Gear pump designs feature continuous material flow with no recharging necessary. PVA pumps are designed specifically for processing a wide range of adhesives and sealants.
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 gear pump metering systems have many additional integrated features including:
Continuous pulse-free flow
High pressure capability up to 4000 psi
Wide viscosity range to 3 million cps
Superior resolution as pumps are sized to each application
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.
