Heavy-duty mechanical seals from Meccanotecnica Umbra are engineered to survive the punishing conditions of mining and mineral processing. Our solutions address the extreme abrasion, high solids content, and aggressive slurry environments found in grinding mills, hydrocyclone feed pumps, flotation cells, and tailings transfer systems.
Tungsten carbide and reaction-bonded SiC seal faces rated for high-solids slurry applications.
Robust cartridge designs with oversized cross-sections to withstand shock loads and shaft deflection.
Seal face pairings tolerant of intermittent dry-running conditions during process upsets.
Integrated quench arrangements preventing abrasive particle ingress into the seal chamber.
