As the name suggests, the Slurry Pumps are for pumping materials. The key to slurry pump success is the generation of centrifugal force, which pushes material outward from the pump center.
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 hydro transport solid materials efficiently, and the long-term benefits outweigh the initial costs.
According to different usage scenarios, the slurry pump can be divided into three types:
Wet — In this installation, the slurry pump and drive are fully submersible. This is necessary for certain slurry pump applications, such as underwater operations.
Dry — 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.
Semi-dry — 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.
