KSB’s dredging solutions cater to the complex requirements of the dredge industry.

GIW® pumps deliver dredging solutions that boost productivity and profits. GIW® dredge pumps are designed to handle the complex and variable challenges of dredging worldwide.

The complexities of dredging demand a reliable, global source of dredge pump technology

From clearing waterways for the safe passage of ships to land reclamation, to beach nourishment, dredging is a necessary ongoing response to natural processes, and is vital for the economy and the environment. Land reclamation and remediation projects rely on dredge operators to restore lands to productive use. Dredging takes place under extremely complex and variable conditions around the world. Dredging contractors require a reliable and innovative global partner that can provide dredge pumps and parts for a broad range of applications worldwide.

KSB offers high-performance GIW® dredge pumps for the entire spectrum of dredging needs. Our dredge pump technology is used in capital dredging, maintenance dredging, and environmental dredging projects. As a global supplier with a strategic network of international partners, KSB is not only a reliable local source of high-quality dredge pump components but also an experienced partner for large-scale international dredge projects. KSB provides complete pumps for new building projects, and on-site services.

The GIW® pump range includes inboard pumps, underwater dredge pumps, single and double walled pumps, heavy-duty and severe-duty slurry pumps and other process pumps for every task. KSB can provide GIW® pumps in various configurations—underwater pumps mounted on the suction pipe, inboard pumps and booster stations. Thanks to advanced engineering techniques and our comprehensive R&D approach, we can offer a new generation of dredge pumps for a broad range of applications. On-going improvements to hydraulic design, advanced wear technology, and proprietary materials enable us to develop superior quality products tailored to your specific needs.

Dredging in Rivers, Lakes and Tailings Ponds

Rivers, lakes and tailings ponds require regular sediment removal, which takes a toll on dredge equipment. Rugged GIW® pumps keep your operations running for the long haul.

Dredging is vital to the navigability of rivers and lakes, and the operation of tailings storage facilities in mining. Dredge pumps are also used to harvest sand and gravel used in construction and various other applications. Dredging equipment used in these variable settings face several challenges. Dredge pumps need to be powerful enough to extract high concentration slurries from depths of 10-15 m. Since they are called on to handle abrasives such as sand, silt or gravel, along with muck and debris, the wear life of these pumps is limited. Durable and efficient dredging pump solutions help reduce both scheduled and unscheduled downtimes, lower operating costs and improve overall productivity.

KSB’s line of GIW® slurry pump supplies a wide range of dredging solutions for rivers, lakes and other intra-coastal waterways. The excellent suction characteristics of GIW® pumps are ideal for inland dredging applications including the deepening of lakes, widening of waterways and maintenance dredging. KSB also provides products for all aspects of tailings management, from tailings pumping to tailings transport systems as well as solutions for pumping reclaimed water and land reclamation. GIW® dredge pumps offer long wear life and consume less energy and fuel.

As a leading supplier to the global dredge industry, we supply durable, cost-effective solutions that improve the productivity and sustainability of your dredging processes. KSB’s rigorous materials testing, custom-engineered concepts, and robust mechanical designs improve efficiency, extend wear life and increases reliability. Our pumps are always designed with your processes in mind.

Ocean-going Dredge

GIW® slurry pumps provide long-lasting performance for offshore dredging projects. KSB provides hard-wearing dredge pumps for the dredging industry.

Offshore dredging is a complex and challenging field. Dredges need to extract high-concentration slurries from depths of 10 to 100 m and transport them over a distance of up to 6 km. These pumping systems are equipped to handle materials such as large rocks, sand, fine sediments and debris while ensuring continuous operation. High-performance dredge pumps also have to withstand wear and tear to avoid costly downtimes and ensure productivity. Selecting the right pumping systems for demanding offshore projects requires analysis to define the best parameters for pump selection, performance and wear materials.

KSB is a complete dredge pump provider for a wide variety of offshore dredge applications, from ocean dredging to channel deepening and capital dredging. GIW® underwater dredge pumps and inboard pumps are integral components in cutter suction dredges, trailing suction hopper dredges, booster stations, barges and other dredging vessels. GIW pumps are designed to have high efficiency over a wide range of flow rates. This ensures the best use of available power – for greater energy efficiency and lower fuel consumption. Our pumps offer a low cost per cubic metre of soil moved. GIW® pumps also feature excellent hydraulic performance, robust mechanical designs and industry-leading materials on critical wear components such as pump casings, impellers and liners. Choose our hard-wearing dredging pump solutions to lower your operating costs, increase efficiency and minimize downtimes.

Based on our experience as a market leader of heavy-duty centrifugal slurry pumps, KSB is in a unique position to provide not only superior pumping technology through our custom-engineered solutions, but also extensive project experience on a global scale. Given the complexity of ocean-going dredge applications, having an experienced partner at your side is an absolute must. KSB has collaborated with international partners to realize several large-scale dredging new building and retrofit projects. Our successful portfolio of projects and solutions speaks for itself. We continuously strive to improve our products through our in-house R&D, including full-scale lab tests for hydraulic performance and extensive materials testing and development.
