In total DAC Electric developed three unique and tailor-made motors for the special fish-friendly pumps from Hofmeijer Mechanics and Pumps. The motors are compact, robust, water-proof and extremely efficient due to the permanent magnet construction. Powers range from 2,2 up to 8,3 kW, speeds range from 300-600 rpm. Due to their compact design, it is possible to implement higher powers in existing pumpwell’s therefore significant changes to well foundation and constructions belong to the history.
