Holmatro‘s new ECO whisper mode reduces noise and fuel consumption by running on low-idle speeds. It is available on three pump models.
The ECO whisper mode works in combination with Core hoses up to a length of 50 feet. Once connected to a running pump, press the ECO button to activate and optimize the function.
These Holmatro Spider range pumps are equipped with the ECO whisper mode: SR 10 PC 1 E, SR 20 PC 2 E, SR 40 PC 2 E. Conversion sets to retrofit existing equivalent pumps with the ECO whisper mode is also available.
