Reef Octopus Diablo DC 5500 Variable Speed Water Pump
A New Benchmark of Aquarium Circulation PumpsThe Diablo controllable Direct Current "DC" water pumps are the latest in variable speed flow technology and allows for refined control, enhanced performance and efficiency. The vast majority of circulation pumps available to hobbyist are alternating current "AC" pumps (the type of power that comes out of your wall outlet).  Direct current pumps have several key advantages over traditional AC pumps.  Most notably, you can control the rotational speed of the motor, thus electronically control water flow rates.  DC pumps are also more efficient than AC pumps and produce less heat per volume of flow. >>> Now the aquarist can have  full control of the water flow through their sump, filters or closed loop  systems!!!Refined ControlThis controller allows users to select between six preset speeds indicated by six green LEDs.  The controller also features a feed button.  When pressed, the pump  safely shuts down and automatically reactivates after 10 minutes.  Press the feed button a second time to resume normal operation. Diablo DC pumps feature a true slow startup where the pump begins at zero RPM and ramps up to the full preset speed over a period of approximately 10 seconds.The pump and controller are connected via a waterproof 3-conductor union.  The detachable controller will allow for a simple waterproof union. The volute can rotate to change the pump's output orientation in 90 degree intervals, meaning users can output water vertically (up or down) as well as horizontally.Max Flow: 1450gph        Max Head: 10.5ftPower Consumption: 30watts at Full Speed  24V power supply (converts 100-240V 50/60Hz AC to DC)In water only!!
