Overview
Portable cutter-suction dredge PD-1220 is a compact, transportable dredging unit designed for narrow waterways, sedimentation tanks and small-scale dredging projects. The unit integrates cutterhead abrasion, suction transport and electric drive for quick deployment without large vessels. It is optimized for municipal maintenance, industrial tank cleaning and agricultural pond management.

Core Features
The system comprises a power unit, cutter-suction assembly and control module. Spiral cutters fragment sludge while mud pumps convey the slurry ashore. Constructed from corrosion-resistant stainless steel, the unit is rated for operations down to 20–30 m underwater. Optional camera and remote-control modules provide real-time monitoring and parameter adjustment to reduce blockages.

Core Advantages

• Portability: Modular build for single-person handling and access in narrow channels.
• Adjustable cutting and flow: Flow regulation and interchangeable cutters for varying sludge hardness.
• Anti-blockage capability: Integrated backwash valve and automatic clearing routine.
• Effective transport: Typical slurry concentration 30–40%, suitable for most small projects.

Application Fields

• Municipal: Small river and sluice maintenance, stormwater channel clearing.
• Industrial: Sedimentation tank dredging, wastewater pond cleaning, tailings pond management.
• Agricultural: Fishpond dredging, irrigation channel maintenance, paddy ditch cleaning.
• Ecological: Landscape lake and constructed wetland maintenance, reservoir tributary upkeep.
• Mining: Small sump dredging, mineral slurry tank cleaning.

Success Cases (illustrative)
Example: A Rotterdam narrow-river project completed 500 m in 3 days using the portable unit, improving throughput versus manual methods. Example: A US factory combined the unit with tank-cleaning equipment to restore drainage and reduce downtime.

Environmental & Compliance
Electric drive design eliminates fuel emissions on site. Slurry concentration control limits turbidity and optional eco-cutters with covers reduce leakage in sensitive waters. The product is CE certified and adapted for export markets.

Maintenance & Support Guidance

• Daily: Flush hoses and inspect cutter wear after each use.
• Replacement: Replace cutters when blade wear exceeds 3 mm.
• Calibration: Check and calibrate flow-regulation valves quarterly.
