A gold mine in Argentina has pumps that handle handling mineral pulp with cyanurate solution for gold extraction. The pumps were packed with standard packing and had constant leaks. This required repacking every two-to-three weeks. The customer was looking to increase the mean time between failure (MTBF) and reduce his maintenance costs.

The pump had constant leaks

The pump needed a packing upgrade.



DualPac® 2211 Packing was installed. A test scheme was implemented in two pairs of pumps, making improvements in the installation, settlement and washing for better sealing.

In addition, a training course was offered for the installation of packing. The customer was trained on the relaxation of packing and how to monitor and retighten the gland follower. Improvements were made in the flush water supply by recommending new flush water piping to improve the quality of the flush water.
