Cargo Pumps
A safe, efficient and reliable cargo pump The NDW pumps from DESMI are energy efficient and well proven for pumping every media from LPG, to LEG over a wide range of chemicals, through to CO₂. If you start to count and visit cargo ships sailing around the world, you will notice that many DESMI Deepwell pumps are installed and in use. The number of parts and the efficiency of the pumps have been improved based on the operational experiences from our existing pumps and by means of modern design tools and our in-house test facilities.
Scrubber pumps
Vertical In-line Centrifugal Pump in stainless steel DN 65 to 400, Up to 1800 m3/h Market Leader at both Sea and Land DESMI has manufactured pumps and pumping solutions for more than a century and in recent years our expertise in pumps for scrubber solutions has increased significantly, which makes us a unique partner for delivery of pumps for scrubber systems for all types of vessels and landbased applications.
VAC Centrifugal Pump
A new generation of dirty water vacuum pumps A new generation of dirty water vacuum pumps, based on the principle of the liquid ring system. This compact pump combines all performances of diaphragm, piston and centrifugal pumps and will pump continuously, by means of the specially developed rotor, on liquids, air or gasses in any mixture.
Modular S Centrifugal Pump
Self-priming Centrifugal Pump Up to 400 m3/h (1760 US gpm) The Modular S Centrifugal Pump represents one of the most distinctive products of self-priming pumps. On the basis of 50 years of experience in the production of self-priming pumps we produce a pump series that meets the future demands for economical and reliable pumps. The Modular S is widely used within different applications and markets.
Methanol Pump - Magnetically Driven for alternative fuels
DESMI's high-efficient & reliable Methanol Pumps are revolutionising the safe handling of alternative fuels. Due to its seal-less design, the mag-drive pump is the perfect match when handling new marine fuels, as they can be environmentally sensitive. Magnetically Driven Methanol Pump The quest for greener alternatives to traditional fossil fuels is essential, yet it comes with its own set of challenges. New fuel types such as methanol are often toxic or hazardous, necessitating stringent isolation measures and double-walled piping systems. Insulated composite cannister, designed to eliminate eddy loss, and ensure low power consumption. High-quality material and optimal structure secure the pump maximum working pressure up to 16 bar. With its compact design and small footprint this pump offers convenient and flexible installation, particularly in enclosed spaces. Built-in PT100 allows for monitoring of coupling temperature risk. Leakage probe option can be used to detect any leaks from the cannister.
