What is a dry-running pump?
In a dry-running pump, the component that comes into contact with the medium (the wetted part) is separate from the motor. The seal of the pump shaft in the wetted part is provided in the form of a mechanical seal. The pump is driven by a motor connected to the pump shaft by a coupling.
What is a wet-running pump?

What type of mechanical seal is appropriate for my industrial 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.
