Determine the perfect combination of slow pumping (to reduce wear) and fast pumping to prevent solids from settling and clogging.

Choosing Dry Slurry Pumps Versus Submersible Slurry Pumps

Process speed doesn’t have anything to do with choosing slurry pump impeller, but it does have an effect on the life of slurry pump impeller. It is important to find the sweet spot that allows the slurry pump to run as slow as possible, but fast enough to keep solids from settling and clogging. If pumping too fast, the slurry can quickly erode the impeller due to its abrasive nature. This is why it is important to select a larger impeller if possible.

Despite the complexity of internal flow patterns, the overall performance of dredge pumps is predictable.

Compared to standard centrifugal pumps, centrifugal pumps optimised for slurry pumping usually have the following features.

Metal and/or rubber pump bushings are used to combat the erosion of solid particles found in the slurry. Metal slurry pump housings are usually made of carbide to resist erosion caused by increased pressure and circulation. Sometimes wear-resistant steel is used on the pump casing so that the pump can be welded if repairs are needed.
