OcUK Tech Lab 18w DDC Pump & EK-DDC X-RES 140 CSQ Value Combo

Assembled in house by Expert OcUK Technicians

The DDC provides supreme performance alongside a tiny footprint.

This high performance aftermarket pump top for Laing DDC series water pumps with integrated reservoir offers increased hydraulic performance (up to 15%) compared to factory top.

Every OcUK DDC & EK X-RES combo is assembled by an Expert OcUK technician and tested for quality assurance before it ships to the customer.

Laing 18W DDC-Pump 12V DDC-1T Specifications
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.
As 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 frictionlessly driven by a magnetic field which is produced by the surrounding stator.

The 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.

Flawed by design

The pump itself seems a good idea with the magnets, but placing it directly under the reservoir is not. The pumpt is just put under the tank with a single ring of rubber protecting the open circuit board from the liquid. There are star-screws with a tiny head holding it in place to put pressure on the ring that cannot be tighend enough.
I had one pumpt lasting 1.5 years (put together by overclockers) and now another lasting only two month (put together by myself) before liquid got through and killed the pump.
