We run a pretty hard die casting operation and need something that ain't gonna quit on us after a few months. How's this pump hold up over time?

Cast iron construction with Buna-N seals gives this pump solid durability in demanding production environments. Die casting is actually one of the specific applications it was built for, so it's not a stretch to say it handles that kind of load. The 4520VQ series design is built around high-pressure, high-speed conditions, and outstanding volumetric efficiency is one of its core strengths, which means less internal slip and more consistent output over the long haul.
