For the delivery of a liquid with density that
Note
differs from water and/or kinematic viscosity,
the delivery output is reduced.
– Domestic hot water:
Permissible water hardness: max. 35 °fH (20 °dH)
To counter the risk of lime deposits, for domestic
hot water systems we recommend:
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.
