Model V4™ Volumetric Powder Feeder
Volumetric powder feeder engineered for thermal spray processes such as HVOF, HVAF, Plasma, Cold Spray, Laser Cladding, and a wide range of other industrial applications. The V4 is a heavy-duty volumetric powder feeder featuring a patented powder-feeding mechanism that ensures consistent, pulseless delivery of thermal spray powders, while eliminating powder after-flow through the spray torch upon shutdown.
Key Features - V4 Powder Feeder
● Pulseless Powder Feeding
Delivers smooth, pulse-free powder flow for uniform coatings and reliable process control.
● No Wearing Seals
Designed without consumable seals, eliminating the need for frequent replacements or maintenance.
● Minimal Consumable Requirements
Requires virtually no consumables, minimizing maintenance and operating costs.
● Quick Start/Stop
Responds instantly to control commands with no powder afterflow, minimizing powder loss and ensuring clean operation.
● Feeds Poor Flowing Powders
Capable of handling even traditionally difficult-to-feed powders with stable, consistent performance.
● Backpressure Insensitive
Maintains stable powder flow regardless of downstream pressure variations.
● Precise Feed Rate Control
Closed-loop motor regulation maintains constant wheel speed under varying load conditions, providing precise and repeatable feed-rate control.
● Consistent Feed at Any Powder Level
Delivers uniform powder flow throughout the entire hopper capacity, maintaining stable performance even at very low powder levels.
● Local & Remote Control
Supports both standalone operation and seamless integration into automated control systems.
● Heavy-Duty Design
Built for long-term reliability and durability in demanding industrial environments.
● Quick Cleaning & Maintenance
Simplified design allows for fast cleaning and reduced downtime between jobs.
● ASME Code Compliance
Engineered in accordance with ASME pressure-vessel code specifications to ensure safety and regulatory compliance.
