Tampa Diver-Operated Dredge Pump
The Tampa Diver-Operated Dredge Pump is a fully submersible underwater dredging system built for precise sediment, sludge, sand, and slurry removal below the waterline. Built around the Tampa Series electric submersible slurry pump platform, this system gives dive teams direct control at the suction point for work zones that are difficult to reach with larger dredging equipment.
The Tampa diver-operated dredge is best suited for controlled underwater cleanup, structure maintenance, marina work, industrial basins, wastewater lagoons, shallow-water sediment removal, and other projects where precise underwater solids removal matters more than maximum production volume.

Performance and Solids Handling
The Tampa Diver-Operated Dredge Pump is designed for controlled underwater solids removal, not high-volume production dredging. The system uses a centrifugal submersible slurry pump platform and should be sized around the material, solids concentration, hose layout, total dynamic head, pumping distance and diver operating conditions.
This system can support up to 30% solids by weight when properly selected for the application. Actual production depends on the selected Tampa pump model, material type, particle size, hose diameter, suction conditions, discharge distance, pump curve, and site setup.
Higher-flow Tampa pumps can support larger hose setups, and longer pumping distances, but diver-operated dredging should still be positioned as a controlled underwater removal system. Final expected production should be confirmed by DAE Pumps before quoting.
Tampa Pump Options for Diver-Operated Dredging
The Tampa Diver-Operated Dredge Pump can be configured with select Tampa Series submersible slurry pump models based on the number of divers, material type, solids size, flow requirement, hose layout, discharge distance, power source and site conditions.
Smaller Tampa models are typically used for controlled, lower-flow diver-operated dredging. Larger Tampa models, including the Tampa 4110, can be used when the job requires more flow capacity and the system is properly sized for diver operation. Larger configurations should be reviewed with DAE Pumps to confirm pump curve, hose sizing, and power requirements.

Industrial Applications
The Tampa Diver-Operated Dredge Pump is used where solids need to be removed below the waterline with precision and direct control at the suction point. Common applications include:
Marine Infrastructure
Controlled underwater cleanup around docks, pilings, bridge footings, seawalls, and other marine structures where larger dredging equipment can’t reach.
Ports and Harbors
Targeted sediment removal for harbor maintenance, marinas, slips, and shallow channels that require diver access.
Wastewater and Sludge
Cleanout of lagoons, basins, clarifiers, tanks, and other sludge or settled-solids areas where controlled removal matters.
Mining and Process Ponds
Removal of abrasive slurry and sediment from process ponds, tailings areas, and remote cleanup zones.
Industrial Water Maintenance
Maintenance dredging around intake structures, cooling-water systems, and plant water infrastructure.
Remediation and Specialty Cleanup
A fit for remediation and other solids-handling projects that require precise, diver-controlled underwater cleanup.

Frequently Asked Questions
Is the diver-operated system electric?
Yes. The Tampa Diver-Operated Dredge Pump is offered in an electric configuration. The right setup depends on site power availability, mobility requirements, hose layout, and overall deployment conditions.
Does a higher-GPM pump mean higher diver-operated production?
Not automatically. Diver-operated production depends on material, solids concentration, suction conditions, hose layout, pumping distance, total dynamic head, and diver control. Larger Tampa pumps may support more flow, but final expected production should be reviewed with DAE Pumps before quoting.
How much solids can the diver-operated dredge pump handle?
The Tampa Diver-Operated Dredge Pump can support up to 30% solids by weight when properly selected and configured. Actual performance depends on the selected pump model, particle size, hose layout, distance and operating conditions.
What information does DAE Pumps need to size the pump system?
To recommend the right pump, power unit, and configuration, DAE Pumps needs a few project details that affect flow, head, and solids handling: the material type, solids concentration, and max particle size; water depth, hose lengths, total pumping distance, and discharge elevation; and your desired production range. Share these with our engineers and we’ll size a system for your site.
Which diver-operated dredge pumps does DAE Pumps offer?
The Tampa diver-operated line includes the Tampa 337, 355, 437, 455, and 4110, covering most diver-operated dredging applications. Need a larger or specialized configuration? Talk to an engineer, and we’ll develop the right solution.
