6.2.1 Glycol
You can use the pump for pumping water-ethylene-glycol
mixtures up to 50 %.
Example of a water-ethylene-glycol mixture:
Maximum viscosity: 50 cSt ~ 50 % water / 50 % ethylene-glycol
mixture at -10 °C.
The pump has a power-limiting function that protects it against
overload.
The pumping of water-ethylene-glycol mixtures affects the
maximum curve and reduces the performance, depending on the
water-ethylene-glycol mixture and the liquid temperature.
To prevent the ethylene-glycol mixture from degrading, avoid
temperatures exceeding the rated liquid temperature and
minimise the operating time at high temperatures.
Clean and flush the system before you add the ethylene-glycol
mixture.
To prevent corrosion or lime precipitation, check and maintain the
ethylene-glycol mixture regularly. If further dilution of the supplied
ethylene-glycol is required, follow the glycol supplier's
instructions.
