Sterile System
Special requirements for mechanical seals occur in the operation of sterile processes, such as food processing, in the pharmaceutical industry and in the biotechnology. Therefore EKATO offers a complete sterile system consisting of a mechanical seal and a sterile installation.
These sterile systems are used when the vessel / process needs be sealed from any biomass by the mechanical seal.
The EKATO sterile system is an ideal solution for the process demand of a hot and completely sterile seal liquid, where biomass can not grow. On the other hand it serves the mechanical seal demand of cool seal liquid for seal face lubrication and cooling.

Functional description of the sterile system
Step 1: Flow-through sterilization
Cleaning and sterilization of all parts with fresh steam during standstill of the agitator
Step 2: System-filling
Filling the system with sterile condensate during standstill of the agitator
Step 3: Continuous loop-operation
Cyclical sterilization of the condensate by fresh steam and seal liquid condensate cooling by the heat exchanger during operation
Features – sterile system
- Complete sterile system, mechanical seal and sterile installation out one hand (less interfaces)
- Self regulating system with very low energy consumption
- Optimized mechanical seal design without gaps (ESD34S / ESD44S)
- Sterile conditions in the storage vessel during operation: no microbe growth
- Constant circulation and continuous sterilization of the condensate
- Overpressurized system due to steam pressure: no entry of extern contaminations
- Sterilization of the condensate after exiting the seal by inflowing fresh steam
- Sealing liquid condensate cooled by plate heat exchanger
- Sealing liquid condensate with ideal operating temperature: extended seal lifetime
