GFP / GZZ Gravity Filling Machine
Built for Water & Low-Viscosity Liquids. Stable Filling, Clean 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.
Gravity Filling Machine Technology for Daily Production
The GFP / GZZ Series Gravity filling machine is built for water and other low-viscosity liquids that require stable filling, clean bottle presentation, and efficient daily output. It includes two practical solutions: GFP automatic equal-level filling and GZZ linear gravity filling. GFP uses negative-pressure low-vacuum filling to help reduce foam, while GZZ offers a wide filling range, compact structure, and convenient digital adjustment.
We build this series for standalone filling or full line integration. At MotivaPAC, we bring 20+ years of liquid packaging experience, 18,000 m² of factory space, 12,000 m² of standardized workshops, advanced CNC machining capability, and ISO 9001 plus CE-certified manufacturing to every project.
Linear Gravity Filling for Flexible Output
The GZZ series Gravity filling machine 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: Best for lines that handle multiple bottle sizes or frequent volume changes with straightforward operation.
Automatic Equal-Level Filling
The GFP series gravity filling machine 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: Best for water-like liquids where foam control and a cleaner visible fill level matter.
Bottle Protection & Filling Accuracy
The GFP series Gravity filling machine 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.
Stable Filling Valve Structure
The GFP filling valve uses a precise structure with fewer seals for reliable, durable performance. Its simple layout also makes disassembly and cleaning faster in daily production.
The Solution:Reduces maintenance complexity while helping factories maintain stable production and product consistency.
Practical Control & Automation
Integrated control logic helps keep filling stable, reduce manual correction, and support dependable daily operation.
“No Bottle, No Fill” Safeguard
The GFP series gravity filling machine skips missing bottles and bottles with defective mouths, helping protect finished product quality.
Digital Display Control
The GZZ series gravity filling machine adjusts filling time through actual measurement correction and digital display control, making daily operation more convenient.
Automatic Fluid Replenishment & Return
The GZZ series gravity filling machine supports automatic fluid replenishment and fluid return without manual intervention, helping simplify production management.
Unique Positioning Control System
The GZZ series gravity filling machine features a unique positioning control system that helps prevent photoelectric miscounting.
Maximizing Your Production ROI
Maximizing Your Production ROI / Every engineering detail of the GFP / GZZ series gravity filling machine is designed to reduce cleaning time, product loss, and daily maintenance pressure while keeping production efficient.
Cleaner Filling Performance
The GFP series reduces foam through low-vacuum equal liquid level filling and inner-wall flow, helping improve final bottle appearance.
Lower Daily Maintenance Burden
Both series are designed for practical factory use. The GFP series is easy to disassemble and clean, while the GZZ series is easy to operate, clean, and maintain with relatively low maintenance cost.
