5.2 Technical data
When ordering spare parts be sure to state all the information given
on the pump and motor type plates.
Fluids If water/glycol mixtures with up to 40% glycol (or fluids with a differ-
ent velocity to pure water) are used, the pump data must be corrected
to match the higher viscosity, regardless of the percentage mixture
relationship and the fluid temperature. The motor power must also be
adjusted if necessary.
• Only use mixtures with corrosion inhibitors. The respective manufac-
turer's instructions are to be observed.
• The fluid must be sediment-free.
• Wilo's approval must be obtained for use of other media.
NOTE
Always read and follow the material safety data sheet for the fluid
being pumped!
