The customer, whose mine is located in Zimbabwe, plays a pivotal role in the mining industry. Their existing mill discharge pump suffered from high wear rates in its wet-end components, and lacked technical support and spare parts availability, resulting in frequent stoppages. These operational hurdles increased overhead costs, negatively impacted plant availability and limited overall production efficiency. Metso recognized this as an opportunity to enhance the customer’s gold production process.
Metso’s experts proposed the customer a solution to introduce the new MDR250 pump, specifically designed for mill discharge applications. The ongoing trial period for the pump spans for six months, with the end date set for October 2024. The pump offers a remarkable 6-month lifespan for wet-end parts, significantly reducing the need for replacements. Operating at a lower pump speed (595 rpm), it is able to achieve the required cyclone pressure while minimizing energy consumption. Special tools, including an inlet door, an impeller lifter and a shaft handler, help facilitate safe and efficient maintenance. Achieving a flowrate of 650 m³/h with a Total Dynamic Head of 33 m and cyclone feed pressure of 0.5 bar at a lower pump speed has showcased Metso’s industry expertise.
