Protium is a set of components for creating pump and reservoir combinations which increases performance, mounting options, flow inlet/outlet options and will be a feature in your build. We set out to create the most minimalistic and compact components, but at the same time providing the most options and compatibility. Our components are refined in ways only possible due to our 15 years of experience in liquid cooling. Each component is carved from a solid block of material on a CNC mill. Creating our different finishes, frosted and polished acrylic is unique and takes a lot of effort to manufacture. Protium is designed for enthusiasts who want to enjoy building systems with the freedom to create something individual.

Protium D5 Pump Top:
The Protium D5 pump and reservoir combination has three parts, Reservoir, Pump Top and Pump Cover. To create a combo only two parts are actually needed, just the Protium D5 pump top and any Protium Reservoir (this requires the use of the stock D5 retention ring).
The Protium D5 Pump Top has 5 ports, 4 inlets and 1 outlet and almost endless possibilities for mounting. The ports are designed to be able to fit even the largest fittings (16mm hardline compression fittings) on all sides and next to each other on the front. It has a unique lid design which allows the pump top to be used on its own or for a reservoir to screwed in directly. The pump top is square with ports facing at 90 degrees on all sides but one which allows for the cleanest possible loop design. The design is flow optimized which will increase performance. The finish on the polished acrylic version isn’t just a machine finished, it is actually polished which takes a lot of extra effort during manufacturing. Overall this pump top is extremely compact and minimalistic but at the same time has the most compatibility.
The D5 Pump Top has 3 sets of M4 mounting holes on 3 sides. These holes are spaced for our backplates and our Protium Pump Mount. They can also be used to mount directly to almost anything.

Superb quality but maybe it

Superb quality but maybe it would be possible to add 5mm Led holes to fit RGB LEDs?


Reservoir and pump

One gorgeous looking reservoir and pump usual workmanship of Singularity


High Quality Product, High Quality Support

Bought 2 full sets of protium pump top + reservoirs. It works really well, and it just looks fantastic. Had a slight problem with one of the reservoirs leaking fluid very slowly from the join between the reservoir and the pump top. Emailed in, and within a week, the replacement came in.
