Grundfos UPS2 Circulator Pumps Databooklet

High-efficiency circulator pump with permanent-magnet motor (ECM technology) fit for the ErP directive no. 641/2009 due to continuous variable-speed control for circulation of clean heating water according to VDI 2035.

Features and benefits: UPS2 25-80 180

• complies with the requirements of the ErP directive as from 2015
• one pump replaces three variants
• it is available as pump head without pump housing. Fits all 4-m, 5-m and 6-m pump housings of the Series 100
• for tight installations, in, for example, boiler applications
• high energy savings thanks to an energy efficiency index (EEI) lower than 0.23
• complies with the German regulation on energy saving in buildings and building systems – Energieeinsparverordnung – EnEV §14(3)
• one button for simple selection among three proportional-pressure curves or three fixed speeds
• no corrosion issues thanks to the electrocoated pump housing
• reduced installation costs as no external motor protection is required.
