Which product is the best fit for your mining application?

Mines are complex operations that use large amounts of water and harsh chemicals in a variety of methods. They use pumps to move liquids through the production process and drain underground water, compressors to carry gases and air, conveyors for transporting crushed ore, as well as autoclaves and agitators for the processing and breakdown of minerals. With all these different applications, choosing the right product is essential for maximizing the performance of each type of equipment. John Crane offers multiple products for each piece of equipment used in a mine.

Packing is often preferred by pump OEMs and mine operators. Upgrading to mechanical seals can meet the economic and environmental issues mine operators face. Designed for harsh environments, the advanced materials and robust components of mechanical seals are constructed to help lower maintenance costs and improve pump mean time between repair while reducing water and energy consumption. These benefits can be extended through the addition of seal face technologies such as Upstream Pumping or John Crane Diamond®.
