Grundfos Pump UPS 32-120

Ensure the system is turned off

Verify that the pump is suitable for water-glycol mixtures up to 50%

Measure the viscosity of the glycol mixture

Is the viscosity within the acceptable range (approx. 32 cSt at -10 °C)?

Clean the pump and surrounding area

Was the pump performance checked after cleaning?

Verify the following conditions

Is the glycol mixture concentration within the acceptable range (up to 50%)?

Is the viscosity of the glycol mixture at -10°C approximately 32 cSt?

Describe any observed reduction in pump performance when using glycol mixtures

Corrosion and Precipitation Prevention

Check the glycol mixture for signs of corrosion or precipitation
