Question by: Stan W on Sep 21, 2025, 11:39 AM
Got a press machine running hard most of the day, would this pump hold up under that kind of continuous load?
Answer by: Customer Support on Sep 22, 2025, 2:11 PM
Cast iron construction and the internal geometry on these VQ series pumps are built to take extended, continuous duty without breaking down early. Press machine applications are actually one of the listed uses for this pump, so it fits right in that kind of environment. The flow rate comes in just under 309 litres per minute, which gives you solid output even when the system is pushing hard for long stretches.
