TEMPERATURE SENSOR (DRY RUNNING PROTECTION) - The dry running protection,
connectetd directly to the pump body by a sensor (1), stops the impeller
running when the internal temperature is higher than 50 °C, in order to avoid
burning or deformation. This protection is not suitable for the transfer of
liquids at a temperature higher than 45 °C.
ATTENTION! - The dry running protection device does not
interrupt
temperature is lower than 50 °C the pump automatically starts
working again.
