SHYSKY TECH Powerful 12V Micro DC Pressure Pump DC50E-1280S, 43W 8m Lift 1000LPH, Soft Start, Magnetic Driving Centrifugal Design, Eco-Friendly, Hot Water Circulation/Pressurization / Cooling

I've tested a whole collection of different 12v pumps that were intended for aquaponic systems, and mostly the specs are a complete fantasy: the flow is nowhere near what is stated, and worse the power consumption is also much greater. The specs for this pump are really high: loads of flow at a useable head, plus reasonable power consumption. And for once they’re right on the nail. Awesome!
