Other manufacturers looking for differentiation, if not the end result, may choose to add a small part to their pump assembly in the description, thus allowing in-line adjustment of the wear ring in the suction side lining assembly.

For pumping abrasive slurries, these types of pumps can also be made from specialised high-wear alloys. Hardened stainless steel is also a common choice for abrasive slurries.

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

As wear is a function of speed, slurry pumps should be operated at the lowest possible speed; units typically run at 1,200 rpm or less. Often, direct coupling between the pump and a low-speed motor or other drive makes the most sense. On the other hand, many other applications favour gearboxes to meet the required speed and operating point. In services where variable flow rates are required, variable frequency drives are used to provide the necessary continuous speed variation.

The impeller is considered the heart of the dredge pump and is similar to a fan that expels air and creates centrifugal suction. At the suction pipe, this vacuum absorbs the slurry and transports the material through the discharge line.
