Cartridges & Mechanical Seals

91 MULTISPRING SEALS CHARACTERISTICS: • Unbalanced. • System attached to the shaft by allen screws. • Not dependent on the rotation direction. OPERATING LIMITS: d 1 = 18 ÷ 100 mm p= 10 kg/cm ² v= 20 m/s t= -15÷ +200oC ( *) ( * ) The temperature resistance depends on the material of the secondary seals used. The operating limits are defined by the PV factor which is determined for the sealing system characteristics and those of the application. DESCRIPTION: The contact surface of the rotating part can be de- tached, which makes this model extremely versatile as it is easy to exchange contact surfaces made of different materials. Seal compliant with standard EN 12756.
