KETO K-IBA™ bearing assembly and K-ISS™ seal upgrades
A copper mine in Tasmania was experiencing frequent and expensive pump failures.
Pumps on this site are located 2.4km underground which means maintenance can be expensive and difficult. The pumps operate at a high speed to develop the high pressures levels required to dewater the mine.
This site was experiencing regular pump failures with the legacy W-W 4/3DD-AH pumps. Bearing barrels were running at extremely hot temperatures at an average of 105°C and had a short life of only 2 to 3 months. Excessive greasing was used in an effort to try to reduce the temperature, potentially compounding the problem.
Additionally, the pumps were consuming excessive quantities of fresh water to lubricate the gland packing, at approx. 30L/min per pump.
