Footplate Mount Piston Vibrators
P-Series Footplate Mount Vibrators

Piston vibrators use the impact action produced by the oscillating piston to flex the bin wall. This flexing action loosens material stuck to the wall, thus restoring material flow. In general, there are two styles of pneumatic piston vibrators: Impacting and Air-Cushioned (or non-impacting).

Impacting models allow the internal piston to strike the base of the vibrator, producing the greatest amount of force and frequency. Air-Cushioned models use a cushion of air to dampen the piston movement, so the piston reverses direction before impacting the vibrator base. Therefore, Air-Cushioned models are more quiet but also produce less force and frequency than the Impacting models.

Applications:

  • Used on bins, hoppers, railcars, foundry match plates, feeders, and concrete screeds.
  • Pneumatic piston vibrators are used for material handling problems that do not respond well to high-frequency rotary vibration. They can be effective where other devices fail, freeing materials that tend to cling, clump, or stick, such as damp or oily solids.
  • Piston vibrators are also used where the air supply is limited, because they consume much less air than most pneumatic rotary vibrators.
  • The linear force of a piston vibrator can produce the back-and-forth motion needed for feeders and shaker screens.

Features:

  • Maximum Force - Impact (IM) model produces maximum force & frequency for size of vibrator.
  • Quiet Model Available - Air-Cushioned (AC) model produces less noise than Impact models.
  • Energy Efficient - Low air consumption.
  • Durable - Iron uni-body construction with chrome plated piston.
  • Versatile - Easy to control force and frequency by adjusting air supply.
  • Long Life Railcar Models - Teflon® coating on piston and bore give extended life.
  • One Year Warranty

Options:

  • Available in either Impact (IM) type or Air-Cushioned (AC) type.
  • Railcar Models (PRR) - Come standard with wedge mount to fit railcar pockets and Teflon® coated piston and bore.
  • Matchplate Models (MP) - Impact type with universal base mount used on foundry matchplates. Internal spring allows any mount orientation.
  • Timed Impact Models (TMD) - For use with electric or pneumatic timers.

Operating Requirements:

  • Filtered, lubricated air.
  • 20-60 PSI depending on model. 1.5-30 CFM.
  • Maximum Ambient Temperature = 250F (120C).

Vibrator Selection:

  • Since piston vibrators create material flow by flexing the bin wall, selection of the proper vibrator is based on the bin wall thickness. The thicker the wall the bigger the vibrator needed.
  • If selecting a more quiet Air-Cushioned model you generally use one size larger than an Impacting model sized for the same application. Refer to the chart below.

Accessories:

  • Manual Valves - 2-way manual ball valve used to turn the vibrator on and off for normal operation. 3-way manual ball valve used to turn the vibrator on and off when rapid on/off/on operation is required.
  • Solenoids - For remote or automated control, use 2-way normally closed solenoid valve to turn the vibrator on and off for normal operation or 3-way normally closed solenoid valve when rapid on/off/on operation is required.
  • Airline Kits - Required for trouble-free operation and long life of piston vibrators. Includes airline filter, lubricator, and pressure regulator with gauge.
  • Internal Spring - Can be added for operating piston in horizontal plane.
  • GBF Bracket - Female pocket bracket that accepts universal wedge-shaped male bracket found on portable vibrators such as P-Series Railcar Piston Vibrators.
  • Sirometer - Convenient, compact RPM Meter for measuring vibrator speed.
