OPERATING LIMITS: d,= 25 - 140 mm p= 20 kg/cm! v= 25 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-pressu-rised barrier fluids. Recommended in applications in which a high level of safety is required. Possibility of incorporating a pumping ring to reduce the temperature gradient between the mechanical seal contact surfaces. CONNECTIONS: From 25 mm to 60 mm: 1/4” NPT. From 63 mm to 110 mm: 3/8” NPT. Dimensions subject to changes or modifications. 07/16 & Hidering SAFE INDUSTRY
