Product Overview
The TGEC excavator agitator slurry pump is a hydraulic-powered submersible attachment built to move sand, slurry, sludge, sediment, and other semi-solid materials in dredging, construction, and industrial settings. What sets it apart from standard water pumps is the built-in agitator that breaks up compacted sediment and mixes it with water before pumping, so it can handle high-solids content that would clog a conventional pump. It runs off the excavator's auxiliary hydraulic circuit—powering both the impeller and the agitator—and pins onto the bucket linkage for precise positioning in water, slurry pits, dredging sites, and industrial basins. Common uses include sand extraction, pond and lagoon dredging, dewatering sediment-laden excavations, industrial sludge removal, mining tailings management, and marine dredging.
You'll hear this attachment called a lot of different names—hydraulic dredge pump, hydraulic submersible slurry pump, sand pump attachment, sludge pump, or dredging pump attachment—but they all refer to the same core tool. The excavator-mounted setup provides mobility, reach, and precise positioning without requiring flotation platforms or separate support equipment.

How It Works
The agitator slurry pump draws hydraulic power from the excavator's auxiliary circuit to run a hydraulic motor that drives both the pump impeller and a separate agitator mechanism. The agitator—positioned right at the pump intake—uses rotating blades or augers to break up compacted sediment, sand, or sludge and blend it with surrounding water into a pumpable slurry. Once the agitator preps the material, the impeller pulls that slurry into the pump housing and pushes it out through a discharge hose or pipe to wherever you need it. The excavator's boom and arm let you control the pump's depth and position on the fly, so you can keep the intake right where it needs to be without sucking in air. The hydraulic circuit gives you variable speed control, so you can dial in pump and agitator speed based on how thick or dense the material is.
Application Scenarios
Sand and gravel extraction: Pump sand, gravel and sediment from rivers, lakes, pits and quarries for construction material production.
Pond and lagoon dredging: Remove accumulated sediment and sludge from retention ponds, wastewater lagoons, aquaculture ponds and industrial basins.
Construction site dewatering: Remove slurry and sediment-laden water from excavations, foundation pits and construction sites where conventional pumps clog.
Industrial sludge removal: Handle industrial sludge, tailings and process residues in mining, power generation, chemical processing and manufacturing facilities.
Marine and coastal dredging: Pump sediment in harbors, marinas, waterways and coastal areas for navigation maintenance and land reclamation.
Tailings pond management: Remove and transfer mining tailings and process water in tailings storage facilities and settling ponds.
Emergency flood response: Pump floodwater with high sediment and debris content in emergency response and disaster recovery situations.
Installation & Mounting
The agitator slurry pump mounts to the excavator's bucket linkage using the existing bucket pins or a dedicated bracket, and hooks into the auxiliary hydraulic circuit with high-pressure hoses. Before you mount it, make sure your excavator's auxiliary flow and pressure meet the pump's requirements—too little flow and you won't get enough pumping capacity, too much pressure and you risk damaging the motor. Confirm your pin-to-pin spacing, pin diameter, and coupler type so the bracket fits right. Run the discharge hose from the pump outlet to wherever you're sending the material—make sure the hose is sized for the pump's flow rate and secured so it doesn't whip around during operation. Route the hydraulic hoses with enough slack for full boom and arm movement, and add abrasion protection anywhere the hoses might rub against the excavator or the ground. Depending on the motor configuration, you may also need a case drain line—verify that before you start installation.
Wear Parts & Service
The main wear components on an agitator slurry pump are the impeller, agitator blades, pump housing volute, wear plates, hydraulic motor, seals, and hydraulic hoses. The impeller and agitator blades take the brunt of abrasion from sand, sediment, and abrasive slurry—check them regularly for wear, erosion, or damage. The housing volute and wear plates protect the internal guts from abrasive wear and need replacement once they're worn past the manufacturer's limits. Keep an eye on the hydraulic motor for leaks, odd noises, or loss of performance, and check all seals for any leakage that could let water or slurry into the hydraulic system. Grease all lube points on schedule, and inspect the hydraulic hoses for abrasion, cracking, or leaks. TGEC stocks genuine replacement impellers, agitator blades, wear plates, seals, and hydraulic components for every model in the line.
