Wilo-Varios PICO-STG
The most versatile replacement pump of all time.
Wilo-Varios PICO-STG is the universal replacement solution for heating, air conditioning and cooling applications in detached and semi-detached houses. It can be used in pipe groups and heating boilers as well as for solar and geothermal energy applications. It can be put into operation very quickly and its output can be adjusted in three stages. The characteristic curves of the old pump can also be adopted via the Sync assistant.
