Grindex, a world leader of submersible drainage and sludge pumps, completes its line 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 130 litre/sec. Typical applications include dredging, cleaning of settling ponds, bentonite, coal washing water, sewage treatment plants, steel works, quarries, mines, tunnels 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 4-10. The specially designed impeller creates a strong vortex in the pumped media that carries most of the solids/abrasives through the pump housing. This minimises the wear on the impeller.
