The CR Air-Cooled Top pump from Grundfos – explained

The Grundfos CR Air-Cooled Top multistage, inline pump is for applications that require handling very hot liquids, from 120°C to 180°C (248-356°F). The pump has a special air-cooled shaft seal chamber, ensuring that the liquid temperature around the shaft seal does not exceed the level it can withstand.

Our application manager, Michael Laustsen, guides you through this pump, taking it apart and showing how the Air-Cooled Top functions and why Grundfos designed it that way.
