What causes the mother liquor circulation pump not to draw in liquid? Our factory replaced the saturator today. But the mother liquor circulation pump isn’t pumping liquid – what could be the reason? This post was last edited by yfq4308 on 2009-2-27 17:58.]
Look at the inlet and outlet pressures of the pump. There must be no vacuum in the container connected to the inlet, and no pressure higher than the head pressure in the container connected to the outlet. If everything is fine, check for any blockages in the pipelines; the mother liquor tends to crystallize easily.
There is a high possibility of crystallization blocking at the pump inlet. Pump impeller ； Key nitro removal ； The locking nut is too loose, etc. Check for things like motor reversal, etc.
You can check whether there is any air left in the pump chamber of your circulation pump, as this could cause dry pumping; add liquid to it
The problem is solved, thank you all!
