It is critical to determine the right slurry pump size and power requirements for your application. Depending on the abrasive nature of the slurry, it is important to select a pump size that will allow it to run at a slow enough speed to extend the life of the slurry pump. The ideal RPM to run a slurry pump is between 900 and 1200 RPM. Once that speed is started to be exceeded, the life of the pump is greatly reduced because the wear points of the slurry pump are actually sandblasted.

One problem with centrifugal pumps is that the velocity and shear forces within the pump may damage the slurry/solids. Typically, twin-screw pumps cause the least damage to solids in the slurry.

How to Choose a Dredging Pump or Slurry Pump

To reduce wear, reduce the pump discharge pressure to the lowest possible point.

As described below, there are several , types of pumps, that are suitable for pumping slurries. However, before considering which technology to use, we must address several key issues.
