GFP / GZZ Series Gravity Filling Machine
Engineered for Water & Low-Viscosity Liquids. Stable Filling, Cleaner Bottle Presentation, Flexible Production.
Equal Liquid Level Filling: Negative-pressure low-vacuum filling helps reduce foaming and keeps the liquid level more consistent in every bottle.
Linear Gravity Flexibility: Wide filling range, compact structure, and digital adjustment make the GZZ series suitable for flexible production needs.
Bottle Protection: Elastic bottle support and bottle-mouth positioning help reduce bottle damage and keep filling heads aligned.
Easy Maintenance: Simple structure, convenient cleaning, and low maintenance cost help reduce downtime in daily production.
High-Performance Gravity Filling Technology
The GFP / GZZ Series Gravity Filling Machine is designed for water and other low-viscosity liquids that require stable operation, clean bottle presentation, and efficient daily production. This product family includes two practical filling solutions: the GFP Automatic Equal Liquid Level Filling Machine and the GZZ Linear Gravity Filling Machine. The GFP series adopts negative-pressure low-vacuum filling to reduce foaming during the filling process, while the GZZ series offers a large filling range, compact structure, and convenient digital control for flexible line applications.
It can be used as a standalone filling machine or integrated into a complete liquid packaging line. Qingzhou Tongda Packaging Machinery has more than 20 years of manufacturing experience and supplies complete line equipment covering rinsing, filling, capping, drying, labeling, carton packing, and water treatment systems. The company operates under a strict quality management system and its products have passed ISO 9001 and CE certification.
Automatic Equal Liquid Level Filling
The GFP series is built for manufacturers who care about bottle appearance, controlled foaming, and stable equal-level filling performance.
Negative-pressure low-vacuum filling is adopted to effectively reduce foaming during the filling process. At the same time, liquid flows down along the inner wall of the container, which helps suppress foam caused by liquid impact at the bottle bottom.
The Solution: Helps solve common filling problems in water-like liquids, such as unstable bottle presentation, excessive foam, and inconsistent visual liquid level.
Linear Gravity Filling for Flexible Production
The GZZ series is a linear gravity filling solution designed for customers who need wider filling volume coverage and convenient production adjustment.
Its main features include a large filling range, high precision, compact machine body, and digital display control based on actual measurement correction. It is easy to operate, easy to clean, and convenient to maintain, while the maintenance cost remains low.
The Solution:Provides a practical filling platform for factories that need to handle different bottle sizes or filling volumes without moving to a more complex filling architecture.
Stable Filling Valve Structure
The GFP series uses a precise filling valve structure with fewer seals, delivering reliable and durable performance over long-term operation. Its valve structure is also simple, making disassembly and cleaning more convenient for daily maintenance.
The Solution:Reduces maintenance complexity while helping factories maintain stable production and product consistency.
Bottle Protection & Filling Accuracy
The GFP series uses a special elastic bottle support structure, allowing the bottle to be lifted more gently during filling and effectively reducing bottle damage. The GZZ series uses a bottle-mouth positioning device to keep the filling head aligned, while its ball screw diving and lifting mechanism ensures stable up-and-down movement.
The Solution: Improves line stability, lowers bottle loss, and helps maintain accurate filling position even in continuous production.
Foolproof Operation & Automation
Meticulously designed with advanced sensing and logic control systems, it ensures zero-fault operation and maximizes production efficiency.
