An Overview of Slurry Pumps

Slurries can be found in many industries including food, dairy, and beverage processing. Slurries have properties that combine liquids and solids. Therefore, it is important to consider the specific requirements when choosing the right size and type of slurry pumps to be used with them.  Depending on your specific needs, you can shop for the right slurry pumps on https://www.schurcoslurry.com/slurry-pumps/.

Slurries are mixtures of solids and liquids. The liquid acts as the transport mechanism to move the solid. The size of the particles (or solids) in slurries ranges from one micron in diameter up to hundreds of millimeters in diameter.  A pump's ability to move a slurry along a process line is greatly affected by the particle size. 

Industries classify slurries into four different classes according to how aggressive they are. Class 1 is the most aggressive, while Class 4 is the least aggressive. Pumping slurries can cause wear to both pipelines and pump components.

Abrasions include gouging, high-stress grinding, and low-stress grinding(only applicable to settling-type drinks). Erosion is the result of the action of particles in the slurry being pumped. The pumping of settling-type fluids is the most common cause of erosion.

Corrosion is caused by the electric galvanic action of the fluid being pumped. Some slurries, such as highly acidic or alkaline compound slurries, will have a greater impact on component corrosion than others.
