Fluiten Mechanical Seals used on horizontal or vertical centrifugal pumps in chemical plants are the result of over 60 years of experience. Standard UNI-EN12756 (ex DIN24960), various models are available in different versions of materials that are selected according to the specific operating condition. The double configuration, equipped with auxiliary lubrication tank, eliminates emissions into the atmosphere and allows to operate with abrasive, toxic or very viscous products. The cartridge solution, with dimensions suitable for different types of case-seal, allows versatility of use, interchangeability and reduction of operating costs.
