Industry Insights - Seawater Engine Cooling Impeller


This week at the DF Barnes Machine Shop, our team delivered a custom solution to a tough marine challenge — reverse engineering a critical seawater engine cooling impeller that was no longer available on the market.

Crafted from a solid 7-inch bronze billet on our state-of-the-art HAAS-1600 5-axis CNC machine, this impeller is built to perform in the harshest marine environments. Precision-engineered and purpose-built, it’s a perfect example of how we turn breakdowns into breakthroughs.

At DF Barnes, we combine advanced machining with deep industry experience to deliver tailored solutions that keep our customers moving forward — no matter the obstacle.

When off-the-shelf isn’t an option, innovation steps in.
