Boosting efficiency and cutting costs: Flowrox hose pump success in an African copper mine

Nov 16, 2025

Valmet's Flowrox™ peristaltic pump proved to be a game-changer for the African copper mine facing costly downtime and maintenance challenges. By improving operational reliability and reducing maintenance needs, the mine achieved significant gains in efficiency and profitability. This article highlights our commitment to providing high-performance solutions that create measurable value for our customers.

Customer challenge

An African copper mine was experiencing significant production downtime due to frequent hose replacements in their existing peristaltic slurry pumps. These interruptions not only disrupted daily operations but also led to substantial financial losses from reduced throughput and increased maintenance labor.

Optimized pumping solution for demanding slurry

Flowrox hose pumps are capable to pump 24/7 without overheating at high continuous flow rates due to the roller design that minimizes friction and heat.

Valmet stepped in with a game-changing solution. Our pumping experts analyzed the mine’s requirements and proposed a trial of the Flowrox 360-degree, DN100 peristaltic hose pump. Engineered for demanding slurry applications, this pump is designed to operate continuously without overheating, eliminating the need for a standby pump and drastically reducing maintenance time and complexity.

The previous competitor’s pump was a DN150, whereas the Flowrox pump is a DN100 while delivering a higher flow rate. This improvement not only enhances energy efficiency but also reduces overall system costs. The smaller pump size lowers equipment expenses and allows smaller-diameter piping in new installations, creating additional savings on materials and installation.

Successful trial and superior performance

After a thorough evaluation by our pumping experts, the mine committed to a 60-day trial of the Flowrox hose pump. The results spoke for themselves: the pump delivered exceptional efficiency and reliability, operating flawlessly around the clock. This not only minimized unplanned downtime but also clearly demonstrated the value of investing in robust and high performance technology.

The Flowrox hose pump design allows pumping slurries with up to 80% solids content.

Demonstrated efficiency and reduced operating costs

The results were impressive. The Flowrox slurry pump not only met but exceeded expectations. It offered a hose lifetime of 1000 hours, reduced hose replacement time to just 1 - 2 hours, and required 77% less lubricant. These improvements led to enhanced productivity, lower operating costs, and greater confidence in long-term performance.

Why selecting the right wear-resistant valves and pumps is crucial for ensuring operational efficiency?

The importance of advanced peristaltic pumps

There are two methods to make pumps last longer in abrasive mining operations. One is to harden internal metal components to survive longer than softer metals. The second way is to utilize rubber, which is softer. Sharp or abrasive minerals bounce off elastic rubber surfaces with little damage.

Pumping 76% rock solids with Flowrox™ hose pumps

LKAB Svappavaara iron ore mine in Sweden chose Flowrox LPP-T100 transfer pumps for their pelletizing plant. They were looking for a solution that would allow them to pump effectively paste and high-density slurries. "The most important thing in terms of pump performance is that they function reliably. All the other benefits come after that. If a pump is not reliable, there is nothing else to benefit from either", the customer states.

What makes single rolling design peristaltic pumps the best solution when pumping abrasive slurries?

The superintendent of the water treatment plant was examining shoe designed peristaltic pumps and single rolling design peristaltic pumps. The customer was convinced that Flowrox's peristaltic pump with only one compression per 360 degree revolution will lead to at least 3-5 times longer hose life time than conventional hose pumps. After installation, the first hoses in the Flowrox pumps lasted approximately for 9 months - a great result with 11 million revolutions while pumping abrasive lime.

Flowrox™ LPP-T transfer pumps

Flowrox LPP-T peristaltic pumps incorporate advanced single roller design which eliminates friction and lowers energy consumption. They are ideal for pumping various slurries and dosing a wide range of abrasive, corrosive, viscous or crystallizing media.
