The product is the new revision.
This pump is the first pump in the world that is used in mass-produced water-cooled workstations and is ideally suited for water cooling of processors and electronic components. Due to its size and performance, the can also be used in a variety of applications.
This DDC pump is an electronically commutated spherical motor pump with running times of well over 50,000 hours at 12 volts. The only moving part on a spherical motor pump is a spherically shaped rotor / impeller unit, which is 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 multitude of advantages: The creation of bearing play – and thus an increase in noise – is not possible due to the principle involved. This means that the pump remains quiet throughout the entire running time. The bearing is self-adjusting. It is lubricated directly by the pumped medium (wet-running pump). Maintenance is therefore not necessary.
Blocking the pump is normally not possible. A safe start-up is ensured even after a long standstill. The permanent magnetic rotor / impeller unit is driven by a magnetic field that is generated by the surrounding stator. This is built completely around the rotor. At 38 mm, the complete pump is only slightly higher than the stator itself. It fits easily into all standard PC, barebone and mini PC housings. A separate magnetic shield is normally not necessary. The spherical motor principle enables economical operation with comparatively high performance. By varying the voltage, the DDC direct current pump can be controlled easily and over a large output range. All parts in contact with the medium are completely corrosion-resistant.
