Alphacool Laing DDC - 12volt Pump

This is the new revision Laing DDC.

This pump is the first one of the World which is being brought into action in serial produced watercooled workstations and is ideal for the watercooling of processors and elektronical components. Furthermore it has multiple applications due, due to its size and performance.
This DC pump is an electronical commuted ball engine pump with running periods of notedly more than 50.000 hours at 12 volt. The only moving part of a ball enginge pump is a spherical formed rotor-/ running wheel unit which bases itself on an ultra hard wear-resistant ceramic bearing ball. A conventional shaft with shaft bearings and shaft seals does not exist. The spherical bedding of the rotor-/ running wheel unit on the ceramic bearing ball offers many advantages: neither bearing clearance nor increase of noise is possible - due to this principle. So the pump stays at a low noise level during the whole running period. The bearing is self-adjusting and is lubricated directly from the pumping medium (wet running pump). This makes maintenances unnecessary. As the rotor always is magnetically held in the provided position, tiny soil particles are no problem. Normally a blockage of the pump is not possible. Also after longer standstill the pump starts confidently. The permanently magnetical rotor-/ running wheel unit is being moved by a magnetic force which is produced by the stator around. This stator is completely mounted around the rotor. Thus, the pump with its 38 mm is just a little higher than the stator itself and fits into all standard PC-, barebone- and mini-PC cases without any problem. Usually, a separate magnetical shielding is not necessary. The ball enginge principle offers an economical use with comparatively high performances. Due to voltage variation, the DCC direct current pump can be regulated very simply and at large performance range. All media contacting parts are completely corrosion resistant.
