4 Intended use
The high-efficiency circulators in the Wilo-Varios PICO-
STG series are exclusively designed for circulating fluids
in hot-water heating systems and similar systems with
constantly changing volume flows and/or in the primary
circuits of solar and geothermal systems.
Permitted fluids:
• Heating water according to VDI 2035
(CH: SWKI BT 102-01).
• Water-glycol mixtures* with a maximum of 50 % glycol.
* Glycol has a higher viscosity than water. If admixtures
of glycol are used, the pumping data of the pump must
be corrected to match the mixing ratio.
Intended use includes observing these instructions and
the specifications and markings on the pump.
NOTICE
Only introduce ready-to-use mixtures to the
system. The pump must not be used to mix fluid
in the system.
