The challenging conditions in slurries require pumps that are robust and reliable, to ensure effective pumping of fluids with high concentrations of abrasives, such as sand and stones.

The abrasive nature of materials leads to high wear and tear on pump components which can lead to high maintenance and repair costs and costly production downtime, while the accumulation of excess sediment can cause further operational difficulties.

Integrated Pump Technology key account manager Justin Bawden says that Grindex Bravo pumps are specifically designed for the demanding task of pumping slurry.

The Bravo range features hydraulic components made from hard iron, to ensure durability and reliability, even in conditions of extreme wear and tear. The pump agitator is designed to efficiently mix and suspend solids, allowing the pump to transport the material effectively.

Bawden says the Grindex Bravo pumps include features that enhance performance and ease of maintenance. The pumps are designed for dry pit applications, thanks to a cooling jacket, reducing the risk of overheating. A ready-to-install cartridge seal minimises downtime during repairs and assembly. The inclusion of a leakage sensor helps prevent further damage, saving on maintenance costs. The large inlet can handle solids of varying sizes, while the hard iron impeller and pump housing help maximise durability and performance. A single adjustment sleeve unit allows for easy impeller adjustment, and the agitator stirs up sand, sludge and solids in suspension.

The range is rugged and versatile, capable of handling liquids with pH values ranging from 5.5 to 14. The 22 kW pump can be fitted with a SMART unit with a built-in plug and pump, eliminating the need for external starter boxes. The pump is further protected by phase-failure guards, temperature guards and phase-sequence control, ensuring safe and efficient operation.

Bawden says that every pumping application is different and that Integrated Pump Technology can help select an appropriate pump unit based on specific parameters.

In addition to durability, the pumps are designed for energy efficiency, enabling long-term savings in energy consumption and making them a cost-effective solution.

Replacement parts are said to be readily available from the company’s head office or through its network of distributors. “This swift access to parts minimises downtime and reduces repair turnaround times, ensuring that pumps are back in action as soon as possible,” Bawden says.

Grindex slurry pumps are recommended for industries such as quarries, mines, dredging and cleaning of settling ponds that require pumps with high durability.
