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.

Such great product!

Beautifully made, great finish, presents well in my system.


Just awesome

Very solid product, screams quality. Plenty of ports that allow to be flexible with custom loop, aesthetics is just amazing. Overall I am very happy that I have decided to include it in my loop.

Amazing product

The greatest finish I’ve ever seen on an acrylic product. The 4 ports are mush appreciated but I think you should show more the fact that you can (should) put 3mm leds in it, just like at the top of the reservoir. Great job SC team!!!


Amazing Product - Even better Customer Service!

Looks incredible. Originally shipped with incorrect ring but I was emailed the same day letting me know and the correct one was shipped out the next day. Had an issue during custom loop setup and Samantha with Singularity was AMAZING. Thanks guys/gals!!

Everything is great, except.

As the title says everything is great, except the the top cap had a little black spot that can’t be removed.
