The NAUTILUS pumps are ideally suited to flat suction and following pumping out at full power, a minimal water volume remains

The flat suction is fully integrated into the pump, which makes the removal of the suction grill or the mounting of an additional device unnecessary

  • Certified according to DIN 14425 type 4/1 and the "Submersible Pumps" standards of the Austrian Federal Fire Brigade Association (ÖBFV)
  • 20% more power than the minimum requirement indicated in the standard for 1 bar
  • Conveys dirty water up to a grain size of 8 mm
  • Suctions water up to a water level of approx. 4 mm. Doing so requires neither the removal of the suction screen, nor an additional device mounted on the pump.
  • Slim design for space-saving mount in the vehicle
  • Suitable for use in tight shafts and wells
  • Low weight of only 21 kg
  • High starting torque with low power consumption thanks to double capacitor control. Operation is possible using a generator with min. 3 kVA.
