Dredge Pumps & Wear-Resistant Pump Parts
HANSEL supplies dredge pumps, pump configurations and wear-resistant pump parts for cutter suction dredgers, trailing suction hopper dredgers, booster stations and dredging pipeline systems.
Designed for transporting mud, sand, gravel and abrasive slurry, our dredge pumps and replacement components help improve dredging efficiency, reliability and service life in demanding operating conditions.
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.
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.

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.
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.
