Pacific PT40 Pump and Tank Unit

The Thermaltake CL-W001-PL00BL-A combines a pump and 400 ml reservoir in a single POM and PMMA body. It is built for DIY liquid-cooling builders who want an integrated unit that reduces tubing runs and simplifies loop planning. The clear acrylic tank lets users monitor coolant level and flow at a glance. It suits compact or custom configurations where space is limited.

Three G 1/4 Thread Ports and Mounting Options

The unit provides three G 1/4 ports for standard fitting connections. It supports both vertical and horizontal mounting using the two included reservoir clamps. A 3-pin extension cable, screws, nuts, velcro pad, zip-ties, a wrench and an Allen tool are supplied for installation. The 247 mm length and 81 mm width define the footprint required in the case.

400 ml Capacity with 500 L/hr Flow

The 400 ml tank holds enough coolant for most small-form-factor loops while leaving headroom for expansion. The pump delivers 500 L/hr, which circulates fluid effectively through CPU and GPU blocks in typical single-loop builds. Very large loops with multiple radiators and long tubing runs may exceed the practical flow headroom of this pump. Builders planning extensive multi-component loops should verify flow requirements before committing.

Questions about this item

How do I choose between a vertical or horizontal mount for the PT40 pump and tank?

Both orientations are supported. Use the two included mounting clamps and the supplied screws, nuts, velcro pad and zip-ties to secure the 247 mm by 81 mm by 65.9 mm unit in the orientation that fits your loop layout.

What does the 500 L/hr pump performance mean for my custom loop?

The 500 L/hr rating is the maximum flow the pump can deliver. Actual flow in your loop will be lower once you add blocks, radiators and tubing, but the figure shows the pump has headroom for typical single-loop builds.

What fittings work with the three G 1/4 thread ports?

Any standard G 1/4 threaded fitting — compression, barbed or rotary — will screw directly into the three ports. The package includes a wrench and an Allen tool to tighten them without damaging the POM and PMMA housing.
