What Are The Best Pumps For The Mining Industry?
As a Quarry Manager in the mining industry, you understand the importance of efficiency, cost savings, and, above all, safety. Pumps play a mission-critical role in mining operations, whether it's preventing flooding from groundwater or facilitating various mining processes. To help you make informed decisions and achieve your goals, let's explore the best pumps for the mining industry.
Centrifugal pumps are widely used in mining due to their ability to handle large volumes of fluids and abrasive slurries efficiently. They are particularly suitable for mine dewatering purposes and slurry transfer. Designed with robust construction and materials, centrifugal slurry pumps can handle viscous slurries containing abrasive solids like rock fragments and grit. The best centrifugal slurry pumps are energy efficient, providing reliable performance and ease of service to minimise downtime.
Submersible pumps don’t need to be primed, as their inlet naturally ‘floods’, keeping them ready for operation whenever needed. This makes them ideal for situations where the pump may need to start and stop frequently. These electrically driven pumps are sealed against water ingress, making them highly reliable in mine dewatering and tunnel drainage tasks. Submersible pumps can also be used to feed larger high-head centrifugal pumps, enhancing their versatility.
Mining operations often require high-pressure water for mineral ore processing or pumping to higher elevations. Multistage pumps are specifically designed for these demanding applications. By employing multiple impellers arranged in series, these pumps generate the necessary pressure. They find utility in various mining processes, including dust-misting cannons, filter presses, hydraulic mining, and water jet cutting. Single-stage pumps can also be employed to dewater mines by extending the system with an additional pump and holding tank, offering flexibility and process water supply at different intervals within the mine.
Although not as efficient as other pump types, piston pumps, also known as reciprocating pumps, are still used in certain high-pressure mining applications. They can handle heavy-duty tasks, including pumping thick sludges, viscous fluids, and pumping at high heads. These pumps have a long-standing history in mine dewatering and continue to serve specific purposes in the mining industry.
When it comes to transferring thick sludge and solids-bearing slurry steadily, peristaltic pumps, also known as hose pumps, excel. Their self-priming nature makes them ideal for situations where the fluid supply might occasionally run dry. With a seal-less design and only the easily replaceable hose coming into contact with the fluid, peristaltic pumps are reliable and easy to service.
Handling corrosive or hazardous fluids is a common challenge in mining operations. Diaphragm pumps, or Air-Operated Double-Diaphragm pumps (AODD), provide an effective solution. These pumps utilise a flexible diaphragm made from abrasion and chemical-resistant material to displace the fluid. What makes them particularly suitable for mining is their ability to be powered by compressed air, ensuring safe operation in potentially explosive environments where methane gas may be present.

Electrically driven pumps are used for mining as these operate cleanly with no on-site emissions, nor do they consume oxygen as diesel pumps do. In explosive atmospheres, ATEX-certified pumps are used.
In conclusion, choosing the right pump for mining operations is crucial to ensure efficiency, cost savings, and, most importantly, safety. Centrifugal pumps, submersible pumps, multi-stage pumps, piston pumps, peristaltic pumps, and diaphragm pumps each offer unique advantages in different mining applications. By selecting pumps that align with your specific needs, you can optimise productivity, reduce downtime, and enhance the overall performance of your mining operations.
