1) The minimum permissible speed is relevant for the oil lubrication of bearings and gears. Running the pump at less than the minimum speed for more than 1 hour can cause damage to the pump due to a lack of lubrication.
* at temperatures below freezing point, an appropriate mixing ratio with glycol must be observed.
** bar(g): bar(gauge) is the overpressure, for example, atmospheric pressure= 0 bar(g)
