At this year’s IFAT trade faire, the KSB Group will also be presenting its mechanical seal range, now comprising more than 30 type series.

The 4EB series is a mechanical seal developed for large pumps handling drinking water and service water. The single mechanical seal in modular design is compact. With the mechanical seal matched to its installation space in the pump, wear is kept to a minimum.

Certified for drinking water

The primary rings are made of silicon carbide as standard. For the mating rings the user can choose between silicon carbide and carbon graphite. The O-rings are made of EPDM or FKM elastomers certified for drinking water. All metal components are manufactured from corrosion-resistant stainless steels such as 1.4122 or 1.4571.

A multi-spring arrangement provides the required pre-loading for the mechanical seal without coming into contact with the fluid handled. This protects the individual springs from contamination and leads to a longer overall seal life.
