Note that water-glycol mixtures or fluids with a viscosity that is different to that of pure
water increase the power consumption of the pump.
The pumping data must be adjusted according to the higher viscosity of the fluid, regard-
less of the proportion of viscous substances.
Only use brand products with anti-corrosion inhibitors. Strictly follow the manufacturer's
instructions and safety data sheets!
When ordering spare parts, specify all data on the pump/motor rating plate.
