Film Pro (FP32) Circulation Pump


Recommended Posts

Problem with film pro not coming up to temperature.  Heater element is hot.  From what I can see the circulation pump for the Fix 2 tank pumps fix solution through pipe through Fix 1 and Bleach tank, to warm them up.  The circulation pump (Iwaki Magnet Pump MD-10-NL02) seems hotter that the others.  I took it apart and can not see anything amiss, all looks clean, the impeller spins round no problem.  When I reconnected water flowed through the pump just from gravity.

So is there anything else to check before I look for a new pump?
