Please state all the information on the pump name plate when order-
ing spare parts.
If water/glycol mixtures with up to 40% glycol (or fluids with viscosi-
ties different from pure water) are used, the pump data must be cor-
rected accordingly (depending on the percentage mixture ratio and
fluid temperature). The motor power must also be adjusted if neces-
sary.
• Only use mixtures with corrosion inhibitors. The respective manufac-
turer'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.
NOTE:
The safety data sheet of the pumped fluid must always be observed!
