In a way, I'm with DERG on this. Time to call in ye old pump engineer. Tell to bring his cavitation check list. Go down it item by item. One of them hasn't been looked at hard.

Slush - NOT

Fuel /ice slush? Think about this. At the point where the pump goes into cavitation, the fuel pressure at the pump inlet falls to near zero. And the near zero pressure will extend back through the...

Resonance ...not

If the oil heat exchanger is located in the pipe network of only one side, then the separate systems are not mirror images of each other. Similar resonance to dis-similar systems at about the same...

I'm already on record for a theory. I'll go a bit more.

The permanent fix is to change the gear ratio for a reduction in pump speed and an increase in pump size to maintain the flow capacity.

pump cavitation

Pump output can be greatly diminished by cavitation and would give the results seen in this case.

The HP gear pumps show evidence of cavitation. Two of the principle determinants for the point at...
