  • Resonant Frequency and Critical Speed Pumps Systems

     · For the first critical speed to become a concern at four pole speed shaft deflection would have to be greater than 0.010-in. A pump with a shaft deflection of 0.006-in but driven by a two pole motor (3 600-rpm) will operate well above its first critical speed. As I mentioned earlier this is not a concern in constant speed applications because
