Slurry pumps can withstand extensive wear due to characteristics such as: a large impeller diameter, shafts, bearings, and internal passageways as well as heavy-duty construction. On an industrial level, slurry pump features generate higher upfront and operational costs compared to water pumps. However, only slurry pumps can hydrotransport solid materials efficiently, and the long-term benefits outweigh initial costs.
Key to slurry pump success is the generation of centrifugal force, which pushes material outward from the pump center. This contrasts with centripetal force, which pushes material toward the center. Slurry pumps must operate on centrifugal principles because the forces that impart velocity to the slurry accelerate the transport process. A centripetal pump, on the other hand, would be impractical since the solids within the slurry would accumulate instead of flowing freely.
Knowing these basics, it’s also important for anyone looking to install a slurry pump to understand the specific environments required for each type of pump. Three types of slurry installations exist:
Those with experience pumping slurries know it's not an easy task. Slurries are heavy and difficult to pump. They cause excessive wear on pumps, their components, and are known to clog suction and discharge lines if not moving fast enough.
It’s a challenge to make slurry pumps last for a reasonable amount of time. But, there are a few things you can do to extend the life of your slurry pump and make pumping slurry less of a challenge.
Although this guide provides an overview of slurry pumps and their installations, there’s plenty more to learn. For those who want to better understand slurry pumps and their applications or need help deciding which pump and installation type is best for their applications, KATI is here to help.
