Diesel Driven Fire Pumps
DESMI’s diesel-driven fire pumps are engineered to ensure a dependable, high-pressure water supply for emergency fire-fighting in situations where electrical power is unavailable. Designed for defence, marine, offshore and industrial environments, these self-contained systems operate independently of the main power grid. Their robust diesel engine drive delivers essential fire water for suppression and cooling during power loss, ensuring safety and readiness even under extreme operational conditions.
Applications and operating environments
DESMI diesel engine-driven fire pumps are designed for critical applications where independent fire protection is mandatory. On naval vessels and defence platforms, they form part of onboard fire mains, providing reliable suppression capability during damage control or total blackout scenarios. In offshore rigs and industrial facilities, diesel fire pumps act as emergency backup to electric units, safeguarding personnel and assets against fire in high-risk zones.
Typical operating environments include:
-
Naval vessels and combat ships requiring autonomous fire-fighting capability
-
Offshore rigs and FPSOs demanding redundant fire water systems
-
Industrial plants, refineries and power generation sites with strict fire safety standards
-
Remote or hazardous areas where grid power cannot be guaranteed
Key benefits, safety and operational reliability
The primary advantage of DESMI’s diesel fire pumps lies in their ability to maintain high performance under power-independent conditions. With rapid automatic start-up - typically within 10 to 15 seconds - these systems provide an immediate water supply to fire mains. The autonomous design minimises reliance on external utilities, and integrated fuel storage ensures operation for up to 24 to 48 hours without refuelling.
Key operational benefits include:
-
Reliable emergency response independent of electrical power
-
Proven endurance under shock, vibration and saltwater exposure - tested and validated as part of DESMI’s shock rated pumps range
-
Low maintenance requirements and reduced downtime
-
Fuel-efficient operation with low emissions for extended missions
-
Configurable start/stop and monitoring systems for unmanned operation
These features translate into safer operations, extended service life and reduced total cost of ownership for naval and industrial operators alike.
Engineering design and technical performance
DESMI’s diesel-driven fire pumps combine compact, high-speed diesel engines with precision-engineered centrifugal pumps. The units are available in vertical or horizontal configurations, enabling flexible installation even in space-constrained machinery areas typical of naval or offshore applications.
Technical features include:
-
Flow capacity up to approximately 500 m³/h and discharge pressures up to 10-14 bar
-
Corrosion-resistant components such as bronze or stainless-steel impellers and casings suitable for seawater service
-
Automatic priming and integrated fuel tanks offering long operational autonomy
-
Advanced control panels and remote monitoring functionality
-
Compact layouts for retrofit or modular fire pump skid installations
The hydraulic design ensures stable performance, low NPSH requirements and high overall efficiency, making these systems suitable for both newbuilds and retrofit programmes within demanding defence and energy infrastructures.
