Machine Overview

What Is This Machine Used For?

Low Viscosity Filling

12-head gravity filling for low-viscosity liquids

Gravity filling uses the liquid's own weight to flow from a high-level tank. Constant liquid level stabilizes pressure, while timed valves meter the discharge without pressure transfer, helping protect foam-sensitive products.

Liquid And Bottle Compatibility

Low-viscosity Liquid, Bottle And Closure Examples

These examples show low-viscosity, low-foam liquids and common containers suited to gravity filling. The closures represent possible downstream packaging steps.

Water, toner, disinfectant, seasoning and water-like cleaner bottles with separate closures for gravity filling — Actual viscosity, foam level, filling volume, bottle opening and target output determine the tank level, nozzle structure and timed filling settings. Capping requires the matching downstream station.

Method Comparison

Comparison With Other Filling Methods

Filling Method	Best For	Selection Note
Servo Piston Filling	Viscous liquid, detergent, shampoo, lotion	Best for stable accuracy and medium/high viscosity liquids
Gear Pump Filling	Low to medium-viscosity liquid, oil, essence	Better for precision pump dosing
Peristaltic Pump Filling	Clean liquid, reagent, essential oil	Cleaner liquid path and easy tube replacement
Flow Meter Filling	Large-volume low-viscosity liquid	Better for volume metering and larger containers
Rotor Pump Filling	Viscous and flowing products	Better for stable transfer of thicker liquids
Anti-corrosion Filling	Corrosive chemical or agrochemical liquid	Better material resistance

How To Read The Published 12-Head Gravity Filling Machine For Low-Viscosity Liquids Parameters

The website helps shortlist a machine. Final values are released only after the product, container, closure or label, required output and factory conditions are reviewed.

Filling range

Published minimum and maximum volumes are selection references. The actual working range is confirmed with the product and container.

Filling heads

Head quantity describes the installed dosing positions; it does not define output by itself.

Speed basis

A sustained bottles-per-minute target must state filling volume, product behavior, bottle format and line conditions.

Accuracy basis

The measuring method, sample count, tolerance and operating conditions are written into the agreed FAT plan.

Final handover package

After configuration confirmation, the handover package supports installation, operation, maintenance and acceptance without publishing unconfirmed project values.

FAQ

Common Questions Before Buying

What liquid is suitable for gravity filling?

Free-flowing low-viscosity liquids such as alcohol, disinfectant and cleaner are suitable.

Can it fill shampoo?

Not recommended for honey, sauces, creams, pastes or high-viscosity oils; use a piston or rotor-pump solution instead.

Is it easy to operate?

Yes. Gravity filling has a relatively simple structure and is easy to adjust.

Can it be automatic?

Yes. It can be designed as an automatic filling machine and connected with capping and labeling.

Do foaming liquids need special design?

The standard specification is intended for low-foam liquids. Highly foaming products need a separate sample test and special design confirmation.
