This type of seal is specially designed cartridge seal for pumps handling slurries, sludges, syrups and other fluids that polymerise or solidify with changes in temperature. The stationary spring in this design are protected from the fluid being sealed by means of dynamic 'o' ring. Surf ace below dynamic 'o' ring is given with the coating of wear resist ant material like stellite, chrome oxide or tungdten carbide. Both mating faces are of extremely high abrasion and wear resistance materral. This is a single seal that replaces double seals in most applications.
