Varios PICO-STG
Glandless pump circulator
The most versatile replacement pump of all time.
- Universally deployable for heating, air conditioning, cooling, solar and geothermal energy applications
- Compact design as well as Wilo-Connector and Molex connection enable quick and easy installation
- Quick commissioning by means of 3-stage power adjustment for radiators, underfloor heating, alternatively with fixed speed
- With iPWM control for heating boilers and solar and geothermal energy applications
- Optional, custom adaptation by transferring the characteristic curve of the old pump using the Sync assistant
- Self-protection routines such as dry-running protection ensure operational reliability
- Easy maintenance and a high degree of operational reliability thanks to automatically and manually triggered reactivation or pump venting function
