A positive rod-displacement dispenser combines the cost efficiency of a pneumatic-drive motor with the controlling accuracy of a servo-drive motor. The Pneumatic Servo Dispensing (PSD) system uses a positive rod displacement metering principle for maximum dispensing precision and eliminates need for a servo-drive motor or material-flow meters in dispensing equipment.
The PSD works with a 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. A robot integrated PSD system provides precision dispensing of fluids with excellent response time for dispensing extruded beads.
The PSD is intended for long life and maximum uptime. Components are readily accessed and easy to maintain. Users operate the PSD by its own control panel or by automation integrated controls with dispensing software for a smaller footprint, lower system cost, and one-stop operator control of the entire robotic dispensing system. The unit is well suited for dispensing adhesives, filling, gasketing, molding, sealing, other operations.
