pump is a hydraulic attachment mounted on an excavator to remove sand, sludge, sediment, and other solids from water. It is commonly used for pond and lake dredging, sand and gravel extraction, harbor and marina maintenance, and sediment removal from underwater construction sites. Unlike electric submersible pumps, it is driven by the excavator's auxiliary hydraulic circuit, which makes it suitable for mobile and remote dredging operations.

How does an excavator agitator slurry pump work?+

An agitator slurry pump uses a hydraulic motor to drive a submerged pump unit with an integrated mixing impeller. The agitator breaks up and suspends settled solids, while the impeller moves the resulting slurry through a discharge hose. This design allows the pump to handle material with higher solid content than a standard water pump. Actual performance depends on particle size, concentration, slurry characteristics, hose diameter, and operating conditions.

How do I choose the right dredge pump for my excavator?+

Start with your excavator's operating weight and auxiliary hydraulic flow and pressure, since these determine which pump models your machine can drive. Then consider the material you are pumping — sand, silt, sludge, or gravel — the required flow rate and discharge head, and the depth and distance of your discharge line. Matching the pump to your hydraulic circuit capacity is more important than selecting the largest model. If you are unsure, send us your machine specs and project details for a recommendation.

What excavator specifications are needed for pump matching?+

To match a dredge pump to your excavator, we need the following: operating weight, auxiliary hydraulic flow (L/min or GPM) and pressure (bar or PSI), pin spacing and pin diameter of the stick, coupler type (manual or hydraulic quick coupler, or direct pin-on), and the excavator make and model. These specifications confirm both hydraulic compatibility and mechanical mounting fit. Final fit is always verified against the specific pump model and your machine's mounting interface.

Can TGEC provide custom mounting and OEM dredge pump solutions?+

Yes. TGEC can review custom mounting configurations based on your excavator model and mounting dimensions, including bracket and interface adaptation where required. For dealer and OEM partners, we offer bulk-supply programs and private-label arrangements subject to production feasibility and order volume. Contact us with your machine list and project requirements to review available options.
