Cartex Dual Seals Manufacturers | Seals For Mining Industry

Features

Dual seal
Cartridge
Balanced
Independent of direction of rotation
Double pressure balanced
Integrated pumping device
Variants available: for eccentric screw pumps (-Vario) and gas-lubricated version (-GSDN)

Advantages

Up to 80 % less energy consumption and minimized heat generation of seal due to friction-reducing DiamondFace layer
Up to 100 % extended operating period, prolongation of MTBF and MTBR intervals
Significantly improved dry-run capability for inadequately lubricated sealing surfaces, thus vastly improved process safety
Universally applicable, even with high solids content in the medium

Operating range
