Pump bearing failure can be catastrophic and result in high cost repairs.  As the shaft moves it can damage impellers, wear rings, shafts and almost inevitably the mechanical seal.  Often it may be cheaper to purchase a new pump.  A bearing monitor can prevent this from happening by detecting the early stages of wear and warning of future failure.  The equipment below is simple to set up and use and provides permanent machine monitoring at a low cost. 

The IFM VKV021 compact vibration monitor is permanently mounted on the pump and constantly measures the rms vibration velocity.  When the adjustable limit value is exceeded the unit sets to alarm via a switching contact.  2 radial setting rings give easy set up of switch point and response delay.  4-20 mA signal provides input to controller.

The IFM efector octavis VB1001 is a compact vibration diagnostic unit which is easy to set up using PC software. 

The unit is sited in a radial direction to the axis of rotation, typically on the motor behind the terminal box or pump bearing housing, and is fixed with a screw mounting.

The detector continuously measures the vibration of 2 different bearings (VE001 monitors up to five bearings) and gives early warning and main alarm via the switching outputs.  Meanwhile the progressive wear is visible on the units integrated LED bar graph.
