MG12 Mechanical Seal, G6 Stationary Type | Sealing Tech-G

The MG12 Mechanical Seal with Sealing Tech-G G6 Type Stationary is a single, unbalanced mechanical seal with an elastomer bellows and central spring. Its design is independent of the shaft's direction of rotation, which gives it great versatility for a wide range of rotary applications. The G6 Type stationary (unlike the G60) is specially designed for media containing suspended solids, such as wastewater, sludge, and industrial effluents, thanks to its robust geometry and its ability to handle particles without compromising the seal. Available in shaft diameters from 16 mm to 43 mm, with SiC/SiC or C/SiC faces and EPDM elastomer.

Applications

• Wastewater treatment: sludge pumps, effluent, and water with suspended solids
• Municipal industry: sewage and gray water pumping stations
• Agricultural industry: slurry pumps, leachate, and irrigation water with particles
• Chemical industry: corrosive fluids or those with solids compatible with EPDM
• Food industry: pumps for viscous fluids or those with particles (with SiC/SiC faces)
• Industrial maintenance: seal replacement in centrifugal pumps with metric shafts from 16 to 43 mm

Difference between G6 and G60 Stationary

The G6 Type stationary is optimized for media with suspended solids (wastewater, sludge), while the G60 Type is designed for clean fluids. Correct stationary selection is key to ensuring the seal's service life in each application.
