KSB’s Amarex submersible pumps are supplied with free-flow impellers and are designed for transferring all types of wastewater and sewage containing long fibres and solid substances, including stormwater transport, recirculation and sludge treatment. The beauty of these new Amarex submersible wastewater pumps is that they have significant efficiency improvements. These electric submersible pumps by KSB have an overall efficiency of up to 69%, due to the new optimised hydraulic system and IE3 electric motor, resulting in a significant reduction in energy costs and increase efficiency.
