Series DP - Rotary Pneumatic Vibrator

Portable design, adjustable vibration profiles, and force outputs ranging up to 6,500 lbs. provide wide-ranging options for offloading bulk materials in your operation, quickly and easily.

Four unit sizes provide diverse performance characteristics to handle a wide range of materials that can cause flow or sticking problems in covered or uncovered hopper railcars.
  • Use higher frequency models with moderate amplitude to loosen dry fine materials and avoid bridging, arching, or rat holing that can be experienced when materials have settled and compacted in transit.
  • Adjust the frequency output of any model to loosen hygroscopic materials that are more likely to stick together until the hopper starts to empty, then throttle back to save energy as the flow progresses.
  • Create high-amplitude motion to separate and energize large angular particles, ores, or aggregates with rough or angular surfaces that tend to wedge together in tapered chutes.
Whether you offload the same materials day after day, or need to adjust to multiple materials in one location, Deca DR Rotary Pneumatic Vibrators can handle just about any bulk materials:
  • Fine powders, chemicals, or cement
  • Plastic feed stocks in powdered, particle, or pellet form
  • Organic, hygroscopic materials such as wood chips or grains
  • Granular products such as sand or fertilizers,
  • Smooth gravel or angular crushed rock
VERSATILE PERFORMANCE ACROSS A RANGE OF UNITS
  • All DR Rotary Pneumatic Vibrators offer adjustable outputs - air pressure regulation and/or adjustable eccentric weights - providing flexibility to tailor vibrator performance to a wider range of materials.
  • Sealed pneumatic design performs equally well in extreme heat and cold, and stands up to the harshest, dirtiest, sloppiest work environments without worry about electrical hazards in wash-down applications.
  • Heavy-duty construction provides long life with the convenience of low maintenance for only periodic vane or bearing replacement.
  • Output frequency ranges run up to 15,000 rpm, depending on vibrator model and size.
  • Output forces up to 6,500 lbs. are capable of loosening and moving materials in the tapered portion of a railcar hopper.
  • Vibrator unit weights start as low as 17 lbs. for easier positioning and mounting in the field.
  • Versatile mounting styles offer convenience for frequent attachment and detachment on railcars as well as other bulk materials storage enclosures.
  • The ability to fine tune one unit to accommodate multiple bulk material properties provides more value from a single railcar vibrator model.
FLEXIBLE POWER ADJUSTMENT
Tailoring the right railcar vibrator to your application means being able to provide the right vibration profile for every type of material you need to offload - from fine powders, to hygroscopic materials, to coarse aggregates.

Deca DPC Series Rotary Pneumatic Vibrators offer several ways to adjust vibration patterns to match your material handling requirements.
  • AIR PRESSURE REGULATED models deliver frequencies up to 15,000 rpm and force output up to 6.500 lbs. at moderate amplitude. The ability to regulate speed and force output by reducing pneumatic drive pressure provides flexibility to tailor vibrator performance to a wider range of materials.
  • ECCENTRIC WEIGHT ADJUSTMENT on the DPC-35-3500 model can be combined with air pressure regulation available on every DPC model to vary both frequency and amplitude. High-amplitude output is ideal for the largest particles and most stubborn bulk materials.
CONVENIENT MOUNTING OPTIONS
In order to get railcars in and out of your offloading zone quickly and efficiently, consider the advantages of these proven railcar vibrator mounting options.
  • WEDGE MOUNT BASES make it easy to slip your railcar vibrator into the wedge-mount bracket built into most bulk material hopper railcars. Simply wedge it in, attach your air hose, and start a smooth and steady flow of offloaded materials.
  • CRADLE MOUNTING STYLES provide an easy way to adapt railcar vibrators to other bulk material handling uses. Once the railcars are emptied, you are able to remove the vibrator unit from the wedge-mount base and install it on a compatible cradle mount attached to any bulk material storage vessel in your facility.
RELIEVE THE PRESSURE OF MAKING THE RIGHT CHOICE
Choosing the right pneumatic vibrator is easier when you share your internal railcar offloading experiences with Deca representatives who have the benefit of 35 years of expertise matching vibrator performance across the full gamut of bulk materials.

Whether you are replacing an existing railcar vibrator or looking for a solution to new offloading problems, gain a greater perspective on your options. Call toll free, 866.384.3788, or write to Sales@Decavibrator.com.
