Pneumatic Design Series Vibrator

About Global’s Air Motor-Driven Vibrators

Our Pneumatic Design Series rotary industrial vibrators use an external air motor to drive the shaft mounted eccentric weights (the “unbalance”) to produce vibration. Because of their separate motor these vibrators can produce substantial force with moderate frequency. Air motor driven vibrators are larger and produce significantly more force than some of our other vibrator models. The largest Pneumatic Design Series Vibrator is capable of handling a load up to 268,700 pounds (121,880 kg) at 80 psi (5.5 bar). Use multiple vibrators on a single hopper based on the dimensions of the hopper and material weight. For more information please see:

Advantages of Air Motor Driven Rotary Vibrators

  • Rugged Construction - Ductile iron housings and lightweight hardened aluminum covers.
  • Vibrator Component Alignment - All manufactured equipment contain slight alignment variations due to manufacturing tolerances. Global’s Design Series vibrators have an unique drive coupling design, to compensate for typical alignment variations that exist when two shafts are connected (motor shaft and vibrator shaft). The coupling keeps the vibrational stress off the motor shaft seal. This prevents the motor from leaking because if the motor shaft is allowed to vibrate it would slowly destroy the seal making it ineffective. Some competitive vibrators use the conventional ‘shaft-in-a-shaft’ design; the drive motor shaft slips into the vibrator shaft. This design works only if both shafts remain in perfect alignment regardless of operating conditions. This arrangement often causes motor shaft flexing and fretting within the vibrator shaft, which leads to premature motor failure and a worn out vibrator shaft.
  • Drive Coupling Assembly - The drive coupling allows the motor shaft and vibrator shaft to operate as an "assembly", preventing fretting and stress from misalignment or expansion. Any misalignment or expansion wear takes place in the inexpensive and easily replaced coupling rather than in the motor or vibrator shaft. This superior design protects the motor shaft, vibrator shaft, bearings and seals from the vibration of the unbalanced weights. The result is better performance, no leaks, longer service, and reduced operating costs.
  • Bearings - All bearings are sealed to keep grease in and contaminants out. Our unique oil lubrication system in the D7 and CC7 models helps extend the life of the bearing. The coupling design isolates the unbalanced load from the motor, so the motor bearings see only a balanced load, extending bearing life. Grease lubrication is also available.
  • Air Motor Shaft Seal is isolated from the unbalanced load by the coupling design, extending the life of the seal and preventing air leaks.
  • High Efficiency, Durable, Bi-rotational Pneumatic Motor - Instantly reversible, can be stalled or overloaded without damage, self sealing vanes automatically adjust for their own wear ensuring constant output for thousands of hours.
  • Air Motor Repair Kits available to return motor to like-new condition.
  • Easy Repair and Maintenance - designed for easy change-out of bearings, motors, couplings, and other components to refurbish Design Series vibrators to like new condition. Bearings, o-rings, retaining rings, etc. are standard, commonly available parts.
  • High Amplitude, Moderate Frequency vibration.
  • Versatile - Easy to control force and frequency by adjusting air supply.
  • Available in Permanent Mount and Portable Clamp-on Mount. Clamp-on vibrators use square head set screws with concave cup points for positive self-locking and vibration resistance.
  • Produces Uniform, Directional Flow.
