“Slurry pumps need to be up to the task of handling high volumes of abrasive material, and when this is not the case these failures lead to costly production downtime with obvious knock-on effects,” says Adams. “For a number of years, we have been cautioning the market and urging mine operators to carefully consider the overall total cost of operating slurry pumps when making decisions about which units to install.”

Grindex slurry pump Integrated Pump TechnologyIntegrated Pump Technology is the authorised distributor for Grindex submersible pumps. The company often receives enquiries from African-based mining operations who have already made the mistake of not specifying high quality OEM products.

Commenting on why a submersible slurry pump is a better option for slurry pumping, Adams says that submersibles offer several benefits over dry-mounted pumps. They do not require any support structure, need less space for operation and are very easy to install, he adds.

“The Grindex Bravo range are produced to operate over the complete pump curve, not just one specific duty point. This means that the pump can be used in numerous applications within its range and it is not a case of ‘one pump – one application’.”

Grindex Bravo pumps are fitted with a cooling jacket and an agitator for effective slurry pumping. Pumps in the range can handle slurry and fluids with a high content of highly abrasive solids in sizes up to 50 mm at maximum heads from 17 to 45 m. Wear is reduced by using NiHard 4 for all hydraulic components, and these pumps can handle liquids with pH values from 4 up to 10.

Included in its product lineup is the well-respected Grindex Bravo range, which Adams believes offers a good return on investment as the units are engineered to achieve lower operating and maintenance costs.
