This pump is the world's first pump to be used in mass-produced water-cooled workstations and is ideal for water cooling processors and electronic components. Due to its size and performance, it can also be used in a wide range of applications.

This DC pump is an electronically commutated ball motor pump with a running time of well over 50,000 hours at 12 volts. The only moving part on a ball motor pump is a spherically shaped rotor/impeller unit supported on an ultra-hard, wear-resistant ceramic bearing ball.

There is no conventional shaft with shaft bearings and shaft seals. The spherical bearing of the rotor/impeller unit on the ceramic bearing ball offers a number of advantages: Bearing play - and thus an increase in noise - is not possible due to the principle. The pump therefore remains quiet throughout its entire service life. The bearing is self-adjusting. It is lubricated directly by the pumped liquid (wet-running pump). Maintenance is therefore not required. As the rotor is always held magnetically in the intended position, small dirt particles do not pose a problem. Blocking of the pump is normally not possible. Even after a longer standstill, a safe start-up is guaranteed. The permanent magnet rotor/impeller unit is driven by a magnetic field generated by the surrounding stator.

This is built completely around the rotor. At 38 mm, the complete pump is therefore only slightly higher than the stator itself. It therefore fits easily into all commercially available PC, barebone and mini PC housings. A separate magnetic shield is not normally necessary. The ball motor principle enables economical operation with comparatively high performance. By varying the voltage, the DDC DC pump can be easily controlled over a wide power range.
