Military Off the Shelf Pumps
DESMI’s Military Off the Shelf (MOTS) pumps are designed for naval and defence operators who demand mission-ready performance and proven reliability. Built on more than 185 years of engineering expertise, our MOTS portfolio combines standardised designs with military-grade
durability, ensuring dependable operation across vessels, bases and mobile defence units. These pumps deliver consistent flow and resilience in critical systems where downtime is not an option.
Engineered for Harsh and Demanding Military Environments
DESMI’s defence and naval pumps are constructed to perform reliably under the harshest operational conditions. Each unit is built to maintain full functionality under vibration, prolonged exposure to temperature extremes and shock events. Shock-rated configurations are tested to remain operational before, during and after impact incidents, ensuring continuity of service in demanding maritime and defence environments. Components are manufactured from robust materials that resist corrosion and wear, ideal for saltwater, fuel and hydraulic service applications common in naval operations.

Key Benefits and Operational Reliability
DESMI’s MOTS and shock-rated pumps are designed for effective operation and a low total cost of ownership. With efficient hydraulics and durable mechanical components, they deliver high energy efficiency and extended service life. Their modular design simplifies maintenance, while standardised components ensure straightforward spare part availability. Over decades of use in defence and naval fleets, DESMI has demonstrated that robust design translates directly into maximised uptime and operational certainty under mission conditions.
Design and Technical Features of Defence Pump Solutions
Our defence portfolio includes a comprehensive range of centrifugal, priming and self-priming designs, both vertical and horizontal. MOTS units are available in electric and diesel-driven configurations, suited for either stationary or portable installations. Shock-rated centrifugal pumps are engineered with reinforced casings and shaft assemblies to resist stress under mechanical shock. Diesel fire pumps and electric emergency fire pumps are part of the same modular family, allowing easy integration across different vessel and base types. Each pump is built for optimal hydraulic performance, with low NPSH values, a compact installation footprint and ease of service in confined environments.
Shock Qualification, Testing and Military Compliance
DESMI’s defence pumps are designed and tested to meet demanding military requirements for shock and vibration tolerance. Selected designs are available in configurations tested to recognised naval shock qualification regimes, maintaining hydraulic efficiency without compromising durability. Each product undergoes rigorous quality control and functional testing before deployment, ensuring consistent compliance with military expectations. Our engineering approach focuses on survivability and recoverability - keeping pumping systems operational before, during and after impact.
