Avoiding disturbances to class-approved equipment

Green & safe pumping

Specialising in the development and installation of efficient and safe pump solutions for the global marine industry, DESMI is constantly looking to optimise their product and solutions portfolio.

Frequency converters are often applied in pump installations to increase their efficiency, slashing both fuel consumption and CO 2 emissions. An unfortunate side effect is that frequency converters can create disturbances in other class-approved equipment onboard vessels.

Designed specifically for installations with frequency converters generating AC voltage down to 5 Hz, DEIF’s SIM-Q LF (Low Frequency) counters that issue, and it has now become the preferred choice when DESMI markets pump solutions in the marine industry.


Founded in 1834, DESMI today stands out as a global company specialised in the development and manufacture of pump solutions for marine, industry, oil spill combating, defence & fuel and utility both locally and globally.
