Laing DDC-1T Pump

This pump is the world's first 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 variety of applications.

This DC pump is an electronically commutated spherical motor pump with running times of well over 50,000 hours at 12 volts. The only moving part is a spherically shaped rotor/impeller unit supported on an ultra-hard, wear-resistant ceramic bearing ball. A conventional shaft with shaft bearings and seals is not present. The spherical bearing of the rotor/impeller unit on the ceramic bearing ball offers several advantages: bearing play—and thus an increase in noise—is not possible due to this principle, allowing the pump to remain low-noise throughout its entire running time. The bearing is self-adjusting and is lubricated directly by the pumped medium, eliminating the need for maintenance. As the rotor is always held magnetically in position, smaller dirt particles do not pose a problem. Blocking of the pump is normally not possible, and even after a longer standstill, a safe start is ensured. The permanent magnet rotor/impeller unit is driven by a magnetic field generated by the surrounding stator, which is completely built around the rotor. At 38 mm, the complete pump is only slightly higher than the stator itself, allowing it to fit easily into all commercially available PC, barebone, and Mini-PC housings. A separate magnetic shielding is typically not required. The spherical 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. All parts in contact with the medium are completely corrosion-resistant.
