OPERATING LIMITS: d 1 = 20 ÷ 100 mm p= 12 kg/cm ² v= 15 m/s t= -20÷ +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: Single mechanical seal with an extremely versatile and functional design. The fact that it is attached to the shaft with screws allows this seal to be installed in a large variety of applications with differing mounting dimensions. Its structure allows secondary seals made of diffe- rent materials to be used: FKM, Aflas ® , FFKM, FEP, NBR, HNBR and materials complying with special standards such as FDA, USP, EC, etc.
