The new bilge pumps feature an internal level sensor that activates when the water reaches a height of 5 cm and deactivates when the water is removed (Auto Sense Intelligence). In case the level sensor becomes contaminated with debris or polluted water, the unique backup function prevents the continuous operation of the pump, protecting the battery while maintaining automatic operation. The pumps are also equipped with a check valve to prevent the backflow of water, avoiding unpleasant odors.
