HC HYDRAULIC ROTARY VIBRATOR
Hydraulic Motor-Driven Vibrators Vibtec’s Hydraulic Design Series rotary industrial vibrators use an external hydraulic motor to drive the shaft mount-
ed eccentric weights (the “unbalance”) to produce vibration. Because of their separate motor these vibrators can
produce substantial force with moderate frequency. Hydraulic motor driven vibrators are larger and produce signif-
icantly more force than some of our other vibrator models. The largest Hydraulic Design Series Vibrator is capable
of handling a load up to 355,000 pounds (161,000 kg) at a flow of 15.1 gpm (57 lpm). Use multiple vibrators on a sin-
gle hopper based on the dimensions of the hopper and material weight.
Advantages of Hydraulic Motor Driven Rotary Vibrators • Rugged Construction - Ductile iron housings and lightweight hardened aluminium covers.
• Vibrator Component Alignment - All manufactured equipment contain slight alignment variations due to
manufacturing tolerances. Vibtec’s Design Series vibrators have an unique drive coupling design, to compen-
sate 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 be-
cause if the motor shaft is allowed to vibrate it would slowly destroy the seal making it ineffective. Some com-
petitive 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 prema-
ture 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 un-
balanced 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 lubrica-
tion is also available.
• Hydraulic Motor Shaft Seal is isolated from the unbalanced load by the unique coupling design, extending
the life of the seal and preventing hydraulic leaks.
• High Efficiency - Durable, Bi-rotational Hydraulic Motor.
• Hydraulic 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 flow of the hydraulic oil.
• 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.
