The Seltz D DC universal pump by Hydor is versatile and ideal for both marine and freshwater aquariums, both for wells or biological filters and for use in sump. Safe, thanks to the low voltage operation, it ensures excellent performance with reduced energy consumption. With the electronic controller it is possible to adjust the flow rate in six different intensities. In addition, the Feed Mode can be activated with the dedicated button, which pauses the pump for 5 minutes and allows the feeding of the fish.The pump can work both in and out of the water, maintaining the same silence and respecting the environment. The anterior chamber can be rotated and therefore adapts to the different needs of use. In case the water flow is less than optimal for operation, a sensor located inside the motor shuts down the pump to prevent damages. In addition, a special internal anti-vibration mechanism and the rubber feet guarantee stability even in adverse conditions.Seltz D DC is available in various models with different flow rates, power and max head.Cleaning tips: remove dirt and limescale from the rotor and its seat with a soft brush, do not use detergents or solvents. Clean the grids with running water. In the event of a drop in performance or noise, restart the pump to eliminate the air trapped inside.
