Note
For the delivery of a liquid with density that
differs from water and/or kinematic viscosity,
the delivery output is reduced.
– Domestic hot water:
Permissible water hardness: max. 35°fH (20 °dH)
(water temperature below 65°C)
max. 25 °fH (14°dH)
(water temperature below 85°C)
To counter the risk of lime deposits, for domestic
hot water systems we recommend:
Hardness level max. 25°fH (14 °dH)
Medium temperature <65°C
Warning
The pump may not be used to deliver
combustible media such as diesel and fuel.
Warning
The pump may not be used to deliver
aggressive liquids such as acids or seawater.
