I ran two different dredge pumps on the same job and the results were night and day
Last month on the Clearwater River project, we had to swap out our main pump for a spare when the impeller went. The spare was an older model with a straight suction design, while our main one has a vortex chamber. We ran the old pump for two days. It kept clogging on woody debris every few hours, dropping our yardage by about 30%. Switched back to the vortex pump as soon as we could, and it just chewed through everything without a hiccup. The difference in downtime was huge. Has anyone else found the vortex design that much better for river work?

Sounds like that old pump was basically a fancy clog waiting to happen.

Our old one had a half inch intake line but the filter screen was maybe a quarter inch mesh. How did they think that was a good idea? You could practically hear it struggling with anything bigger than a grain of sand. Was that just the standard design back then, to save a few cents on parts? It feels like they built in a guaranteed failure point from the start.
