GRUNDFOS : Speed-Controlled Pumps





Grundfos pumps cover a broad range of applications and an even wider variety of configurations. From single-stage to multistage; dry-pit as well as submerged pumps; from clean water to sewage - in cast iron, composite, stainless steel and even titanium, each pump is developed to perform under specific conditions.

We are one of the world’s few pump manufacturers who are responsible for developing and producing every single element of their pumps and associated technology. Electronic components such as control units, frequency converters, motors and sensors are all developed in-house to achieve perfect product and system integration.

This wide range and built in cross-compatibility of components allows us to provide solutions for every application – usually without the need for custom-built solutions and the subsequent cost.
