This bundle includes the Alphacool Laing 12V DDC-1T Plus Pump and AGB ES Reservoir 2u - DDC Pump Top Version. This pump is the first pump worldwide which is used in mass-produced water cooled workstations and is ideal for the watercooling of processors and electronic components. Due to its compact size and its power it can be used for many applications. This 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. A 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. The Alphacool ES 2u Reservoir is a development for the Enterprise Solution series. It has an integrated pump top for the powerful DDC pump and offers many connection and mounting options. The combination of all these features provides a perfect solution for 2u server racks and workstations. The Alphacool ES 2u Reservoir - DDC version is an extremely compact reservoir especially for 2u server racks with extensive connection and mounting options. Connections: 11 x G1/4
