Mechanical Seals

If very high demands are placed on the shaft seal, mechanical seals of various manufacturers and designs can be provided. Due to their design and special application conditions, pumps of product groups D, E and CS are generally equipped with single-acting or double-acting mechanical seals.

Practically free of leaks
Maintenance-free
Low-wear
Highly resistant to pressure and vacuum
Safe, ecologically sound sealing when hazardous material is involved.
