Pumps & reservoirs,
the loop's quiet engine.
Three-in-one pump-reservoir-manifold combinations built around PWM-controlled D5 pumps. The reservoir, the pump, and the distribution manifold sit on a single chassis-mountable assembly — fewer fittings, fewer leak paths, and a fixed pressure envelope across the workstation catalogue.

Single pump or dual pump, same loop discipline.
Single D5
X3 and X6 — single PWM D5 pump
One PWM-controlled D5 pump driving the loop, with three- or six-way manifold outputs depending on chassis density. The single-pump configuration suits typical workstation builds where heat rejection capacity tracks GPU count.
PWM-controlled · 30 000 Pa max in the loop
Dual D5
X11 — dual D5 pumps in series
Two PWM-controlled D5 pumps arranged in series for redundancy and headroom in higher-density workstation builds. A pump failure does not stop the loop — the second pump carries flow until the first is replaced. Eleven-way manifold output.

Standalone or combo?
The right choice depends on chassis geometry, whether you are adding to an existing loop, and whether you need the pump and reservoir to be co-located. Tell us the build and we'll confirm which configuration fits.
