Professor V is back. Our resident "Pump Doctor" returns with another dose of pump know-how. This time, he’s tackling lobe wear caused by heavy solids.
Ever heard of solids recirculation in rotary lobe pumps?
That’s where Vogelsang’s injection housing design comes in, as explained in this video.
The injection housing design provides a controlled flow of liquid directly into the throat of the lobes, eliminating suction side recirculation, reducing friction, flushing out troublesome media, and keeping your lobes protected. It’s a simple idea with big payoffs: less downtime, fewer service calls, and extended pump life.
Professor V breaks it all down in this video: why it matters, how it works, and how Vogelsang’s design keeps your operation moving smoothly. Because at the end of the day, details matter.
