• Technology meets performance. In a world shaped by complex technology, pumps and valves perform vital functions. Their smooth and efficient operation is crucial if diverse systems in ­industry and power plant engineering, water and waste water management, building services and mining are to achieve their optimum performance. This demands the kind of top-flight technology expected by KSB’s customers and provided across the globe by highly qualified staff. Their shared mission: to ensure their customers’ success via outstanding products and services. In striving to achieve this vision, KSB continues to develop ground-breaking technical solutions as demonstrated by the three examples in this report.

  • “The ecology of the world’s oceans is under threat due to ballast water from around 60,000 cargo ships. Our cleaning system can help to halt the spread of non-native ­organisms – without the need for chemicals.”

  • Tackling invasive species efficiently

    Ballast water cleaning system

    The limnotherma protonei clam from Asia has populated the west coast of the American continent. With no natural enemies, it has been able to reproduce rapidly and can clog the cooling water intakes of power stations and industrial plants. In the opposite direction, the American warty combed jellyfish has established itself in the Caspian Sea and now competes with native marine species for food. The consequence for local communities: significantly reduced fishing catches. Across the globe, imported invasive species are causing enormous ecological damage to waterways and generating costs running into the billions. The organisms find their way into foreign ecosystems via ballast water which is ­carried by ships to provide stability and balance out loads during voyages before being emptied in ports. In collaboration with the Emden University of Applied Sciences and Kaiserslautern Technical University, KSB has developed an innovative filter and UV system which treats the water without the need for chemicals. Water is filtered as it is taken on board to remove large organisms and particles, while the filter itself is flushed out during the cleaning process by the same water. Thereafter, UV irradiation with an energy-saving low-voltage lamp renders the remaining micro organisms harmless – a 100-percent effective and highly cost-efficient solution which must, however, be capable of functioning in the limited space available on board. With previous testing delivering uniformly positive results, market viability is now being assessed. For ship owners, ballast water cleaning is not merely an ecological problem, but a genuinely existential one. The United States Coast Guard has issued a rule effective within the next few years stipulating that only ships with ballast water management systems will be permitted to enter US waters. Similar ballast water management guidelines have also been proposed by the United Nations International Maritime Organisation. These developments will require around 60,000 ships to be equipped worldwide – a market with real potential.

  • Hydrocyclone for mining applications

    RELIABLE HYDROCYCLONE

    Phosphate rock in the USA, oil sands in Canada or copper ores in Chile: slurry pumps for mining applications handle hundreds of different materials under extreme conditions day by day. To complement its range of slurry transport pumps, KSB’s US American subsidiary GIW Industries Inc. has designed a hydrocyclone which separates mineral particles in a liquid suspension (slurry) by size and density. Comprising a cylindrical section at the top above a conical base, it allows sand and ore to be separated from water and different ores to be separated from each other. The process involves the solids/liquid mixture entering the cyclone via the inlet and circulating in the cylindrical section. Larger particles are thus forced outwards towards the wall and drop to the bottom. The remaining liquid exits the hydrocyclone via the overflow at the top. This energy-efficient mechanical separation combined with the GIW hydrocyclone’s extremely low maintenance requirements offers substantial cost-cutting potential as cyclone outages may cause downtime costs of between 50,000 and 150,000 US dollars. KSB service centres in the world’s most important mining regions provide quick service and ensure trouble-free operation for your systems.

  • “Next-generation fossil-fuelled power plants place much more exacting demands on valves. We intend to provide the technology required in good time.”

  • Ultimate performance for energy and the environment

    High-performance gate valve for new power plants

    By 2020, the amount of greenhouse gases emitted into the atmosphere must have been reduced by at least 20 percent compared with 1990 – this is the target the European Union has set itself. Fossil-fuelled power plants must contribute significantly to this goal. As a result, energy providers and the industry sector have been discussing how to generate more power with lower CO2 emissions under the banner “Power Plants 2020+”. A key part of this endeavour is increasing efficiency by raising boiler pressure and temperatures from the max. 600 °C present in highly efficient power plants today to over 700 °C. This places extreme demands on durability and thus requires innovative technologies and the use of specialised materials. As part of the scope of the “725 HWT GKM”  joint research project, KSB successfully tested newly developed high-performance valves in a major power plant in Mannheim, Germany. Two prototypes of the ZTS high-pressure gate valve were operated at temperatures of up to 725 °C for almost two years; high-pressure globe valves had previously demonstrated their suitability.

    The basic design of these valves developed at KSB’s Pegnitz factory has proven its worth in power plants for decades. With an eye on the challenges of the future, KSB has now optimised the product. The valves are manufactured from a nickel base alloy resistant to high temperatures; a spherical body reduces thermal stresses and elongated yoke arms protect the actuators from the potentially negative effects of the hot steam. The goal of the long-term tests: to establish the permissible operating limits of the valves under these extreme conditions. The findings offer a basis for designing components to be used in future power plants with steam temperatures of over 700 °C – ensuring that technology from KSB makes its contribution to achieving our climate goals.
