Central supply systems for mechanical seals
A central storage tank can supply several mechanicals seals with seal liquid on demand.  Seal supply systems for operating pressures from 200 bar are already in operation. The central supply is of particular interest if large quantities of similar pressure vessels are to be operated simultaneously as is often the case in production units in the chemical industry or in high-pressure autoclaves in minerals processing. Inspections with refilling in place are no longer necessary. This lowers personnel costs in production plant maintenance. The frequency of the automatic refill permits an evaluation of the condition of the wear parts so that wear parts can be ordered on time and preventive maintenance procedures can be planned in advance.

Non-metallic mechanical seal ESD42 for side entry agitator installation
The ESD42 for side entry agitators, which has been used many times worldwide and proven its worth, has been improved in detail in order to even better meet the challenge when confronted with corrosive media. This can be achieved by replacing product-wetted metallic parts with ceramic and polymer components.
Operational safety and increased lifetime are benefits that the plant operator experiences when using side entry installations in strongly corrosive media such as absorber suspensions in flue gas desulfurization plants

Agitator seals with fracture-proof seal rings
The ceramic parts of seal rings used in the chemical and other related industries are often damaged under extreme operating conditions and respectively require increased seal reliability with very critical media. Damage can be caused by extreme operating conditions such as rapid temperature or pressure changes which could finally lead to a total breakdown of the mechanical seal. Fracture-proof seal rings have been developed that can withstand such extremes without any difficulties. Increased lifetimes, and most of all increased plant safety, minimize risks for the plant operator.
