Initially the main activity was the importation of foreign marine equipment to Norway. After World War II, Frank Mohn AS began developing and manufacturing its own products such as emergency generator sets for link communication and emergency firefighting pumps.
Frank Mohn’s international activities began with the introduction of high pressure hydraulically driven pumps in the early sixties. Frank Mohn AS was then among the first in applying hydraulic drive to marine pumps. The hydraulic drive on marine pumps had the advantages of low weight, stepless capacity control and no explosion risk. At first the Framo range consisted of dredge pumps, fish pumps and chemical pumps delivered as portable submersible units.
