GZH Series Automatic Linear Piston Filling Machine
Built for Viscous Liquids with Stable Filling Accuracy and Cleaner Bottle Handling.
Servo-Driven Accuracy: ≤ ±0.5% precision completely eliminates product give-away and maximizes your yield.
Dynamic Anti-Drip: Vacuum suck-back nozzles ensure your bottles and conveyors remain 100% clean.
"No Bottle, No Fill": Integrated Omron sensors prevent massive liquid spills, protecting your equipment.
Tool-Free Changeover: Switch between 100ml and 5000ml bottle formats via touchscreen in under 15 minutes.
High-Performance Linear Piston Filling Technology
The GZH Series automatic linear piston filling machine is built for viscous liquid filling. We use PLC control and servo-driven piston stroke to keep filling stable, accurate and easier to adjust across edible oil, enzyme, syrup, pear paste, suspension liquids, motor oil and daily chemical products.
We supply the GZH Series automatic linear piston filling machine as a standalone filler or as part of a complete liquid packaging line, backed by MotivaPAC’s 20+ years of manufacturing experience, advanced CNC machining capability, ISO 9001 certification and CE certification.
Controlled Filling Near Bottle Mouth
Specially engineered with a vacuum suck-back mechanism, our nozzles guarantee 100% zero dripping. For foaming products like liquid soap, the nozzles feature a diving function (bottom-up filling) to suppress foam generation entirely.
The Solution:Eradicates the industry pain points of sticky sauces dripping onto bottles and conveyors, as well as detergent foam overflowing during high-speed filling.
Servo-Driven Piston Stroke Control
We use servo motors to drive piston stroke, with accurate positioning and fast-to-slow filling control to keep volume output more stable during production.
The Solution: Resolves the unstable filling accuracy of traditional pneumatic cylinders, preventing the costly give-away of high-value materials like essential oils or premium condiments.
Universal Smart Conveyor System
We support a wide filling capacity range, from 30 ml to 5 L, which makes the GZH series linear piston filling machine practical for multi-SKU bottle filling projects.
The Solution:Smoothly handles round, square, or flat bottles (PET, Glass, HDPE) with simple, tool-free adjustments. Perfect for manufacturers with diverse product lines and frequent packaging updates.
316L Stainless Steel & CIP Ready
The Solution:Offers superior corrosion resistance against high-salinity sauces or harsh chemicals, while reducing cleaning downtime during flavor changeovers to under 30 minutes.
Foolproof Operation & Automation
Engineered with advanced sensory and logic control systems to ensure zero-fault operation andmaximum personnel safety.
"No Bottle, No Fill" Interlock
Powered by Omron optical sensors, the machine intelligently pauses dispensing if a bottle is missing or falls over on the conveyor, completely eliminating massive liquid spills.
Siemens PLC Master Touchscreen
A user-friendly HMI allows operators to adjust filling volumes, monitor line speed, and run error-diagnostics digitally on a single screen. No complex mechanical tuning needed.
Auto-Level Control Hopper
The top buffer hopper is equipped with electronic level sensors that automatically communicate with your transfer pump to maintain consistent product pressure and volume.
Maximizing Your Production ROI
Every engineering detail of the GZH series automatic linear piston filling machine is calculated to reduce your operating costs, minimize waste, and accelerate your return on investment.
Minimized Downtime
20-minute tool-free bottle changeovers and CIP cleaning compatibility keep your line running continuously, even when switching across multiple product SKUs and flavors.
Zero Product Waste
The ≤ ±0.5% precision means every drop of your premium olive oil or expensive chemical goes strictly into the bottle, saving thousands of dollars in give-away annually.
Scalable Architecture
Starts as a standalone filler but is engineered to easily synchronize with MotivaPAC’s capping, labeling, and carton packing machines as your business scales up.

Frequently Asked Questions About the GZH Series Automatic Linear Piston Filling Machine
Expert answers to your technical and operational queries.
All adjustments are fully digital. Simply input your target volume (e.g., from 500ml to 1000ml) on the Siemens touchscreen. The PLC will automatically calculate and adjust the servo-motor stroke for the pistons. No mechanical wrenching is required.
When filling approaches the bottle mouth, we reduce speed and pressure to help prevent splashing and overflow.
The main wearing parts are the Teflon piston seals (O-rings). We include a generous set of spare parts with machine delivery. Furthermore, all core components (pneumatics, PLC, sensors) are from globally recognized brands like Siemens, Omron, and AirTAC, making local replacement sourcing very easy.
We offer a standard 12-month warranty on the entire machine, covering all non-consumable parts. We also provide lifetime online technical support, video troubleshooting, and dispatched engineer services for overseas installations upon request.
Yes. We have over 20 years of manufacturing history and has successfully exported packaging machinery to the USA, UK, Germany, Australia, and over 30 other countries. The GZH series is fully CE Certified and manufactured under the ISO 9001 quality management system, ensuring strict compliance with North American and European industrial standards.
Absolutely. The Siemens HMI touchscreen can be programmed in bilingual or multilingual interfaces (e.g., English/Spanish, English/French) to ensure smooth and error-free operation by your local staff.
