Turbelle stream electronic are speed-controlled pumps operating on safety extra-low voltage to be employed in every aquarium from 200 to 2000 liters (52.8 to 528.3 USgal.) (6105) respectively with more than 3000 liters (792.5 USgal.) (6155 and 6255) for simulation of lapping waves or tidal currents. It contains a new microprocessor-controlled motor and a Turbelle controller. The pumps will be stopped immediately in case of blockage. After the blockage has been removed the pumps will start up automatically after a delay of 20 seconds. The pump driver has been provided with a fish care function which causes a revolution of the spelling propeller every twenty seconds when the pump is at a standstill. Every Turbelle stream electronic pump can be controlled by Multicontroller / SmartController 7000.For aquariums from 200 to 2000 liters (52 to 528 USgal.)Flow rate: 3000 up to approx. 13000 l/h (792 - 3434 USgal./h) with Turbelle ControllerEnergy consumption: max. 35 WPower supply unit: 100-240V / 50-60HzCable length: 5 mDimensions: o90 mm (3.5 in.)
