WN Dredging Pumps
Powering Productivity in the Most Demanding Dredging Environments
First Pump® WN Series Dredging Pumps are engineered to tackle the toughest dredging challenges, from harbor construction to riverbed deepening. Combining robust design, unmatched wear resistance, and effortless maintenance, these pumps deliver high-efficiency performance in transporting abrasive slurries, gravel, and high-plastic clays. Built for reliability in marine, river, and industrial applications, the WN series sets the standard for durability and operational flexibility.
Core Features & Advantages
Unrivaled Wear Resistance:
Critical wear components (impeller, sleeve, guard plates) crafted from KmTBCr27 alloy or advanced A31 material (hardness up to 70HRC), ensuring extended service life even under extreme abrasion.
Dual-pump shell design (600WN to 1000WN models) enhances safety and reliability, allowing continuous operation even if liners wear thin.
Effortless Maintenance:
Front-disassembly structure and specialized tools enable quick access to internal components, minimizing downtime.
Impeller secured via four-start trapezoidal thread for robust torque transmission and easy removal using the integrated disassembly ring.
Electric turning mechanism (700WN to 1000WN) simplifies impeller maintenance with automated forward/reverse rotation.
Superior Hydraulic Performance:
Advanced CFD-optimized design ensures high efficiency (2 to 3% above industry averages), low power consumption, and exceptional NPSH for strong suction (up to 20m+ digging depth).
Wide impeller flow channels prevent clogging, enabling smooth transport of gravel, sand, and high-viscosity clays.
Adaptable & Versatile:
Adjust performance by altering impeller speed or diameter to match varying flow and head requirements.
Multiple shaft seal options: mechanical seal, packing seal, or hybrid systems (200WN to 500WN); spiral sleeve L-shaped rubber seals (600WN to 1000WN) ensure zero leakage.
Robust Construction:
Single-stage, single-suction cantilever horizontal design reduces weight while maintaining structural integrity.
Gearbox-integrated models eliminate separate bearings/frames, saving space, cost, and failure risks.
Technical Specifications
Size Range: 200mm to 1200mm (8" to 48")
Flow Rate: Up to 25,000 m³/hr
Head / Pressure: Heads to 263ft (80m) / Pressures to 1,095 psi (7,555kPa)
Max Particle Size: Handles gravel and solids with ease
Materials: High-chrome alloys (KmTBCr27, A31), hardened to 58–70HRC
Applications
Marine & Port Development: Harbor construction, channel deepening, and coastal reclamation.
River & Lake Dredging: Sediment removal, flood prevention, and environmental restoration.
Industrial Slurry Transport: Sand suction, hydraulic filling, and mining tailings.
Offshore Operations: Compatible with cutter suction dredgers and trailing hopper dredgers.
Why Choose WN Dredging Pumps?
Cost Efficiency: Long-lasting wear parts and reduced maintenance lower total ownership costs.
Reliability: Proven in extreme conditions, with vibration-free operation and low noise levels.
Flexibility: Customizable configurations (grease/thin oil lubrication, gearbox integration) suit diverse project needs.
Sustainability: High efficiency reduces fuel consumption and environmental impact.
