How to Choose a Dredging Pump or Slurry Pump

The design of the slurry pump is critical to ensure that the abrasive and often corrosive aspects of the slurry do not damage the impeller. In addition, slurries and sludges may contain large amounts of unforeseen solids, which will inevitably clog many types of pumps. Since most centrifugal pump impellers have very tight tolerances on the worm gear, the abrasive (and sometimes corrosive) nature of the slurry will quickly wear down the worm gear and destroy the tolerances. In turn, this causes the pump to lose suction. This can lead to extensive downtime of the slurry pump, as well as expensive maintenance and spare parts.

How Slurry Pumps Differ From Standard Pumps?

Slurry pumps can be used to transport mixtures of liquids and solids in many industries in a wide range of applications, such as mine drainage, dredging of sunken lagoons and pumping of drilling mud.

Positive displacement slurry pumps with limited capacity to deliver high head are used to pump slurry through pipes with very high solids concentrations.
