The circulation pumps in the Wilo-Stratos ECO / BMS series
are designed for warm water heating systems and similar
systems with constantly changing flow volumes. An infinite
adjustment of the pump output to the actual heat demand of
the system is achieved with the electronic differential pres-
sure control of this pump.
The circulation pumps in the Wilo-Stratos ECO-Z / BMS series
are also suitable for pumping liquids in the drinking water/
process water sector and also the food sector.
The circulation pumps in the Stratos ECO-ST series are
suitable for use in thermal solar installations because of the
special coating of the pump housing (cataphoretic coating).
