Question by: Terry A on Jan 22, 2026, 8:41 PM
what all industries is this pump actually used in? got a wood processing line and trying to figure out if this is the right style pump for that kind of setup
Answer by: Customer Support on Jan 24, 2026, 6:59 AM
Wood processing is one of the listed applications for this pump, along with plastics machinery, press machines, die casting, machine tools, test equipment, primary metal processing, pulp and paper, oil and gas, and marine work. The VQ series was built around high-cycle production environments, so it holds up well in the kind of continuous-duty conditions you'd see on a processing line.
