Bellows mechanical seal EA560

for pumpmetalsteel

Single seal Loosely inserted seal face provides self-adjusting capability In-house manufactured sliding parts Advantages The EA560 is self-adjusting to shaft misalignments and deflections because of the loosely inserted seal face as well as the ability of the bellows to stretch and tighten. The length of the contact area of the bellows with the shaft is an optimum compromise between ease of assembly (less friction) and sufficient adhesive force for torque transmission. Additionally the seal fulfills very specific leakage requirements. Because the sliding parts are made in-house, a wide variety of special needs can be accommodated. Operating range Shaft diameter: d1 = 8 … 50 mm (0.375" … 2") Sliding velocity: vg = 5 m/s (16 ft/s) Axial movement: ±1.0 mm Materials Seal face: Carbon graphite resin impregnated (B), Silicon carbide (Q1, Q2) Seat: Aluminium oxide (V), Silicon carbide (Q1, Q2) Elastomer: NBR (P), FKM (V) Metal parts: CrNi steel (F) Recommended applications Water and waste water technology Chemical industry Process industry Water and waste water Glycols Oils Industrial pumps/equipment Submersible pumps Engine pumps Circulating pumps
