Laing Vesijahutus DDC-Pump 12V DDC 3.25 18W (49119)

This pump is the first in the world to be used in mass-produced water-cooled workstations and is ideal for cooling processors and electronic components. Thanks to its compact size and power, it can be used for many applications. This DC pump features an electronically commutated ball motor with an estimated lifespan of over 50,000 hours at 12V. The only moving part in the pump is the spherically shaped rotor unit, which sits on an ultra-hard, wear-resistant ceramic bearing ball. Traditional shafts with bearings and seals are not used or needed. The spherical bearing of the rotor unit on the ceramic bearing ball offers several advantages: the development of bearing clearance is technically impossible, which ensures that the noise level will not increase over the pump's lifespan. The bearing is self-adjusting, which means the pump remains consistently quiet throughout its life. The pump is directly lubricated by the coolant (wet-running pump), so no maintenance is necessary. Since the rotor is magnetically held in place, even small dirt particles will not affect the mechanism, and the pump cannot be blocked under normal operating conditions. Reliable operation is guaranteed even after long periods of inactivity. The permanently magnetic rotor unit is driven frictionlessly by a magnetic field produced by the surrounding stator. The stator is built completely around the rotor, so the pump, at 38mm, is only slightly taller than the stator unit. This allows it to fit into almost any PC case—be it a super tower or a barebone. Separate magnetic shielding is usually unnecessary. The ball motor design allows for powerful yet energy-saving operation. The pump’s output can be adjusted across a wide range by varying the DC operating voltage. All components in contact with the coolant are completely corrosion-resistant. Pump tachometer: Features a 3-pin Molex connector as a pump tach output (for mainboards or control units). Why are there Swiftech and Laing versions? Are they different? The answer is simple: No! Here’s why: Laing manufactures all pumps in Hungary; they are just labeled differently for overseas and European markets. The pumps themselves are exactly the same. The overseas version is distributed by Swiftech and the European one is neutrally black. Swiftech pumps are usually shipped with decouplers, while Laing pumps usually are not. The power, pressure head, and flow rates, etc., are all identical. Important: The electronics of the Laing pump are not waterproof. Please ensure the electronic components do not come into contact with water during installation or maintenance. When replacing the top, always ensure the O-ring seal is properly fitted and avoid spills when filling the Laing reservoir. Laing does not cover damages caused by water in the electronic components!
