OPERATING LIMITS: d,= 25 - 63 mm p= 20 kg/cm! v= 20 m/s t= -15- +200°C (*) (*) 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 cartridge seal with a “tandem” arrangement suitable for working with pressurised or non-pressurised barrier fluids. The metal bellows design has a self-cleaning effect that prevents particles from building up inside it. This model is recommended in extremely demanding applications: with high-viscosity fluids, sticky fluids, particle-laden fluids, fluids with few lubricating and/ or pollutant properties and in high temperature applications. Highly reliable cartridge. CONNECTIONS: From 25 mm to 65 mm: 1/4” NPT. From 70 mm to 85 mm: 3/8” NPT. Dimensions in inches I Shaft" Dimensions subject to changes or modifications. SAFE INDUSTRY
