Spring mechanical seal eHJ

for pumpmetalsteel

For unstepped shafts Single seal Balanced Independent of direction of rotation Encapsulated rotating spring Advantages Especially designed for solids containing and highly viscous media Springs are protected from the product Rugged and reliable design No damage of the shaft by dynamically loaded O-Ring Universal application Variants for sterile operation available Increased axial movement DiamondFace coating possible Spring protection and vibration damping Insensitive to temperature changes 100 % compatible to HJ9... for l1k Operating range Shaft diameter: d1 = 18 ... 100 mm (0.71" ... 4") Pressure: Sliding velocity: vg = 20 m/s (66 ft/s) Axial movement: d1 = 18 ... 25 mm: ±0,5 mm d1 = 28 ... 55 mm: ±0,8 mm d1 = 60 ... 100 mm: ±1,0 mm * An integral stationary seat lock is not needed within the permissible low pressure range. For prolonged operation under vacuum it is necessary to arrange for quenching on the atmospheric side.
