6.3 Pumped liquids
In heating systems, the water must meet the requirements of
accepted standards on water quality in heating systems, for
example the German standard VDI 2035.
The pump is suitable for clean, thin, non-aggressive and
non-explosive liquids, not containing solid particles, fibres or
mineral oil. The pump must not be used for the transfer of
flammable liquids, such as diesel oil, petrol and similar liquids.
•
Maximum water/propylene glycol mixture is 50 %

•
Maximum 10 mm
/s viscosity
Note: The water/propylene glycol mixture reduces the
performance due to higher viscosity.
See section
10. Technical data
CAUTION
Flammable material
Minor or moderate personal injury
- Do not use the pump for flammable liquids, such
as diesel oil and petrol.
WARNING
Biological hazard
Death or serious personal injury
- In domestic hot-water systems, the temperature of
the pumped liquid must always be above 50 °C
due to the risk of legionella.
WARNING
Biological hazard
Death or serious personal injury
- In domestic hot-water systems, the pump is
permanently connected to the mains water.
Therefore, do not connect the pump by a hose.
CAUTION
Corrosive substance
Minor or moderate personal injury
- Do not use the pump for aggressive liquids, such
as acids and seawater.
