Thermaltake CL-W083-PL00BL-A Pacific PR22-D5 Pump/Reservoir Combo

The Thermaltake Pacific PR22-D5 is an all-in-one pump and reservoir unit built around the proven D5 pump platform, a motor widely trusted in the custom water cooling community for its durability and consistent performance. With a maximum flow rate of 1135 liters per hour and a maximum head pressure of 15 feet, the PR22-D5 delivers enough force to push coolant through dense radiators, multiple water blocks, and long tubing runs without struggling. The five manually selectable speed settings—ranging from a near-silent 1800 RPM up to a full-power 4800 RPM—give builders direct control over how aggressively the pump operates.

What sets this unit apart from a standalone D5 pump is the integrated 300ml PMMA reservoir and the included aluminum sound proofing kit. The reservoir simplifies loop assembly by eliminating a separate component and the fittings that would connect it, while the aluminum housing around the pump motor dampens vibration and mechanical noise. Anti-vibration mounting brackets further isolate the unit from the case chassis. With three G 1/4" threaded ports, the PR22-D5 offers flexibility in how you route your loop, and the heat-resistant acrylic tank stands up to the thermal demands of sustained operation. For builders who want a clean, consolidated pump-reservoir solution without sacrificing D5-level performance, this combo kit delivers.
