IMO PUMP

Imo Pump is a manufacturer of rotary pumps, positive displacement pumps, screw pumps and gear pumps as well as specialty marine centrifugal pumps... During what he later described as a "boring night at a factory test room", Carl Montelius sketched out an idea for a pump with three intermeshing screws, rotating in a manner that would make them mutually sealing... A respected Swedish engineer with 60 patents already to his credit (including the first pay telephone), Montelius regarded the interesting rotors as an amusing intellectual puzzle, working almost every evening during 1923 to develop the mathematical algorithms of the threads. In 1931, Montelius linked with financier Bengt Ingestrom and formed Aktiebolaget IMO-Industri, taking the name IMO from their own names Ingestrom and Mo ntelius.
