What is a Pneumatic Piston Vibrator?

A pneumatic piston vibrator is a piece of equipment that is used to promote material flow by eliminating the formation of bridges and rat holes in storage containers such as bins, hoppers, bunkers, and silos. Air flowing through the alternating porting of the vibrator creates vibration. The size and porting of the vibrators can be changed to solve material flow problems in many different applications and industries including:

  • Food
  • Pharmaceutical
  • Chemical
  • Steel
  • Power
  • Mining and aggregate
  • Foundry

NAVCO Pneumatic Piston Vibrators are available in ten different sizes to handle a wide range of bulk material flow problems. Each size is offered in three distinct types of operation:

  • Impacting – Impacting units deliver a high-energy impulse with each stroke of the piston. The impacting model is the most effective of the three in eliminating difficult flow problems.
  • Silent – The silent units trap a cushion of air at the base of the piston, eliminating the impact. Although the silent models are quieter, a larger size is normally required.
  • Single Impact – Single impact models deliver a single high-energy impulse triggered by the output of a timer or other controlling device. Single impact units are particularly effective in applications where dry materials adhere to vessel walls.
