MECHANICAL SEALS FOR THE MINING INDUSTRY
Mining and minerals
OVERVIEW
Which technology is the best fit for your mining application?
Mines are complex operations that use large volumes of water and harsh chemicals across a wide range of processes.
Pumps are used to move liquids through the production process and drain underground water. Compressors transport gases and air, conveyors move crushed ore and autoclaves, and agitators support the processing and breakdown of minerals. Across all these different applications, reliable mining equipment seals play a critical role in maintaining operational efficiency.
Choosing the right mining sealing, packing, couplings, filtration or bearing isolator technology is essential for maximising the performance and reliability of each type of equipment.
John Crane offers a broad portfolio of solutions for the mining industry, designed to support pumps, compressors and other rotating equipment used in a mine.
