• Balanced. • Welded metal bellows. • Not dependent on the rotation direction. • Barrier fluid connections. (*) The temperature resistance depends on the mate- rial 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. 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 appli- cations. Highly reliable cartridge. CONNECTIONS (R): From 25 mm to 65 mm: 1/4” NPT. From 70 mm to 85 mm: 3/8” NPT
