Overview

The Core Component of a Dredging System

The dredging pump is one of the core components of a dredger. Its hydraulic performance directly affects the production capacity, discharge distance, energy efficiency and overall working performance of the dredging system.

Through cooperation with technical institutes and manufacturers, HANSEL has developed and supplied a series of mud pumps optimized for dredging conditions. These pumps are designed with high-efficiency hydraulic curves, reliable performance and stable operation for transporting abrasive slurry mixtures.

HANSEL dredge pumps can be used on cutter suction dredgers, trailing suction hopper dredgers and booster stations for transferring mixtures of water, mud, sand, gravel and other solid materials.

  • High-efficiency slurry transportation
  • Optimized hydraulic pump configuration
  • Reliable performance for dredging conditions
  • Suitable for dredgers and booster stations
  • Wear-resistant wet-end components
  • Custom pump and parts supply available

Pump Configuration

Dredge Pump Models for Different Project Requirements

Different dredging projects require different pump configurations. Pump selection depends on shaft power, inlet and outlet diameter, operating speed, water flow range and maximum solids size.

The following data is provided for preliminary model selection. Final pump selection should be confirmed according to slurry density, particle size, pipeline length, discharge distance, working head and project conditions.

Model Max. Shaft Power (Water) Inlet / Outlet Inner Dia. RPM Discharging Output (Water) Max. Solids Size
10/8F-G 200 kW 250 mm / 200 mm 500–1000 360–750 m³/h 178 mm
10/8S-GH 332 kW 250 mm / 200 mm 600–950 430–1150 m³/h 180 mm
12/10G-G 274 kW 300 mm / 250 mm 400–850 500–1000 m³/h 220 mm
12/10G-GH 440 kW 300 mm / 250 mm 450–700 720–1450 m³/h 210 mm
14/12G/T-G 421 kW 350 mm / 300 mm 400–700 720–1620 m³/h 241 mm
16/14TU-GH 555 kW 400 mm / 350 mm 300–500 1100–2200 m³/h 230 mm
WN300 533 kW 420 mm / 300 mm 450–550 1600–2200 m³/h 241 mm
WN350 584 kW 450 mm / 350 mm 450–560 2000–2900 m³/h 200 mm
WS400 805 kW 500 mm / 400 mm 400–500 2600–3500 m³/h 240 mm
WN450 960 kW 600 mm / 450 mm 400–500 2800–4000 m³/h 125 mm
WS450 930 kW 520 mm / 450 mm 400–505 2800–4000 m³/h 220 mm
WN500 1400 kW 650 mm / 500 mm 350–450 3500–5000 m³/h 150 mm
WS500 1243 kW 600 mm / 500 mm 420–470 3600–5500 m³/h 220 mm

The above discharging output is based on water performance. Actual slurry output may vary according to slurry concentration, material density, particle size, pipeline resistance and operating conditions.

Engineering Support

Configured for Your Dredging Conditions

Selecting a dredge pump only by pipe diameter or nominal flow rate may lead to low efficiency, excessive wear or unstable performance. HANSEL can assist customers with pump model selection according to real operating conditions.

Information Required for Selection

  • Required flow rate
  • Required discharge distance
  • Pipeline diameter
  • Total working head
  • Material type
  • Maximum particle size
  • Slurry concentration
  • Available engine or motor power
  • Installation position
  • Operating speed requirements

Parts Supply

Wear-Resistant Dredge Pump Parts & Fittings

HANSEL can provide dredge pump parts and fittings for dredging contractors, equipment owners and trading companies worldwide. We can also provide on-site measurement services and supply replacement components with the same material and performance as required.

The recommended material for main dredge pump components is KmTBCr27 wear-resistant alloy, with hardness of 58–62HRC, offering excellent performance under abrasive and erosive working conditions.

Wear-Resistant Materials

Built for Abrasive Dredging Conditions

Dredging pumps often work in harsh environments where mud, sand, gravel and other solid particles continuously pass through the pump body. To improve durability and reduce maintenance frequency, key pump parts must be made from suitable wear-resistant materials.

HANSEL can supply main pump components made from KmTBCr27 wear-resistant alloy with 58–62HRC hardness, providing strong resistance to abrasion and erosion in demanding dredging applications.

  • Improved wear resistance
  • Longer service life
  • Better performance under erosive conditions
  • Reduced replacement frequency
  • Suitable for sand, mud and gravel slurry
  • Custom materials available upon request
