Meet the expert: CR Air-Cooled Top pump

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.

Solutions for buildings

The world’s increasing urbanisation is contributing to significant amounts of energy being used. The global cooling demand alone has doubled in less than 20 years. And water and energy go hand in hand. In general water pumps currently account for a huge amount of the world’s electricity consumption — but with more energy efficient pump solutions, this amount can be heavily reduced.
