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.

Examples of these dubious enhancements to impeller adjustment abound in the industry. One of these is the adjustable wear ring or suction liner to maintain the recommended clearance between the impeller front shroud and the throat bushing face. Almost all >slurry pumps, including AIER® slurry pumps, have features to ensure that this equipment specification can be maintained over time.

The size and nature of the solids in the liquid: The size and nature will affect the amount of physical wear on the pump and its components, and whether the solids will pass through the pump without being damaged.

Hydrostatic head - i.e. the height to which the slurry must be lifted in the piping system.
