Double seal, assembled “face to face”, compact design (cartridge), balanced, depending on the direction of rotation of the shaft (GFR – right, GFL – left), multi-spring. Requires a barrier gas supply.
GF seals are recommended for applications where a particularly high purity product is required. Designed to work with toxic, carcinogenic, explosive (with potential spontaneous combustion) media, process gases, etc. in the chemical, petrochemical, pharmaceutical, metallurgical, coke-chemical and other industries.
– long period of trouble-free operation and between technical inspections,
– absence of emission of harmful substances into the atmosphere, guarantees the sealing of the pump (when the gas pressure decays, GF works in contact mode).
