Bigger motor and pulley on Sanborn pump?
by Charles Durfey
I bought older a 5HP 60 GAL Sanborn--500B60V and want to know if I put a bigger electric motor, say 6 or 7HP, and put a larger diameter pulley on the motor if I would get more CFM. Would it hurt the pump? I would not increase the pressure shut off limit of 125lb.
What is the max. RPM of the pump?
