The D-D Funktion pumps are a multi-function DC pump with a unique digital controller, featuring three wave modes and a constant running setting. These pumps are suitable as a return pump or for running media reactorsSuitable for salt or freshwater use, the sine wave technology and low voltage motor offers ultra-low running noise, low heat output and energy efficiency.FeaturesFull range of high flow pumps with a compact footprintUnique digital controller with 3 wave functions and a constant flow modeSine wave technology for low running noiseLow voltageEnergy efficient motorSuitable for saltwater and freshwaterWear resistant ceramic shaft and bearingsDetachable footplate with anti vibration rubber feetSplash proof connection between the pump and controllerFlexible Installation OptionsAll models are fully submersiblePump outlet can be positioned to face upwards, left or right‘Elephant Nose’ suction attachment included, for anti-vortex operationStandard suction cage included for normal submerged useQuick couple unions included for simple pump removalMultiple pipe connections includedController FeaturesUnique multi-function digital controller with touch button padBack-lit LCD colour display with adjustable screen brightnessMulti-language display with screensaver4 different flow modesAdjustable minimum and maximum power settings in wave and pulse modes.Adjustable maximum power on pump modeFeed mode and on/off functionsRun-dry detection with automatic shutdown functionDetachable mounting bracketWave ModesPump - The pump can be set to run continuously for use as a standard return, reactor or equipment supply pump. Flow setting can be adjusted on the controller between the minimum and maximum power settings of 30 and 100.Wave - A constant wave output Is created as the pump ramps up and down between a minimum and maximum power setting. The frequency and power settings can be changed on the controller.Pulse - The speed of the pump will alternate between a low and high power setting and can be used to set up a standing wave. The frequency and power settings can be changed on the controller.Storm - Output of the pump will alternate and ramp between different power settings, at a varying frequency to form a random flow pattern. Ideal for stirring up detritus so it can be removed by filtration.
