Slurry Pumps handle abrasive applications.
December 2, 2004 - Bravo pumps suit fluids with high concentrations of sand and stones. Available in 5 sizes, pumps deliver between 470–2,000 gpm and handle liquids with pH values from 4–10. Units are equipped with 4-pole low speed motor and hydraulic components are made from Ni-Hard 4. Typical applications include dredging, cleaning of settling ponds, coal and ore slurries, bentonite, coal washing water, sewage treatment plants, steel works, quarries, and mines.

New Submersible Slurry Pump Handles Dredging with Sand and Stones
Grindex new slurry pump series Bravo is designed for very abrasive applications in mines and quarries and alike. Slurry and other fluids with high concentrations of sand and stones normally wear out the hydraulic parts of the pump. Grindex has solved the wear problem by producing hydraulic components in the Bravo pumps in Ni-Hard 4, one of the hardest materials available today. The Bravo pumps can deliver between 470 and 2 000 gallons per minute.
Grindex, a world leader of submersible dewatering and sludge pumps, has completed its program with the new Bravo-series. The Bravo pump is designed for one of the most abrasive tasks, pumping liquids with high concentration of sand and stones. The wear is reduced by choosing Ni-Hard 4 for the hydraulic components. Bravo is available in five different sizes with capacities up to 2,000 gallons per minute.
"At dredging works, for example, the sand and stone in the water wear out a regular pump very quickly. Previously we have been unable to do business with our standard pumps because they can't handle the wear well enough," says Gunnar Benselfelt, Marketing Manager at Grindex.
"The Bravo series completes our pump range and gives us the opportunity to serve new customers," he continues.
Bravo, made for tough environments
Typical applications include dredging, cleaning of settling ponds, coal and ore slurries, bentonite, coal washing water, sewage treatment plants, steel works, quarries, mines and many other industries. All BRAVO pumps are designed for continuous work in demanding environments, where pumps with very high durability are needed. Bravo can handle liquids with pH values from 4 to 10.
The specially designed impeller creates a strong vortex in the pumped media that carries most of the solids/abrasives through the pump housing. This minimizes the wear on the impeller.
The agitator creates a downward jet beam that enhances the efficiency
The pumping is even more efficient due to the agitator. Placed on the impeller, the agitator creates a jet beam downwards that feeds the impeller with high-density material.
Apart from the hard material Ni-Hard 4, the Bravo pumps are also equipped with a powerful 4-pole low speed motor to enable pumping of heavy slurry. The pumps are available in motor sizes from 5 to 40 kW (7 to 54 hp) and can be equipped with different motor protection and surveillances, depending on customers need.
