12V DC Brushless Miniature Waterproof Centrifugal Pump Key benefits — why you need it Fast, reliable cooling: Delivers a 240 L/H flow rate at 1800 RPM to remove heat quickly from compact systems and load components. Quiet operation: Designed to run below 40 dB so it cools without adding distracting noise to workstations, labs, or equipment enclosures. Long, lowmaintenance life: Brushless motor and engineeringplastic construction provide dependable operation for more than 20,000 continuous hours. Spacesaving, weatherresistant design: Small footprint and waterproof construction let you install the pump in tight, damp, or harsh environments. What it does and how it solves problems Heat management: Moves water fast enough to stabilize temperatures in small cooling loops, preventing thermal throttling and component failure. Vibration and noisesensitive applications: Low noise and smooth brushless operation keep systems quiet and reduce mechanical wear compared with brushed pumps. Durable continuous operation: service life reduces replacement frequency and maintenance costs in continuousduty installations. Key specifications and compatibility Supply: 12V DC, brushless motor Flow rate: 240 L/H Speed: 1800 RPM Maximum lift/head: 3 meters Noise level: <40 dB Inlet/outlet: 8 mm Size: 55 × 34 × 41 mm Materials: Engineering plastics; waterproof centrifugal design Rated continuous life: >20,000 hours Installation and fit Compact dimensions and 8 mm ports make the pump compatible with standard smallbore tubing used in electronics cooling and compact fluid systems. Waterproof housing allows installation inside enclosures or near moistureprone areas without special sealing. Brushless 12V operation integrates easily with common DC power supplies used in industrial controllers, PC systems, and automotive electrical systems. Practical use scenarios Small server racks or workstation liquidcooling loops: Maintain stable temperatures for CPUs, GPUs, or compact inline heat exchangers in confined spaces. Industrial equipment circulation: Provide continuous coolant flow for sensor housings, laser cooling modules, or precision manufacturing tooling where quiet, reliable operation is required. Laboratory or hobby systems: Support benchtop test rigs, small aquarium circulation, or robotics cooling where compact size and waterproofing simplify installation. Why choose this pump Balanced performance, size, and durability for applications that need continuous, quiet, and efficient liquid circulation. Brushless technology and engineering plastics reduce maintenance and extend operational life compared with conventional brushed pumps. Straightforward integration with 12V systems and common 8 mm tubing lets you deploy it quickly in a variety of environments.
