Eheim CompactON 1200 High-Performance Low-Power Silent Aquarium Water Pump

EHEIM CompactON 12000 Pump is the most powerful pump in the CompactON lineup, delivering up to ~3170 gallons per hour (12,000 L/h) of water flow. It’s designed for very large aquariums, ponds, or high-demand applications such as large filters, multi-tank systems, or extensive water features. This pump combines high output with a relatively compact and submersible design, giving you flexibility in installation. It has an adjustable flow regulator for controlling the massive flow rate and comes with multiple hose adapter sizes. Running smoothly and quietly, the CompactON 12000 uses quality ceramic shafts and bearings to ensure durability under continuous operation. It’s protected against running dry and easy to maintain (the impeller can be accessed for cleaning). When you require robust water movement—like simulating strong river currents for certain fish or feeding a large UV sterilizer—this pump handles the job with efficiency and the engineering excellence you expect from EHEIM.
