Wilo-Varios PICO-STG – The most versatile replacement pump ever

The Wilo-Varios PICO-STG is the universal replacement solution for heating, air conditioning, and cooling applications in single and two-family homes. Thanks to its flexible application possibilities, it is also ideal for solar and geothermal systems. With its compact design, the Wilo-Connector, and the Molex connection, installation is quick and uncomplicated.

The pump can be optimally adapted to the respective application via three power levels – alternatively, it automatically adopts the characteristic curves of the old pump with the Sync Assistant. Intelligent protection functions such as dry-running protection and an automatic deaeration and restart function ensure continuously safe and low-maintenance operation.
