Piston Fillers
PF Series Liquid Depositor
The PF Series Liquid Depositor is a precision-engineered piston filling machine built to deliver accurate, gentle product dispensing across a broad spectrum of applications. Designed specifically for demanding food packaging environments, it handles everything from thin, free-flowing liquids (such as water or sauces) to highly viscous products (like mashed potatoes, puddings, dips, or salsas) while meeting strict sanitary and regulatory standards.
In a typical production line, containers are denested and conveyed into position. The PF Series then performs the critical filling step—depositing the exact volume of product into each container before it moves on to sealing. Its reliable piston technology ensures consistent fill weights, minimal product waste, and preserved product quality, even at higher speeds.
Key Features & Benefits
- Wide viscosity range — Effortlessly manages products from water-thin to thick, chunky, or semi-solid formulations.
- Ultra-fast sanitation — Fully disassembles in less than 60 seconds with no tools required, minimizing downtime and supporting rigorous cleaning protocols.
- Robust, hygienic construction — 100% stainless steel frame with FDA-approved plastic contact parts for durability, corrosion resistance, and compliance in food-grade environments.
- Seamless integration — PLC controls simplify communication with upstream denesters, conveyors, and downstream sealers, allowing easy retrofit into existing lines.
- Flexible hopper options — Multiple hopper sizes available to match your batch or continuous-run requirements.
Available Options for Customization
- Agitated hoppers for products that tend to separate
- Multi-head configurations for higher throughput
- Diving nozzles to reduce splashing and foaming
- Spreader valves for even distribution in wider containers
- Level controls and checkweigher feedback for closed-loop accuracy
- Servo-driven operation for enhanced precision and speed
Whether you run high-volume retail packaging or specialized food-service lines, the PF Series Liquid Depositor combines rugged reliability with the flexibility to grow with your operation. Its sanitary design and precise performance help you maintain product integrity, reduce waste, and meet the highest industry standards—all while keeping changeovers fast and labor efficient.
