3 Description and function
3.1 Intended use
The circulation pumps in this series are designed for warm
water heating systems and similar systems with constantly
changing flow volumes. Approved fluids are heating water
in accordance with VDI 2035, water/glycol mixture at a mix-
ing ratio of 1:1. If glycol is added, the delivery data of the
pump must be corrected according to the higher viscosity,
depending on the mixing ratio percentage.
