FAQ
FAQ Are flanges included within the scope of delivery when ordering circulator pumps or do these need to be ordered separately? Can the pump be operated using a frequency converter? Can the SP pumps also be operated in a horizontal position? Why are the displays on the operating panel lit even though the electrical power supply is switched off? Do I have to follow the instructions for Grundfos pumps? Does the built-in excess temperature protection of the UPS pump need to be used?
