Magnochem-Bloc
The following limits must be observed:
▪ Maximum temperature: 300 °C
▪
Maximum pressure: 20 bar
DANGER
Excessive surface temperature
Explosion hazard!
Risk of burns!
▷ Observe the permissible temperature classes.
CAUTION
Lack of heating medium
Damage to the pump!
▷ Provide sufficient quantities of a suitable heating medium.
CAUTION
Time for warming up the pump too short
Damage to the pump!
▷
Check that the pump is sufficiently warmed up throughout.
CAUTION
Impermissibly high temperature of the heating medium
Fluid or heating medium could escape!
▷ Observe the application limits of the heating media.
6.1.5 Heating up the pump (set) and keeping it warm
CAUTION
Pump blockage
Damage to the pump!
▷ Prior to pump start-up, heat up the pump as described in the manual.
Observe the following when heating up the pump (set) and keeping it warm:
▪
Make sure that the temperature is increased continuously.
▪ 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.
Solidifying fluids Take the melting point of the fluid handled into account if the pump is used for
handling solidifying fluids.
Do not start up the pump set until the pump temperature is higher than the melting
point of the fluid handled.
