The Amarex submersible motor pumps are designed for handling all types of waste water in municipal, industrial and commercial applications up to a maximum flow rate of 155 m³/h and a maximum head of 47 m. In developing the model, KSB designers have concentrated on low energy consumption and particularly low life cycle costs. This aim has been achieved thanks to two bi-rotational mechanical seals which reliably prevent water ingress into the motor space. A chamber filled with environmentally friendly oil ensures cooling and lubrication of the mechanical seals even when gasladen fluids have to be pumped. Generously dimensioned ball bearings sealed for life support the stainless steel shaft. Thanks to the modular design concept, one set of spare parts will serve all four pump sizes, so that spare parts stocks – and thus costs – are reduced.
