A vaccine against clogging: the new wastewater pumps from KSB

The issue is that these items obviously do not disintegrate in water, but form a stringy mass of solids which can cause clogging in wastewater pumps. This results in malfunctions that jeopardize the economic efficiency and reliability of plant operation. Yet the challenges facing pump development for wastewater engineering go far beyond this. Because alongside the goals of achieving improved operational reliability and offering non-clogging pumps, energy efficiency also plays a decisive role.

Squaring this circle has long been KSB’s goal – by offering wastewater pumps that work reliably with all types of contaminants (for example sand) and prevent clogging while delivering energy-efficient operation and minimizing operating costs. For KSB, realizing this ambition even more fully means taking wastewater engineering to the next level – with the development of optimized hydraulic systems and motors for waste water pumps including the submersible pumps Amarex and Amarex KRT. KSB’s revised impeller designs in particular mark a major step forward. This new generation of impellers boosts hydraulic efficiency to previously unattainable levels and – thanks to a special design – prevents insoluble paper towels in the wastewater from causing blockages or larger objects from clogging the pump. In addition, a wide range of designs, sizes and materials including cast iron and stainless steel ensure that these wastewater pumps can be perfectly adapted to all applications in the field of wastewater pumping and wastewater treatment – whether for municipal drainage, industrial wastewater treatment or handling highly abrasive and corrosive fluids. KSB has also made further improvements to its motors: They now meet the latest standards for high-efficiency motors in efficiency class IE3 and are characterized by particularly long service lives.

If pumps cannot clog, then they cannot cause malfunctions requiring costly maintenance. But this is not the only advantage of KSB’s new wastewater pumps - they are also environmentally friendly and easy to repair. For example, straightforward recycling is available for all components, and non-toxic oils are used to ensure critical seal lubrication for the submersible pumps. In addition, the spare parts for certain models have been designed such that they can be used for all pump sizes. And in these times of crisis it goes without saying that KSB SupremeServ continues to offer its full range of services to wastewater treatment plants and other operators in need of repairs – worldwide.

We may not always notice them – but infrastructural processes such as wastewater treatment are essential in keeping our systems running. Ground-breaking wastewater engineering from KSB helps to make them safer, more reliable and more resilient – even in exceptional circumstances.
