Product information

"18W DDC-Pump 12V DDC-1T Plus"

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.

Great Pump

I am using it as a replacement for an original Zalman Reserator 1 v2 pump, and it is simply great! Very low noise and it is being able to push 2.5l of water from the Reserator through the system (GPU+CPU+SB) with no sweat. To make it virtually inaudible I added the EK top and put some damping foam on the bottom. It is really capable pump, cools my OC'ed Core i5 2500K 4.7Ghz to 60C under load, and HD's 7850 GPU to 50C at full speed and max OC 1450Mhz, just with Zalman's Reserator as a heat exchanger. Soon I will be adding another 120mm rad with a fan to the system and I am sure the pump will still act perfectly...

Pump it up

This is a cracking pump I bought two of these to go into my Koolance res (which also looks amazing).

The pumps are super quiet in my shiny corsair 800d. They seem to pump the fluid around really fast and efficiently. I have two loops one to the CPU and one to my graphics. Although I have no oced my CPU yet. The graphics go through a EX 360 rad and through 3x 480GTXs in series. I have an oc of 800mhz core at 1088mv and the max temp I have seen on them is 46c. I could probably do with ocing them a bit more. But I'm fairly happy with that at the moment.

End result great small pump that does its job extremely well and ultra quiet.
