▪ Max. heating speed: 10 °C/min (10 K/min)
Fluid temperatures above
150°C
When the pump is used for handling fluids at temperatures above 150°C make sure
that the pump has been heated throughout before starting it up.
Temperature difference The temperature difference between the pump's surface and the fluid handled must
not exceed 100 °C (100 K) when the pump is started up.
