5.2 Technical data
Please state all the information on the pump name plate when order-
ing spare parts.
Fluids If water/glycol mixtures are used (or fluids with a viscosity other than
that of pure water), an increase in power consumption of the pump is
to be taken into account. Only use mixtures with corrosion inhibitors.
The respective manufacturer's instructions are to be observed.
• The fluid must be free of sediments.
• Wilo's approval must be obtained for use of other media.
• Mixtures with a proportion of glycol of > 10% influence the Δp-v
pump curve and the flow calculation.
