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 heavy duty slurry pumps in Jacksonville, FL can hydrotransport solid materials efficiently, and the long-term benefits outweigh initial costs.
The 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.
Slurry pump installations
Three types of slurry installations exist:
In this installation, the slurry pump and drive are fully submersible. This is necessary for certain slurry pump applications, such as underwater operations.
In this installation, the pump drive and bearings are kept out of the slurry. The wet end which includes the shell, impeller, hub or suction liner, and shaft sleeve or stuffing box is free-standing and clear of any surrounding liquid. Slurry pump technicians install most horizontal pumps this way.
This special arrangement is used for dredging applications with horizontal pumps. Operators flood the wet end and bearings but keep the drive dry. Bearings require special sealing arrangements in this case. Although this guide provides an overview of slurry pumps and their installations, there’s plenty more to learn.
