Laing / Xylem: Trusted Pump Technology Behind the Best Loops

Laing, now part of global water technology leader Xylem, has long been at the heart of high-performance PC watercooling. Known across the industry for their D5 and DDC pumps, Laing has set the standard for reliable, high-flow, and low-noise pump designs. These pumps have powered countless custom loops, offering the perfect balance of pressure and durability for everything from compact SFF builds to high-end multi-GPU workstations.

Over the years, the Laing name has operated under several brands, including Lowara and now FloJet, but the engineering behind their pumps has remained consistent. The D5 pump is renowned for its quiet operation, smooth flow, and extended lifespan, while the smaller DDC pump is prized for its compact footprint and strong head pressure, ideal for tighter or more complex loops.

Whether branded as Laing, Lowara, or FloJet, these pumps remain the gold standard in the custom cooling world. Backed by Xylem’s global reach and manufacturing excellence, they continue to be the trusted choice for builders who care about long-term reliability and consistent cooling performance.
