As usual, all guess work based on insufficient data, round and round tail chasing - let's get some real information and save everyone's time.

The application details and the current pump selections, including the performance curve would certainly help to clarify your concerns.

There is no need for a "giant dust thingy" do an internet search and you might be surprised what you turn up.
"small dust cyclone" might help.

Look at cyclone dust extracter.

Agree with 3DDave, probably more effective to seal the plaster models.

Good luck with that, but I would be surprised if that's the cause.

Always difficult to analyse installation problems from a distance, however the very basics should be checked initially before removing and dismantling pumps.
1, is rotationc correct
2.have gauges been checked
3. are all valves fully operational and open,
4. Double check everything, never assume...
Double check all instrumentation and readings before worrying about the pump.

Time to employ an experienced pump / system design designer, it's way beyond trying to use a free website for answers.
Give a bit more information and at least you might get a few ideas as how to best approach this application.

Just a little bit of additional info might assist, but please don't over do it and confuse everyone.

BrianPeterson: what, isn't your crystal ball functioning?

Pump duty power will increase by atleast 25%, therefore supply current will need to be considered as well.

is there any reason why the baseplate can't be removed and spacer pads welded onto the existing positions, redrilled and the whole baseplate machined?

Probably,
what happens when you fill container B
how do you return the piston to its original position
is it a continuous operation.

Your question has been answered, for a standard mass produced pump of this size, the efficiency quoted is in the right ball park.
For higher efficiencies you need to be looking at much larger well engineered pumps built to exacting standards, and yes you can get to 90% plus but certainly not at...
Under the motor, yes.

Depends on the baseplate / boltdown location - are the mounting pads machined and level etc, a poorly designed base might require some shim to ensure the pump case is not stressed or twisted.

Yes.

I think you could dismiss the suction pipe work as being the cause as there is certainly enough straight run of pipe after any bends etc leading to the pump inlets to ensure flow into the 3 units is ideal, the only other concern could be some form of pre-rotation - however this would be a long...
Heavyside1925:
Looks more like corrosion erosion than cavitation, to the point I would say it's not cavitation.
A few photos of the impeller would be of interest.
