VS Series High-Volume Screw Pump Dispenser
For high-throughput automated dispensing and thermal encapsulation production lines, our VS Series Large-Capacity Volumetric Screw Metering Valve serves as a robust core dispensing unit, specially engineered for accurate volumetric dosing of structural sealants, gap fillers and high-filler thermal conductive adhesives.
This auger metering dispensing head is purpose-built for continuous uniform coating of pasty adhesives, formed-in-place sealants and potting compounds. Leveraging its low-shear screw conveying principle, the valve delivers ultra-gentle, low-pulsation material feeding, fully compatible with shear-sensitive formulations and heavy high-viscosity media without material degradation or bubble generation.
It demonstrates outstanding performance in high-filler thermal conductive adhesive conformal coating and thermal gap sealing workflows, widely adopted for new energy battery PACK, electric drive housing and power module thermal management processes. Designed for long-cycle mass manufacturing, the VS series screw valve features stable mechanical structure to shorten equipment downtime and slash routine maintenance expenditure, helping manufacturers significantly lower total production operating costs.
Fully compatible with self-leveling adhesive supply systems, vacuum pressure plate pump feeding stations and bubble-free feeding systems, it seamlessly pairs with dynamic mixing heads, two-component AB epoxy dispensing equipment and large-scale in-line vacuum potting machines. Matched with multi-layer curing ovens, it forms a complete automated dispensing production line for flat wire motor stator dripping coating, ECU & BMS potting, power semiconductor encapsulation, FIPG housing sealing and cylindrical cell gap potting scenarios.
