Contact SupplierThe HEGLF‑3 is a single‑end, balanced mechanical seal, designed for use in centrifugal pumps—particularly Grundfos CR/CRI/CRN series and similar models. It’s commonly supplied as a semi‑cartridge or flange cartridge seal for easy installation and reliable performance in water, oil, sewage, and mildly corrosive fluids
Fluids: Effective with clean water, sewage water, oils, and moderately corrosive media—thanks to durable face and elastomer selection
Chemical Resistance: Dependent on elastomer choice—EPDM resists acids and alkalis; Viton/NBR provide broad chemical compatibility
