The rod displacement design eliminates metal to metal contact and does not contain wearable dynamic seals.
Closed loop servo drives enable the operator to program the mix ratio, shot size, flow rate, pressure control, vacuum degas, recirculation, and auto purge functions via a menu-driven HMI.
PVA’s rod displacement metering systems have many additional integrated features including:
- Carbide rod for long life
- Rugged steel frame eliminates tie rod design for easy set up and maintenance
- Four carbide rod sizes available for superior resolution
PVA manufactures single and plural component metering systems customized to each specific requirement. Standalone metering systems not integrated onto a PVA robotic platform come with a standalone controller allowing multiple dispensing profiles to be stored. Within each profile, automatic purge modes and variable flow rates are available. PVA metering systems feature closed-loop servo drives for added repeatability and dispense volume accuracy. All standalone meter-mix systems include an enclosure and are mounted in a frame or custom cart with casters.
