KSB Amarex N submersible pumps: Attention to detail is the key to cost savingsEngineering
Mississauga, Ontario, March, 2014. When designing the Amarex N series of submersible pumps, the engineers at KSB took a long, careful look at all aspects of pump operations in order to find ways of minimizing the total cost of ownership over the full pump life cycle.
Submersible pumps are widely used in wastewater processing, so minimizing clogging or blockage due to solids or fibrous materials in the waste stream was a high priority. Amarex N pumps can be ordered with impellers with built-in cutters (to reduce long pieces of fibrous material in the waste stream), vortex impellers (good for dealing with solids and dissolved gases) and screw-type impellers that feature contours that have been specially designed to avoid catching fibrous material. These pumps also feature a unique one-piece (monobloc) motor housing design that ensures accurate bearing alignment for reduced vibration and longer seal and bearing lives. Completely leak-proof cable entries help lower maintenance costs by reducing the possibility of water in the motor chamber. Meanwhile, careful optimization of the hydraulic elements improves pumping efficiency and reduces energy costs.
Amarex N pumps are available with capacities of up to 135 cubic metres per hour and heads as high as 47 metres. Special explosion-proof ATEX-certified versions are available for use in situations where there are high concentrations of flammable gases.
