Besides its comprehensive pump and valve programme, the KSB Group also presented its mechanical seal range, now comprising more than 30 type series, at this year’s IFAT trade fair.One of the exhibits in Munich will be the 4EB series. This is a mechanical seal specially developed for large pumps handling drinking water and service water. The single mechanical seal in modular design is very compact.

With the mechanical seal optimally matched to its installation space in the pump, wear is kept to a minimum, ensuring a long service life. 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.

When designing the 4EB seal the engineers attached great importance to straightforward installation and removal. Assembly fixtures and fastening bolts are not required; the seal’s modular design minimises downtime during maintenance inspections and prevents faulty reassembly. The mechanical seal is suitable for a dynamic operating pressure of up to 25 bar and a static operating pressure of up to 37.5 bar.
