FW submersible pump "NAUTILUS" 4/1 - STORZ B

• Small pump - powerful performance, the NAUTILUS is the small disaster relief worker with a big impact
• Certified according to DIN 14425 Type 4/1; furthermore tested according to EN 60335-2 for use in domestic settings
• This pump is distinguished by its combination of weight, compact design and high flow rate.
• The delivery rate of the NAUTILUS exceeds the minimum standard requirement of DIN 14425 at 1 bar; this submersible motor pump is therefore one of the most powerful pumps in its class (20% higher performance than required by the standard).
• Designed for use under the toughest conditions, the NAUTILUS also works optimally in small, cramped spaces, deep basements, underpasses, underground garages or narrow shafts.
• The integrated flat suction device allows water to be pumped down to a residual water level of 4 mm; neither the suction grill needs to be removed nor does an additional device need to be mounted on the pump.
• The NAUTILUS 4/1 pumps contaminated water with a particle size of up to 8 mm.
• Thanks to its ergonomically shaped carrying handles, the NAUTILUS submersible pump is easy and comfortable to carry by a single person as well as by two emergency personnel.
• The large carrying handles on the right and left of the pump cover are equipped with cold protection.
• 100% waterproof – thanks to the double seal, not a single drop of water can penetrate the motor housing or reach the electronics; an inspection opening in the wet zone allows for regular checks to ensure operational readiness.
• The NAUTILUS submersible pump is equipped with a 20 m long cable type H07RN-F; the cable length ensures that there is no plug connection in the wet area; to prevent damage in the cable routing area, the pump cover features a cable holder including integrated strain relief.
• For maintenance work on the impeller, the pump is simply turned upside down without the need for a second person; since the suction strainer is fixed with only three screws, it can be easily removed to quickly clean the impeller of any jammed or stuck foreign objects; for maximum service life, the pump is simply rinsed with clean water after each use.
