This pump is the first pump worldwide which is used in mass-produced water cooled workstations and is ideal for the water cooling of processors and electronic components. Due to its compact size and its power it can be used for many applications.\nThis DC pump is an electronically commuted ball motor pump with an estimated lifespan of more than 50.000hrs at 12V. The only moving part on the pump is the spherically shaped Rotor unit which is sitting on an ultra-hard, wear-resistant ceramics bearing ball.\n\nA conventional shaft with bearings and seals is not used or needed. The spherical bearing of the rotor unit on the ceramics bearing ball has many advantages: The development of bearing clearance is technically impossible which results in the impossibility of noise level increase over the lifespan of the pump. The bearing is self-adjusting, making the pump consistently quiet in operation over the full lifespan. The pump is directly lubricated by the coolant (wet-running pump). Therefore no maintenance is required.\nAs the rotor is magnetically held in place even small dirt particles pose no problem for the mechanism, a blocking of the pump is not possible under normal operating conditions. Even after a long period of standstill reliable operation is ensured. The permanent magnetic rotor unit is driven frictionless by a magnetic field which is produced by the surrounding stator.\n\nThe stator is completely built around the rotor, therefore the pump is with its 38mm only slightly higher than the stator unit. It therefore fits a in almost any PC case, may it be Super tower or Barebone. A separate magnetic shielding is usually not required. The ball motor principle allows powerful yet power-saving operation. The pump can be regulated by power variations of the DC operating voltage over a wide range. All parts in touch with the coolant are completely corrosion free.\n\nTechnical details:\nDimensions (WxDxH): 90x62x38mm\nMotor: Electronically commuted ball bearing motor\nNominal voltage: 12V DC\nNominal power consumption: 18W\nCertified voltage: 6 to 13,2\nPressure head at 12V: 5,7m\nMaximum flow rate: >900l/h\nCoolant: Water /Glycol/Glycol mixtures\nMaximum system temperature: 60°C\nMaterials in contact with the coolant: Stainless steel 1.4571, PPS-GF40, EPDM O-Rings, Aluminium oxide, hard coal\nFittings: 2x 3/8" barbed fittings (For hoses with an outer diameter of 10mm and 8mm inner diameter)\n\nExtent of delivery:\nLaing DDC pump 12V DDC 3.25 18W\n\nSpeed signal: With 3-Pin Molex connector as speed signal output (for Mianboard or fan controller connection)\n\nNote: This pump is the latest revision\n\nIMPORTANT: Due to the performance of this pump, it should only be operated in a cooling loop with at least one water block. When runnning without load the pump may destroy itself.\n\nImportant: The Laing pump's electronics are not waterproof. Please make sure that the electronic components do not come in contact with water during installation or when working on the pump. When replacing the top always ensure a proper fit of the O-ring seal and avoid spills when filling the Laing reservoir. Damages due to water in the electronic components are not replaced by Laing!\n\n\nPlease note: Pump control possible with Heatmaster!\nNote: For pump control via the Heatmaster the Alphacool pump adaptor cable (Item No. 25066) is required!
