API 610 clearances
(OP)
I have a 3600 rpm, double suction, pump with impeller wear rings that are approximately 7.375" diameter. Can anyone tell me what the proper clearance should be in this application? Fluid temp. is 250F.
Thank you.
Thank you.

You can go tighter with non-metallic (Vespel CR-6100 case rings for example) because the table only applies to metal on metal running clearances. That is where most of the improved efficiency claims come from for non-metallic rings.
