Since 2002, four Wirth™ TPK pumps are operating at the Antamina copper mine located at an elevation of 4,200 m. They transport copper concentrate through a 300-km-long pipeline, running from the mine site to the port of Huarmey, north of Lima. Each pump has a capacity of 132 m³/h; the required discharge pressure is 25.2 MPa, while the installed power is 1,300 kW with variable frequency drives being used.
