For more detailed, product-specific information such as power consumption, dimen-
sions and weights, refer to the technical documentation in the catalogue or Wilo-Select
online.

Fluids
Water-glycol mixtures or fluids with a different viscosity than pure water increase the
power consumption of the pump. Only use mixtures with corrosion protection. Observe
the relevant manufacturer's specifications!
ƒ
The fluid must be sediment-free.
ƒ
Wilo's approval must be obtained for the use of other fluids.
ƒ
Mixtures with a proportion of glycol of > 10 % influence the Δp-v characteristic
curve and the flow calculation.
ƒ
The compatibility of the standard seal/standard mechanical seal with the fluid is
generally given under normal system conditions.
Special circumstances may require special seals, for example:
–
solids, oils or EPDM-attacking substances in the fluid,
–
air content in the system, etc.
Observe the safety data sheet for the fluid to be pumped!
NOTICE
When using water-glycol mixtures, the use of an S1 variant with a corresponding
mechanical seal is generally recommended.
