With the high-pressure centrifugal pump "Helix" the pump expert Wilo presented to Chillventa 2010, a highly energy-efficient, durable and maintenance friendly pump for cold water supply and cooling cycles.
By default, the pump series "helix" of IE2 motors, so they already meet the requirements of mid-2011 from current regulation to electric motors under the European Eco-design Directive (also known as ERP / EuP directive).
It would also appear the "Helix" by a particularly efficient, with extremely precise laser welding technology made hydraulics. This allows the development of the higher specific pressure with fewer pumps levels.
Another advantage is high on durability and longevity designed structure. Thus, for example used for the production of impellers and stages with the high-quality stainless steel type 1.4307 or 1.4404, a corrosion-resistant material.
