A submersible slurry pump has demonstrated its competitive advantage over other products, thanks to the benefits of an innovative cooling jacket positioned between the outer casing and motor.

Integrated Pump Technology asserts that its Grindex Bravo 600 submersible slurry pump, offers superior reliability and efficiency.

“Mines have a frequent requirement for a hard-working pump to transfer slurry from process tanks, where levels change quickly and the material often becomes quite viscous,” says Marsh. “In these dry-bed applications, many pumps struggle with the density or even burn out when no longer submerged,” says company sales manager Jordan Marsh.

The Grindex Bravo 600 is said to be ideal for these applications, being supplied in South Africa as standard with a glycol-filled cooling jacket to keep its temperature down, designed to allow it to function reliably even when exposed above the slurry level.

“Plant operators are not always able to be present to check the levels in these tanks, or to add water to dilute slurry, so the specific gravity of the material can rise considerably,” explains Marsh. “This is where the Grindex Bravo 600’s agitator comes into its own, agitating the solids into suspension for easier removal. It even handles particle sizes up to 40 mm.”

To demonstrate the pump’s performance under these arduous conditions, Integrated Pump Rental offers mines a trial unit to run over an extended period. Both the impeller and casing are manufactured from hard iron, to further enhance the product’s robust nature and long working life.

“This 22 kW pump also punches above its weight in terms of output, achieving the same performance as our competitors’ 30 kW pumps,” he says. “This makes the solution energy efficient, saving mines on electricity costs.”

In addition, the company offers a 30-month warranty on the units and its Johannesburg-based engineering facility undertakes maintenance and repairs to original-equipment manufacturer standards.
