In 1997 three Wirth™ TPM pumps were delivered to Codelco’s Andina Mine. At the “Overjeria Tailings Dam” they transport tailings 4,000 m above sea level over a distance of 57 km. Each pump is operating with a discharge flow of 140 m³/h and a max. working pressure of 4.0 MPa. A similar application was installed in 1990 at El Soldado Mine with more than 120,000 hours operation without any unplanned downtime.
