Pump replacement brings energy savings
Replacing pumps in a 238-bed hospital in Germany has reduced energy consumption by 40 MWh a year following a pump audit carried out by Grundfos Pumps. Salem Hospital in Heidelberg was built in the 1970s, and the audit discovered that the existing pumps were tremendously oversized, which is often the case in older buildings. They were also far less efficient than today’s high-efficiency speed-controlled pumps.
Grundfos explains that even pumps that are only five to 10 years old can be outdated, as modern speed-controlled pumps ensure that flow and pressure are always precisely adapted to actual demand, providing greater energy efficiency and significant savings — so even smaller upgrades can be worthwhile.
