Double Cartex GSDN gas seals are newly developed for refinery and chemical plant centrifugal pumps.
You can install the bidirectional gas-lubricated seals to standardize new pumps or recondition existing models which have conventional stuffing box packings or liquid-lubricated mechanical seals, reports the manufacturer.
HR principle is Cartex GSDN’s characteristic design feature. The seat and shaft sleeve rotate along with pump shaft. Springs remain stationary. Internal pressurization together with centrifugal forces, create a self-cleaning effect at the sliding faces during ongoing operation. This prevents harmful contamination and increases operational reliability — especially in applications where media contain solids.
