Model Types (model descriptions apply to all NAVCO vibrators)

Impacting

IGO (Impacting) The IGO model 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. Momentum and energy are transmitted efficiently through the bin wall and into the material by each elastic collision between the piston and the vibrator base. The repetitive impacts enable the vibrator to affect material over a large "area of influence" overcoming the bulk material strength and reducing the wall friction angle.

Silent

SGO (Silent) The SGO model generates a sinusoidal output by creating an air cushion at each end of the piston stroke. NAVCO^® Silent Pneumatic Piston Vibrators are ideal when noise levels are a concern and are effective in applications involving non-cohesive free flowing materials where a slight increase in energy is required to initiate or maintain flow. The silent units are also ideal as drives for vibratory tables and feeders.

Timed Impact

IGT* (Timed Impacting) Timed impact models deliver a single high amplitude impulse each time it is energized. NAVCO^® Timed Impact units may be operated using a pneumatic or electronic timer, programmable controller, or any other device that can deliver an intermittent control signal to the unit. The impulse of a timed impact unit is very effective in evacuating hoppers and process vessels.Specific advantages of NAVCO^® Timed Impact units are low noise levels and very low air consumption.

*The BH 1" and HCP are not available in IGT (Timed Impacting)
