Watch: Our MSV Pellet Feeder in action.
Thayer Scale’s Model MSV Pellet Feeder is compact, easy-to-clean and economical.
Precise rate control for free-flowing pellets and granules.
The Thayer Scale MSV Pellet Feeder offers precise feed-rate control for free-flowing pellets and granules. Featuring a new mass-counterbalanced low-profile cable scale with a robust, highly stable micro-lever system that delivers higher accuracy, fast responsiveness, longer gravimetric cycles and higher turn-down. The MSV is designed in a small form-factor providing flexibility and efficient use of floor space.
The MSV Pellet feeder includes Thayer Scale’s low-profile cable scale utilizing a micro-lever system which counterbalances the tare weight, resulting in load-cell utilization significantly higher than other options. The higher load-cell utilization provides numerous benefits: higher accuracy, typically 0.25% of feed rate, fast responsiveness to changes in set point or material density fluctuations, resulting in higher quality ration material delivery and the elimination of “dead zones” common in gravimetric feeding applications.
Our MSV Pellet Feeder also has longer gravimetric cycles, requiring fewer refills and less time operating in volumetric or “settling” mode and significantly higher turn-down. The system is designed to operate with the Thayer Scale Differential Screw solution, enabling consistent, pulse-free delivery of materials across a wide operating range.
Industry Applications
Suitable for free-flowing pellets and granules.
- Plastics & Polymers: Polypropylene (PP) Pellets, LLDPE Pellets, Polyethylene Pellets, Nylon Pellets, Polyolefin (PP) Pellets, Pc Pellets, PVC Pellets
“The MSV Pellet Feeder is an ideal solution for free-flowing materials such as plastic pellets and granules. By pairing a high-resolution, mass-counterbalanced scale with a fast change-over, low-maintenance, industrial feeder, we believe the MSV will become the workhorse for our customers looking for an economical yet accurate feeding solution.”

Core Technologies
🎚️ Low-Profile Cable Scale & Micro-Lever System
Thayer Scale’s new low-profile cable scale uses a micro-lever mechanism to counterbalance tare weight, delivering much higher load-cell utilization than conventional designs. The result: greater accuracy (typically ±0.25% of feed rate), faster response to set-point changes or density shifts, more stable ratio control, and the elimination of dead zones common in gravimetric feeders.
🔩 Thayer Scale Differential Screw
The MSV Pellet Feeder utilizes Thayer Scale’s Differential Screw technology to deliver consistent, pulse-free material flow across a wide operating range.
⚖️ Fully Mass-Counterbalanced Cable Suspension Scale
Maximizes load cell utilization by measuring only the live load and isolating the material weight signal from vibration, shock, and external forces.
🧩 Strain Gauge Load Cell
Rugged and accurate, rated 25–500 lbs. with 300% overload protection.
📟 S52C Weigh Feeder Controller
When used in conjunction with the Thayer Scale S52C instrumentation, the MSV provides a powerful control solution for free-flowing materials like plastic pellets, granules, and additives.
Key Benefits
of Thayer Scale’s MSV Pellet Feeder
🎯 High Accuracy for Inventory Control & Documentation
Gravimetric system ensures precise feed rates, making the feeder ideal for inventory tracking, process validation, and regulatory compliance. Ideal for manufacturers needing to provide on-going process documentation or validation to consumers.
🧼 Easy To Clean & Maintain
Quick-release, tool-free changeover of screws and tubes. Rapid clean out of the V-through feed section and standard feeder guide-rail options available to provide easy access to downstream apparatus.
📐 Flexible Modular & Compact Design
Compact design provides flexibility and efficient use of floor space. Flexible modular design enables clustering of up to 6 feeders.
🧱 Built to Survive
Trusted for over 75 years. Unlike lightweight designs made for short-term convenience or scale sensitivity, our feeders are engineered for long-term durability, without compromising accuracy.
