Meet Professor Vogelsang, aka the "Pump Doctor." He's here to bring you thought nuggets on technology, application insights, and other musings. In this video, he provides a quick breakdown on adjustable housings for Vogelsang VX rotary lobe pumps. This feature saves you money on lobes, by allowing you to adjust the housing segments of a pump to compensate for wear.
In rotary lobe pumps, performance really comes down to having the slightest of gaps between the lobes and the housing. But as those lobes wear down over time, that tiny gap gets a bit bigger — and the pump doesn’t work quite as well.
Most pumps try to make up for it by cranking up the speed, but let’s be honest: that’s just a temporary fix. Sooner or later, you’re stuck replacing the lobes.
Here’s where Vogelsang brings the magic: Its adjustable housing lets you easily tweak the pump by lowering the housing segment and tightening that gap back up. Just like that, your pump’s performance is back to almost factory-fresh, and you didn’t even have to touch the lobes.
Even better? You’ve got three adjustment settings to play with, meaning you can do this quick fix twice before it’s finally time for a lobe swap. That’s longer service intervals and way less hassle.
