NAVCO Pneumatic Piston Vibrator

NAVCO Pneumatic Piston Vibrator

NAVCO is a manufacturer of Pneumatic Piston Vibrator, vibratory flow aid systems and equipment designed to assist in the handling, processing and packaging of bulk material. The NAVCO engineering team can develop customized solutions for specific applications including problem analysis, solution integration, and installation recommendations.

“NAVCO use applied vibration technology as a means to improve customers’ bulk material handling processes. NAVCO have been solving difficult flow problems for satisfied customers since 1955.”

Bin Hopper Vibrators (BH) Pneumatic Piston Vibrators

NNAVCO Bin Hopper Vibrators (BH) are available in 10 sizes to operate effectively in applications ranging from light to heavy duty. Available options include:

  • Tapped exhaust ports for routing exhaust air
  • Internal spring for horizontal mounting
  • Specialty coatings for extended life in harsh environments.

The large BH units are ideal for facilitating flow of coal, ore, steel and other bulk materials commonly stored in very large bunkers. The smaller BH units are the optimal flow aid for bulk materials in a large variety of industries, including chemical, food, grain, and pharmaceutical.

NAVCO manufactures over 70 different sizes and models of pneumatic piston vibrators for use in a wide range of bulk material handling and processing applications. NAVCO Pneumatic Piston Vibrator configurations are described below. .

  • The Impacting model (IGO)

    • develops a high amplitude repetitive impulse when the piston strikes the base of the bore sharply on each cycle. The piston is air cushioned at the head plate on the upward stroke. Energy is transmitted through the bin wall and into the material with each impact. Repetitive impacts allow the vibrator to overcome bulk material strength, affect a large area of influence, and reduce the wall friction. Impacting vibrators are ideal for bulk material that is cohesive or has poor flow characteristics. They are also effective for cleaning out adhering material from empty bins and process vessels.

  • The Silent model (SGO)

    • generates a sinusoidal output by creating an air cushion at each end of the piston stroke. NAVCO Silent Pneumatic Piston Vibrators are effective where non cohesive or free flowing material requires only a small amount of energy to produce flow or linear motion is needed.

  • The Timed Impact model (IGT)

    • delivers a single, high amplitude impulse each time it is energized. They are operated by a control device that sends intermittent signals to the unit. The impulse of this unit is ideal for evacuating hoppers and process vessels. Specific advantages of the timed impact unit are low noise level, controlled impact, and low air consumption.

  • Interior Specialty Coating for less wear and longer life
  • Single Tapped Exhaust
  • Dual Tapped Exhaust
  • Start Spring for horizontal Mounting/li>
  • Controls and Timers

    • Control systems reduce utility consumption and increase system life. A successful vibrator system installation requires a full understanding of the affected process. Integration of the vibrator system into the process can be accomplished via process feedback signals, simple timers, PLC or a combination. NAVCO offers simple to sophisticated control systems depending on the application.
