Engineering reliability into marine boiler systems - decades of insight behind every drop

Decades of experience go into every DESMI boiler feed solution. Engineered for reliable water flow under high temperatures and pressures, our pumps help keep marine boiler systems performing efficiently and reliably.

Understanding the real demands behind boiler feed systems

Marine boiler feed water systems operate in one of the most demanding environments on board. High pressures, elevated temperatures, and continuous operation place extreme stress on both components and system design. This is where experience matters.

Our approach is built on deep hydraulic knowledge, advanced simulation tools, and continuous feedback from vessels in operation. The result is not just optimised pump performance—but balanced systems that reduce wear, minimise energy consumption, and extend service intervals.

To support reliable operation in demanding marine environments, DESMI boiler pump solutions are developed with focus on durability, flexibility, and lifecycle efficiency:

Robust wet-end materials, including ductile cast iron and cast stainless-steel alloys, ensure reliable performance and long service life under demanding boiler water conditions.
Products are designed, assembled, and tested specifically for marine boiler applications in accordance with marine class requirements and witness inspection programmes.
A modular standardisation philosophy enables spare parts sharing across multiple engine room pump applications, helping reduce onboard spare part inventory and overall operational costs.
Both vertical and horizontal installation configurations are available, enabling flexible integration into engine room layouts where space optimisation is critical.
