12V DC Hot and Cooling Water Circulation Pump Benefits Efficient 12V DC brushless motor delivers reliable water circulation with low power consumption. Amphibious design allows installation in wet environments and submersion in cold water; not suitable for diving. Long lifespan and maintenance operation up to 20 years. Waterproof and lownoise performance: epoxy resin potting isolates the stator and circuit board from the rotor; ceramic shaft provides durable, quiet operation; noise level below 35 dB. Wide temperature range and broad compatibility: fluid temperatures 0 to 110 C; maximum circulating water temperature 100 C (212 F); compatible with 1/2 in NPT and female thread connections. Key specifications Power: 12 V DC Motor type: brushless Temperature range: fluid 0–110 C; circulating water max 100 C (212 F) Connections: 1/2 in NPT and female thread Submersion: suitable for submerged use in cold water; waterproof for underwater installation Noise: 35 dB What makes it stand out Combines energy efficiency with longterm reliability through a brushless motor and lowfriction ceramic shaft. Epoxy potting provides robust waterproofing for submerged or damp installations. Maintenance design backed by a claimed 20year lifespan. Flexible installation options due to dual connection compatibility (1/2 in NPT and female thread) and wide temperature tolerance. Use scenarios Domestic hot water or cooling loop: circulate hot water in residential heating or solar thermal systems, or move coolant through small cooling circuits. DIY electronics cooling and smallscale cooling loops: suitable for quiet, energyefficient circulation in enclosures, test rigs, 3D printer cooling, or compact chillers. Submerged or shallowsubmersion cooling in coldwater environments: ideal for aquariums, hydroponics, or small chiller applications where the reservoir can be kept cold.
