Wilo-Extract FIRST - Intelligent Use of Rainwater

The Wilo-Extract FIRST is a multi-stage submersible pump designed for rainwater harvesting from cisterns or tanks in single-family homes and semi-detached houses. Thanks to its intelligent control, compact design and protective features, the pump enables reliable use of rainwater for domestic use - whether for supplying toilets, washing machines or watering the garden.

Benefits

• Easy installation thanks to integrated controller with automatic start-stop function
• Ready to connect - quick system start-up
• High operational reliability thanks to protection features, including dry-running detection
• Compact design for installation even with limited access to tanks
• Robust design with corrosion-resistant materials for long-lasting operation
• Flexible application - possible installation in wet mode or, in the SE version, also dry outdoors
