Featuring a unique ceramic ball bearing rotor for ultra-quiet, maintenance-free operation, it delivers up to 505 L/h flow at 18W power consumption. With a robust 50,000-hour lifespan and corrosion-resistant materials, it integrates easily via a 3-pin Molex tacho connector for real-time monitoring, making it a top choice for professional-grade cooling setups. ## Description This pump is the first pump worldwide which is used in mass-produced water cooled workstations and is ideal for the watercooling of processors and electronic components. Due to its compact size and its power it can be used for many applications. This DC pump is an electronically commuted ball motor pump with an estimated lifespan of more than 50.000hrs at 12V. The only moving part on the pump is the spherically shaped Rotor unit which is sitting on an ultra-hard, wear-resistant ceramics bearing ball. A conventional shaft with bearings and seals is not used or needed. The spherical bearing of the rotor unit on the ceramics bearing ball has many advantages: The development of bearing clearance is technically impossible which results in the impossibility of noise level increase over the lifespan of the pump. The bearing is self-adjusting, making the pump consistently quiet in operation over the full lifespan. The pump is directly lubricated by the coolant (wet-running pump). Therefore no maintenance is required.
