This pneumatic servo dispensing system is a positive rod displacement metering system that combines the cost efficiency of a pneumatic drive motor with the controllingaccuracy or a servo drive motor. The PSD system uses a positive rod displacement metering principle for maximum dispensing precision and eliminates the need for a servo drive motor or manual flow meters in a dispensing system. The PSD integratesa pneumatic drive motor and servo package to provide precise metered volumes, accurate flow control and consistent bead profiles. The PSD's pneumatic cylinder and positive displacement meter are lightweight and assembled into a single compact metering module for floor, robot or pedestal mounting.
