Laing DDC-pump 12V DDC 4.2 PWM
This pump is the first pump in the world to be used in mass-produced water-cooled workstations and is ideally suited for the water cooling of processors and electronic components. Due to its size and performance, it can also be used in a wide variety of applications.
This DC pump is an electronically commutated ball motor pump, with operating times of well over 50,000 hours at 12 volts. The only moving part in 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 mounting of the rotor/impeller unit on the ceramic bearing ball offers a variety of advantages: The development of bearing play - and thus an increase in noise - is fundamentally impossible due to the design. The pump therefore remains quiet throughout its entire service life. The bearing is self-adjusting. It is lubricated directly by the pumped medium (wet rotor pump). This eliminates maintenance. Since the rotor is always held magnetically in the intended position, smaller dirt particles are not a problem. Under normal circumstances, the pump cannot become blocked. Reliable startup is ensured even after longer periods of inactivity. The permanent-magnet rotor/impeller unit is driven by a magnetic field generated by the surrounding stator.
This is built completely around the rotor. As a result, the complete pump is only slightly higher than the stator itself at 38 mm. It therefore fits easily into all standard PC, barebone, and mini-PC cases. Separate magnetic shielding is normally not necessary. The ball motor principle enables economical operation with comparatively high performance. By varying the voltage, the DDC DC pump can be regulated easily and over a wide performance range. All parts in contact with the medium are completely corrosion-resistant.

Why is there a Swiftech and a Laing version? Are there differences? The answer to that can quite clearly be “No.” So why are there different versions? Here is the explanation: Laing manufactures all of its pumps in Hungary. Once for the overseas market and for the German or European market. The pumps themselves are therefore completely identical. Some are labeled as Swiftech, as this is the distributor for the US market. The other versions are neutral black. The less expensive Swiftech pumps include decouplers in the scope of delivery; the Laing versions do not. Otherwise, pump performance, flow rate, etc. are completely identical. Note: The pump is the latest revision. We recommend the use of a lubricating water additive (such as AT Protect Plus or Innovatek Protect). Anti-Corro-Fluid is not recommended. The Laing pump electronics are not water-resistant. When installing or modifying the pump, please ensure that the electronics do not come into contact with water. When changing the Laing top, ensure that the O-ring is seated correctly, and when filling a Laing pump reservoir, make sure that no water overflows. Damage caused by damp electronics will not be covered by Laing.
