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

All wetted parts (valves, pistons, hoppers) are CNC-machined from premium 316L stainless steel. The quick-release clamp structure allows seamless connection to your existing CIP (Clean-in-Place) system.

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.

How do I adjust the filling volume when switching bottle sizes?

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.

Will viscous liquids like ketchup drip from the nozzles after filling?

When filling approaches the bottle mouth, we reduce speed and pressure to help prevent splashing and overflow.

What wearing parts need to be replaced, and are they easy to find?

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.

What is the warranty period for this filling machine?

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.

We are located in the United States/Europe. Do you export to our region and does the machine meet local standards?

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.

Our factory operators only speak Spanish/French. Does the Siemens touchscreen support multiple languages?

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.
