Any nozzle used with an eductor must be able to flow the rated gpm of the eductor.
If it is a 95gpm eductor, the nozzle must be capable of flowing 95gpm.
If the eductor is rated at 125gpm, the nozzle must be capable of flowing 125gpm.

Why?......Consider using a 95gpm nozzle with a 125gpm eductor. If the nozzle can only flow 95gpm, then only 95gpm is flowing through the eductor even when set at 200psi. This creates back pressure affecting foam pickup ability and changes the % of foam being applied. Lower % concentration may not effectively suppress/protect.
DO NOT USE A NOZZLE WITH LOWER GPM FLOW THAN THE EDUCTOR'S RATED GPM!
If any mismatch was to be made it would be better to have a higher gpm flowing nozzle than the eductor. Stream reach would be negatively affected but the finished foam product would most likely be OK but with an increased concentrate of foam solution. Higher percent concentration uses up foam supply faster without the need. Flowing more or less through the eductor has effects similar to what a mismatched nozzle can create and giving more psi to the eductor can actually decrease you foam percentage.

Example using a 6% eductor setting,

(we will not have to use 6% setting with our 3%-3% foam, table is just for demonstration of effect),

Having to match eductors & nozzles does not rule out more foam lines used off of one apparatus.
Two foam lines (or more) may be needed for a proper application rate.
The 2nd-in pumper may distribute their foam equipment to the 1st-in attack pumper. As long as both foam lines have matched equipment, 200psi at the eductor and appropriate line lengths the system will work. If the attack pumper is in proper position for the given incident, using one pumper will only require water supply operations to one pumper.
