Rosenbauer launches FOX S portable fire pump
Rosenbauer has presented its new FOX S portable fire pump at the FLORIAN trade fair in Dresden.
The company said the FOX S delivers 1,050 litres per minute at 10 bar, allowing a B-hose line to be supplied with 1,000 litres per minute over long distances.
Weighing 154 kilograms, the pump is compact and easier to handle and transport than the larger FOX model.
Rosenbauer confirmed that the FOX S completes its portable pump portfolio, joining the FOX, BEAVER and OTTER models.
Roland Weber, Product Manager at Rosenbauer, said: “The FOX S is the ideal choice when every kilo of weight counts, but all the functions of a FOX are important.
“It impresses with the robust technology that fire departments around the world appreciate about our products.”
Lightweight design with robust efficiency
According to Rosenbauer, the FOX S features a single-stage centrifugal pump developed specifically for this application.
Its impeller, designed with spatially curved blades and a light metal spiral housing, delivers high efficiency.
A stainless-steel pump shaft, lubricant-free mechanical seal and clamping ring design make the unit easy to maintain.
The company said the FOX S is operated at the push of a button and uses the Rosenbauer Logic Control System (RBC LCS) interface for user feedback and fault reporting.
Cavitation warning and inlet pressure monitoring protect the pump from damage during use.
The system also includes mechanical overheating protection that drains hot water above 60°C and allows cooler water to flow in.
Power and control for global conditions
Rosenbauer said the FOX S is powered by a two-cylinder BRP-Rotax in-line engine with electronic control.
The water-cooled engine is designed for use in both hot and cold climates.
A 20-litre fuel tank supports extended operation, and refuelling during use allows continuous pumping.
Rubberised, foldable handles enable safe carrying, and quick-fit wheels allow one-person transport.
Lighting can be fitted to the carrying frame for night operation, and an external control unit allows pump-and-roll or vehicle-based operation.
Expanding Rosenbauer’s portable pump family
Rosenbauer stated that the FOX S and the larger FOX share a unified operating concept, meeting performance standards across the PFPN 10-1000, 10-1500 and 10-2000 classes.
The FOX remains Rosenbauer’s most powerful portable pump, with a flow rate of 2,050 litres per minute at 10 bar and a suction lift of three metres.
The BEAVER model was also updated in 2025 with a new engine, redesigned controls and improved ergonomic handles.
The company said the BEAVER, weighing 133 kilograms, exceeds its PFPN 10-750 class requirements with an output of over 900 litres per minute.
At 58 kilograms, the OTTER serves as the lightweight entry-level model, providing easy handling and reliable water delivery in the field.
Weber added: “BEAVER and OTTER stand out for their exceptional ease of use and maintenance.
“They can be transported to the scene with minimal effort and provide firefighting crews with a reliable and long-lasting water supply.”
Availability and delivery timeline
Rosenbauer confirmed that the FOX S will be available to order from January 2026.
Deliveries are expected to begin at the end of the first quarter of 2026, depending on order intake.
Relevance for fire and safety professionals
The FOX S is designed for firefighting teams requiring portable pumping solutions with high output and low weight.
Its compact size and simplified transport features could support municipal, rural and volunteer fire departments that operate in terrain where vehicle access is limited.
Procurement officers and operations managers may find the shared control interface across the FOX family useful for training standardisation and equipment compatibility.
The pump’s mechanical safety systems, including cavitation protection and automatic cooling, are relevant for maintenance personnel overseeing prolonged or remote pumping operations.
The January 2026 release date provides a clear window for equipment planners considering replacements or upgrades ahead of the next procurement cycle.
