Grindex has updated its Bravo series of slurry pumps to make them tougher and include 45 W and 70 kW versions.
The BRAVO submersible electric pumps are designed for use in mines, quarries, dredging and construction operations that require the transfer of abrasive particles such as stone, steel or bentonite.
They are also suitable for use in industries that need to move various kinds of slag products such as coal and ore slurry, or when dredging and cleaning sediment ponds.
The hydraulic parts of the Bravo 400-900 are now made from Hard-Iron, a high chromium cast iron which is at least four times harder than standard cast iron.
The new pumps are fitted with 4-pole low revolution motors from 4.7 KW up to 70 KW, which enable large amounts of slurry with very high particle content to be pumped quickly and effectively. The pumps are also fitted with an agitator beneath the pump intake, which functions as a propeller and creates a downward stream that stirs up the material prior to pumping.
The range now has a new cooling jacket for dry pit usage, widening its range of possible applications. In total the Bravo series comprises eight pumps with capacities ranging from 30 to 130 litres per second.
The new generation Bravo pumps have interchangeable parts, cutting down on both storage and maintenance costs.
