In January 2025, Nord Minerals team successfully completed the pilot testing of a new gravel series pumping equipment with an increased flow section for a metallurgical industry customer in Kazakhstan.
During a CTS shop inspection of the customer’s pump fleet, Nord Minerals experts noticed that four 8c8 series recirculation pumps were not performing well. They could not withstand handling abrasive material – ferrosilicon magnetite. Flow paths, seal and bearing units failed every 2-3 months, and the customer had to purchase two additional pumps and 48 sets of spare parts each year.
To eliminate this problem, Nord Minerals developed a more cost-effective and efficient technological solution. An 8/6 ROITECH pump with a frequency converter was installed in place of the worn-out pumps. The new equipment was equipped with spare units and a flow path designed for increased wear resistance.
Additionally, Nord Minerals specialists have solved the following tasks:
During five months of testing, the pump has demonstrated stability and reliability:
The successful testing has become the basis for ling-term cooperation: the modernization of the remaining three slurry pumps is already scheduled for this year.
