The Alphacool ES Solution Laing DDC310 pump serves as the foundation for various 1 to 4U server solutions from Alphacool. The unit is based around the very popular Alphacool DDC pump and has been coupled with a simple pump base to maintain compatibility with various Enterprise Solution reservoirs. Compact and powerful. The flat design of the Laing DDC310 pump saves space and fits with the corresponding Enterprise reservoirs from chassis as small as a 1U server rack. This results in a very powerful pump that can be used in the smallest of spaces. The DDC310 variant offers with a delivery height of 2.44m enough power to operate an extensive water loop. The performance is enough to operate a dual or quad socket system including reservoir and radiators. The performance of the pump is also sufficient to operate a render server with up to 4 graphics cards. Spherical Ceramic Bearing The pump uses a shaftless ball motor or spherical bearing. The motor is driven by magnets while the rotor is mounted on a ball-ceramic bearing. This makes the pump maintenance-free, as the bearing is self-adjusting and maintenance-free. The pump is lubricated by the coolant during operation. This makes the Alphacool ES Solution Laing DDC310 pump a so-called wet rotor pump. Due to its design, even small particles of dirt are no problem for the pump. Installation and Commissioning The pump is delivered with a classic plastic bottom which ensures a high compatibility to all Enterprise Solution products. However, the pump can also be mounted on all existing DDC pump tops from Alphacool. The pump comes with a corresponding O-ring, only the mounting screws must be used from the respective reservoir, as these may differ in length. The power is supplied via a 4-pin Molex connector, the speed can be read out via a 3-pin Molex connector. This is usually done via the 3-pin fan connector on the mainboard or via an appropriate fan controller.   Technical data Dimensions (L x W x H) 62 x 62 x 30mm Material Stainless steel, Carbon (FH821Z2), Ceramic (Al2O3 99,5%), Luranyl KR 2403 GW T4 (PPE+PS) , Fortron 1140L4 (PPS) Weight 170g Speed 3250 rpm Max power consumption 8W Voltage 12V DC Power connector 4-Pin Molex PWM control n/a Tacho-Signal yes (3-Pin Molex) Max. working temperature ambiente 10°C - 50°C Max. working temperature water 10°C - 60°C Max. head of pump 2,28m Max. flow 200 l/h Color black Revision DDC4.CF-XTXXWX-01 BP54
