Possibilities for energy saving result from measures to reduce the energy demand and energy loss as well as to recover energy. Specifically these are the following measures (Table E 2):
- Design improvements on pumps and valves by the manufacturer,
- Selection of designs with better efficiency by the user,
- Reduction of the power losses by means of corresponding dimensioning,
- Circuit-related measures such as the reduction of the throttling losses by means of the usage of multiple pumps or variable pumps,
- Energy-saving circuits (load sensing, closed circuit, motors with secondary regulation),
- Measures for energy recovery.
