NAUTILUS Rosenbauer Technical Equipment.
Small pump. Powerful performance. Certified according to DIN 14425,
submersible pumps for fire departments The first choice for high water and flooding
Every second counts when high water or flooding occurs. Reacting quickly and pumping the water out of spaces and trenches prevents consequential damage as well as consequential costs. The NAUTILUS submersible pump from Rosenbauer gets into every nook and cranny and even pumps waste water away with virtually no residue. Developed for use under the most difficult conditions, the NAUTILUS even works well in small, cramped spaces, low-lying cellars, under passes, parking garages, or tight shafts.
Sleek in its design and equipped with a reliable electric motor, the NAUTILUS is easy to carry and can be deployed wher ever large pumps or portable fire pumps cannot go. It can even be quickly and easily transported and operated by just one person
The benefits of the NAUTILUS in operation:
Ease of use
▪ Easy to transport by one or two people
▪ Standing, lying, or submerged operation
▪ Broad range of applications thanks to compact design
Rapid intervention
▪ Immediate startup in just a few simple steps
▪ High output and low weight
▪ Rapid elimination of water, sludge, and sand
Residue-free pumping
▪Maximum suction performance down to 4 mm (5/32″) water level with the NAUTILUS 4/1 and 4/1 ECO, 8 mm (5/16″) water level with the NAUTILUS 8/1
▪Making clean-up work easier
▪ Saving time and effort
Small, light, and powerful.
The NAUTILUS submersible pump from Rosenbauer has been successfully used in disasters for many years. It contains all of Rosenbauer’s know-how from over 100 years of experience in pump technology. With its many benefits in operation, the high carrying comfort, and the excellent pump performance even in difficult terrain, it is the pump of choice for fire departments in cases of high water and flooding. Rapidly on-site, it is immediately ready to use and pumps the water away quickly and effectively
Minimum weight. Maximum performance
Integrated flat suction without retroffitting
The integrated flat suction device enables water to be pumped out down to a few millimeters. The NAUTILUS 4/1 and 4/1 ECO pumps suck out down to 4 mm (5/32″) resid ual water and the NAUTILUS 8/1 down to 8 mm (5/16″)
residual water.
The big advantage: In contrast to many submersible pumps on the market, no additional components have to be added to or taken off the NAUTILUS
Powerful at startup
Thanks to its starting capacitor, the pump is powerful at startup even with little nominal current. There are suitable NAUTILUS submersible pumps for generators from only 3 kVA .
Wastewater-capable pump performance
A powerful submersible pump must also be able to pump contaminated water with sand, mud or grit. The NAUTILUS 4/1 and 4/1 ECO convey dirty water up to a grain size of 8 mm (5/16″), and for the NAUTILUS 8/1 up to 10 mm (25/64″).
Small Pump – Great Job
The NAUTILUS submersible pumps are THE pumps for flood operations. Small and cramped spaces, flooding in low-lying cellars or narrow shafts, these are precisely the operational scenarios for the NAUTILUS submersible pumps. Where larger pumps or portable fire pumps are difficult to transport, the NAUTILUS submersible pumps are perfect for use thanks to their small size and low weight
Low weight
A real advantage of the NAUTILUS submersible pump is its low weight. The combination of light weight, compact design, and powerful flow rate make it unbeatable.
Easy to carry
Thanks to the ergonomically shaped carrying handle, the NAUTILUS submersible pump is easy and comfortable to carry by a single person or two crew members.
Service-friendly and low maintenance
For maintenance work in the area of the impeller, the pump is simply placed
on its head, without the help of a second person. As the suction strainer is only fixed with three screws, it can easily be removed to clean the impeller as quickly as possible of wedged or stuck foreign material. For a maximum service life, the pump is simply flushed with clear water after every operation
Robust and durable
The robust NAUTILUS submersible pump is virtually indestructible and
extremely durable. As the pump only has a few electronic components and these are doubly separated from the wet area, it is extremely reliable and fail-safe. If the impeller should block, the motor protection automatically turns the motor off and saves the pump from possible motor damage
Slim design
A crucial benefit of the NAUTILUS submersible pump is its compact
design. This predestines it for all operational purposes in tight spaces, narrow shafts, and low-lying wells. Its streamlined shape also ensures for easy and space-saving fastening in the fire fighting vehicles.
100% waterproof
To enable the NAUTILUS submersible pump to work under water, it must be completely sealed. Thanks to the two-part protection of the electronics area from the wet area of the pump, not a single drop of water gets into the motor housing or the electronics. An inspection opening in the area of the wet zone enables a regular check of the operational readiness.
Tried and tested technology – compact design
To make the NAUTILUS even more flexible, user-friendly, and faster, Rosenbauer has modified the design of the tried and tested submersible pump. What was kept is the Rosenbauer pump technology, which has been tested in practice. The ergonomics and safety are an added plus. In particular the cover of the submersible pump shows the benefits of the re-design
One idea – three options
It is one of Rosenbauer’s main missions to always offer emergency crews the maximum in performance and quality. The performance data of the NAUTILUS submersible pump models is well above the required values of DIN standard 14425 for portable submersible motor pumps with electric drive for fire departments
