Cartridges & Mechanical Seals

90 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= 16 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: Double seal for working with barrier fluids in which the springs are isolated from the fluid product. API 53A and API54 assemblies. Recommended in applications with toxic, pollutant or potentially dangerous products in which safety is an important factor. Available with a pumping ring on the casing to reduce the temperature between the contact surfaces and facilitate the barrier fluid move- ment (reference LMS10D-F). Available in a balanced version with a stepped shaft (reference LM10BD). Contact surface kits available.
