Surface Ship Pumps
DESMI surface ship pumps are engineered to deliver dependable, energy-efficient performance across naval and commercial surface vessels. Combining advanced hydraulic design, robust materials and compact configurations, these pumps support critical shipboard systems where reliability, safety and efficiency are paramount.
With a proven track record in global navies and commercial fleets, DESMI provides pumping technology that meets stringent operational demands and long service life expectations in marine environments.
Pumping Solutions Tailored for Defense and Commercial Surface Vessels
DESMI designs and configures surface ship pump systems to meet the diverse operational profiles of naval defense vessels and commercial surface ships. Each system is optimised to comply with onboard safety regulations, performance criteria and mission-specific requirements.
Pumps can be supplied as standard or fully engineered packages, integrating customised drive systems, control units and pipe interfaces to ensure seamless operation in confined engine room environments. Whether supporting combat readiness, logistics operations or day-to-day commercial services, every DESMI solution focuses on operational reliability and energy efficiency.

Applications Across Onboard Systems
DESMI surface ship pumps are installed in a wide range of essential onboard systems, providing high-performance fluid handling across multiple applications, including:
-
Ballast water management and transfer systems
-
Seawater and freshwater cooling circuits
-
Fire-fighting and emergency bilge systems supported by our FineFog fire-fighting system
-
Fuel transfer and diesel oil circulation
-
Lubrication and hydraulic oil circulation
Many pump configurations can also support auxiliary operations such as scrubber water circulation, stern tube lubrication and general service water distribution, ensuring efficient and safe functioning throughout the vessel’s lifecycle.

Engineered Design and Technical Performance
Each DESMI surface ship pump is built for durability in harsh marine environments. Housings and impellers can be supplied in cast iron, ductile iron, bronze or Super Duplex stainless steel, selected to match the conveyed medium and corrosive conditions.
Dynamically balanced impellers and inducer options enable stable operation at high speeds and reduced NPSHa values.
Pumps are available for vertical or horizontal installation and can be paired with standard or explosion-proof motors, including VFD-ready configurations.
Designed for flow rates up to approximately 6,000 m³/h and pressures up to 25 bar, DESMI pumps deliver consistent performance for extended operational periods in both engine and deck machinery systems.
Compliance with Naval and Marine Standards
DESMI surface ship pumps can be supplied in designs tested to and meeting the requirements of major international classification societies such as DNV, ABS, LR and BV. For defense projects, configurations are available designed to meet naval shock and vibration standards. By aligning with global marine and defense standards, DESMI ensures compatibility with shipbuilder specifications and compliance with technical documentation for newbuild and retrofit programmes. All designs prioritise safe operation, ease of inspection and minimal environmental impact through energy-efficient performance.
Proven Global Installations and Project References
DESMI surface ship pumps operate successfully across a wide spectrum of vessels, from naval frigates, support ships and patrol boats to commercial tankers, container ships and specialised offshore vessels. Long-standing collaborations with Defense integrators and shipyards in Europe, Asia and North America underline DESMI’s role as a trusted supplier of marine pumping systems. Reference projects confirm consistent performance under variable load conditions, proving the reliability of DESMI’s hydraulic designs, material quality and engineering standards.
