109 AXIAL SPRING SEALS: CONICAL Shaft Rotary part Stationary part Total length mm d 3 d 4 I 3 d 6 d 7 I 4 I 5 I 6 I 1 CHARACTERISTICS: • Unbalanced. • Single conical spring. • Dependent on the rotation direction. OPERATING LIMITS: d 1 = 10 ÷ 40 mm p= 10 kg/cm ² v= 20 m/s t= -20÷ +180oC ( *) ( * ) 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: An all-purpose mechanical seal. A single seal with a versatile design that can be used in applications with low demands: for pumping indus- trial wastewater and for household use. Seal compliant with standard EN 12756 (NU). Dimensions subject to changes or modifications.
