Slurry Pump

Slurry pumps are heavy and robust centrifugal pumps capable of handling tough and abrasive duties. Tobee's comprehensive slurry pump offering covers horizontal pumps, vertical pumps and submersible pumps.

Horizontal slurry pumps are applied in various slurry transport applications. With wear parts in either hard metal or elastomer, horizontal slurry pumps are often larger, more powerful and offer higher capacity than vertical slurry pumps and submersible slurry pumps. Tobee's range of horizontal pumps covers mill discharge pumps, general slurry pumps, and dredge pumps.

Slurry pump is for transporting a fluid handled containing highly abrasive solids such as flotations, suspensions of slag, coal or ore in mining and sinter sludges, or in sand and gravel extraction. Centrifugal slurry pumps are particularly heavily exposed to erosive wear. They are therefore designed in such a way that their wetted surfaces are hard-faced by deposit welding and the components exposed to wear such as rings, bushes, discs, casing inserts, impellers and all types of linings, can easily be replaced by new ones. Slurry pumps must therefore be reasonably inexpensive and consist of materials which are particularly resistant to abrasion or a combination of abrasion and corrosion.

Selection of slurry pump considerations:

Slurry Pump Impeller type – A recessed impeller type can be used, the design minimises contact between the particles and the impeller thereby minimising wear on the impeller whilst being gentle on the particles. Open impeller types can be used, as they are generally easier to clean and maintain. Closed impellers are often regarded as having the best efficiency but can be difficult to clean. The thickness should have suitable wear allowance. You should also consider any impact caused by the required impeller speed.

Casing of Slurry Pump– Metal casings can be used. These may be lined with rubber for added protection or as a sacrificial wear part. Split casings can also be considered, but these can be expensive. The thickness should have suitable wear allowance.

Clearances – Slurry centrifugal pumps should have larger clearances than pure liquid pumps, to allow solids to pass through but also to reduce the velocity within the pump, thereby minimising wear.

These are just some of the things to consider when selecting a centrifugal pump for a slurry duty. In direct liaison with Tobee pump, the professional technical engineer must choose the best options for your pumpingsystem. We will also consider any impact on the shaft and seals, and ensure there will be no issues with cavitation.
