Submersible pump for large water volumes. Useful for river construction diversions and similar tasks.
It pumps water with the powerful torque of a 4-pole motor (6-pole only for U-65014B). We have selected parts with excellent wear resistance, ensuring stable performance over a long period. As a motor protection device, it is equipped with an auto cut (for 22kW and below), thermal protector, and water detection sensor (for 37kW and 55kW). This prevents motor damage due to overcurrent, overheating, and water ingress.
