Protection class I I
Max. system pressure 10 bar 10 bar
Permitted temperature
range of pumped fluid** -10 °C to +110 °C -10 °C to +110 °C
Permitted pumping
media*** Heating water according to VDI 2035,
water/glycol mixtures
* The benchmark for the most efficient circulators is
EEI ≤ 0.20
** Must not freeze. To avoid condensation the fluid temperature must always
be higher than the ambient temperature. For Domestic Hot Water
applications the max fluid temperature is 85°C
*** Performance of the pump will noticeably change when pumping
water/glycol mixtures with concentrations higher than 20%.

6. Installation Advice
The installation of a stop valve upstream and downstream of the pump
is recommended so the pump can be replaced at a later time without
the need to completely drain the system.
7.
Installation
The unit must not be installed in areas where there is a
danger of explosion and must not be used to pump
flammable liquids.
