6.3.9 Heating up/keeping warm the pump (set)
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.
6.3.10 Final check
1.
Remove the coupling guard and its footboard, if any.
2.
Check the coupling alignment; re-align the coupling, if required.
(
ð
Section 5.6, Page 29)
3.
Check proper functioning of coupling/shaft.
Check that coupling/shaft can be easily rotated by hand.
4.
Fit the coupling guard and its footboard, if any.
5.
Check the distance between coupling and coupling guard.
The coupling guard must not touch the coupling.
6.3.11 Start-up
DANGER
Non-compliance with the permissible pressure and temperature limits if the pump
is operated with the suction and/or discharge line closed.
Explosion hazard!
Hot or toxic fluids escaping!
▷
Never operate the pump with the shut-off elements in the suction line and/or
discharge line closed.
▷
Only start up the pump set with the discharge-side shut-off element slightly or
fully open.
