Predictive Maintenance Pumps Submersible Pumps There are dozens of different types of pumps and a seemingly endless list of applications but industrial accelerometers can often help the maintenance professional diagnose sometimes tricky issues with pump operation Using vibration monitoring in your predictive maintenance program can help identify pump problems such as cavitation recirculation and resonance A good rule of thumb is to select an accelerometer that has a linear high frequency response capability to three times the pump s vane pass frequency vane pass frequency of vanes x RPM Most general purpose accelerometers will have more than adequate high frequency response and thus the next key is selecting a transducer that will survive the application For this purpose IMI has a wide range of submersible accelerometers as well as sensors and cabling that will survive in corrosive environments Output Flange Input Flange Motor Suggested Sensor Placement 10 visit us online at www imi sensors com 1 716 684 0003
