Not much can go wrong w/ centrifugals, as long as the motor itself is not

Mebbe amprobe the motor.
But, if the impeller itself is gunked up, then that would f'sure reduce your
pressure--basically just a wheel, then, spinning in coolant!
If back-blowing the line don't help, start sleuthing: disconnect hoses,
perhaps right at the pump outlet, see what happens w/ the flow.
I got nice pumps (for Hurcos) at Traverse Tool for $180. Similar to what's
on my fadal.

I just put a pump on a mazak. Stole it off an old okuma LC 10 that I
scrapped a while ago. They run all nine wires back into the control
cabinet and do the 240/ 480 switching in the cabinet.
