Bellows mechanical seal eMG®1

for pumpmetalsteel

For plain shafts Single and dual seal Elastomer bellows rotating Balanced Independent of direction of rotation Advantages 100 % compatible with MG1 Small outer diameter of bellows support (dbmin) enables direct retaining ring support, or smaller spacer rings Optimal alignment characteristic through self-cleaning of disk/shaft Improved centering across entire pressure operating range No torsion on bellows Shaft protection over entire seal length Protection of seal face during installation due to special bellows design Insensitive to shaft deflections due to large axial movement ability Suitable for low-end sterile applications Operating range Shaft diameter: d1 = 14 … 110 mm (0.55" ... 4.33") Sliding velocity: vg = 10 m/s (33 ft/s) Admissible axial movement: ±2.0 mm (±0.08") Materials Seal face: Carbon graphite antimony impregnated (A), Carbon graphite resin impregnated (B), Silicon carbide (eSiC-Q7) Seat: Silicon carbide (eSic-Q7, Q1) Elastomer: NBR (P), EPDM (E), FKM (V), HNBR (X4) Metal parts: CrNiMo steel (G), Hastelloy® (M) Standards and approvals Various material approvals available (depending on type and material combinations).
