What type of mechanical seal is appropriate for my application?

Grundfos industrial pumps can be equipped with a wide variety of mechanical seals. By default, a mechanical seal suitable for typical water applications and for the pumping of certain chemicals is provided. However, some special applications require other materials for the sealing faces or the O-rings or expansion bellows than those used in the standard mechanical seal. For this reason, Grundfos offers numerous mechanical seals with different material pairings for the sliding surfaces.

Mechanical seals are selected on the basis of numerous factors such as pressure, temperature, chemical resistance, the presence of abrasive components and the viscosity of the pumped medium. If you need support in selecting the appropriate mechanical seal for a particular application, please contact your nearest Grundfos-approved dealer of industrial pumps.
