• Powerful at start-up with little power thanks to starting capacitor: NAUTILUS 4/1: Operation with power generator from 5 kVA
• Integrated motor protection relay protects the submersible pump against damage
• A higher intake strainer has plenty of suction inlets even in case of partial contamination – high pump performance is guaranteed
• Flat suction down to 4 mm without additional components that have to be attached or dismantled
• Oil and maintenance-free electric motor
• Inspection opening for checking the mechanical shaft seal
• Ergonomically shaped carrying handles make carrying comfortable for one or two person(s)
• More space in the coupling area so that attaching and detaching the hoses is easier and faster (can be equipped with all standard coupling systems)
• Can be fitted with all common coupling systems
• More space near the lifting eyelet guarantees compatibility with every carabiner for fast and reliable attachment
• The pump can be easily turned upside down in the area of the impeller for maintenance work without help from a second person (when using a Storz B coupling)
• Because the suction strainer is mounted with only three screws, it is easy to remove and, therefore, it is possible to free the impeller as quickly as possible from cords, etc.
• Compatible with existing vehicle mounts

The NAUTILUS 4/1 is also available as a practical submersible pump set, consisting of:

• NAUTILUS 4/1 with Storz B coupling

• Tested according to DIN 14425 - TP 4/1 and the "Submersible pumps" norm sheet of the Austrian Fire Brigade Association (ÖBFV)
• Specially developed for operation with smaller 3 kVA generators 

• Certified according to DIN 14425 type 8/1 and the "Submersible Pumps" standards of the ÖBFV
• 17% more power than the minimum requirement indicated in the standard for 1 bar
• One of the strongest pumps in its class
• Conveys dirty water up to a grain size of 10 mm
• Suctions water up to a water level of approx. 8 mm
• At only 30 kg, one of the lightest submersible pumps on the market
• Rotation direction display on the CEE motor protection on/off switch. The rotation direction is easily altered, if necessary, using the phase changer on the plug.
• Can be operated upright, on its side or fully submerged 

The NAUTILUS is the first submersible pump from Rosenbauer with an electric drive. Tested and certified according to DIN 14425 and the "Submersible Pumps" standards of the Austrian Federal Fire Brigade Association (ÖBFV) NAUTILUS conveys dirty water up to a grain size of 10 mm (model 8/1) or 8 mm (model 4/1). The pump can be operated upright, on its side or fully submerged.

• Low weight: NAUTILUS 8/1 with only 30 kg total weight (including cable) and NAUTILUS 4/1 at 23 kg
• Two handles bent outward for comfortable gripping
• The pump is easily carried by one or two persons
• The positions of the handles prevent the NAUTILUS from colliding with the feet when carrying
