Before Selecting a Machine

These details determine the filling method and pump configuration.

01
Liquid Properties

Viscosity, fluidity, foaming, particles and temperature.

02
Filling Volume

Minimum and maximum volume required for each container.

03
Container Details

Bottle, jar or pouch dimensions and opening size.

04
Production Output

Required containers per minute and automation level.

Product samples and container photos are recommended for pump, nozzle and filling-accuracy evaluation.

LIQUID FILLING MACHINE GUIDE

How to Select a Liquid Filling Machine

The right liquid filler depends on more than filling volume. Viscosity, foaming behavior, product compatibility, container type, filling accuracy and required output should be evaluated together before selecting a pump and machine configuration.

01

Key Selection Factors

Five details that affect filling performance, pump selection and production efficiency.

01

Liquid Properties

Confirm viscosity, fluidity, foaming, particles and operating temperature.

02

Filling Volume

Provide the minimum and maximum volume required for each container.

03

Container Details

Bottle, jar or pouch dimensions and opening size affect nozzle and handling design.

04

Required Accuracy

Accuracy requirements help determine the pump, controls and filling method.

05

Production Output

Required containers per minute determine nozzle quantity and automation level.

02

Compare Liquid Filling Systems

Different pump and metering systems are suited to different liquid properties and production requirements.

Filling System Suitable Products Typical Advantages Selection Notes
Magnetic Pump Filler Free-flowing, low-viscosity liquids Compact liquid path and convenient digital adjustment Pump material must be compatible with the actual product
Peristaltic Pump Filler Small-volume liquids requiring a controlled liquid path Product mainly contacts the filling tube Tube material, service life and product compatibility matter
Piston Filling Machine Low- to medium-viscosity liquids and selected fluid products Volumetric filling and a broad configurable filling range Cylinder size should match the required filling-volume range
Flowmeter Filling Machine Continuous automatic liquid filling applications Electronic metering and convenient recipe adjustment Flowmeter type should match the liquid characteristics
Gravity Filling Machine Free-flowing and low-viscosity products Relatively simple structure for suitable applications Product flow and tank-head conditions should remain stable

AUTOMATION SELECTION

Choose the Right Automation Level

Machine automation should match your required output, available labor, product-change frequency and plans for packaging-line integration.

A higher automation level does not automatically mean a better choice. Production volume and changeover requirements should be considered together.

01

Tabletop Filler

Compact equipment for laboratories, sampling and small-volume production.

02

Semi-Automatic Filler

Flexible filling with manual container placement and collection.

03

Automatic Inline Filler

Continuous conveying and multi-nozzle filling for higher output.

04

Complete Filling Line

Integrated filling, capping, labeling and product-collection system.

03

Typical Liquid Filling Applications

Final machine suitability should be confirmed using the actual product properties and packaging container.

Food & Beverage

Water, juice, milk, cooking oil, vinegar and fluid food products.

Cosmetics

Toner, serum, essential oil, fragrance and personal-care liquids.

Pharmaceutical Liquids

Oral liquids, syrups, drops and other compatible liquid products.

Household Products

Detergents, cleaning liquids and other household formulations.

04

Sample Evaluation Process

Product and container testing helps confirm filling performance before the machine configuration is finalized.

01

Submit Details

Send product information, filling volume, containers and output target.

02

Method Evaluation

Evaluate the pump, metering method, nozzles and liquid-contact parts.

03

Sample Testing

Test filling accuracy, speed, foaming and dripping when possible.

04

Solution Confirmation

Confirm the machine model, nozzle quantity and optional equipment.

06

Frequently Asked Questions

Common questions about liquid filling methods and customization.

Can one filling machine handle different liquids?
It may be possible when the products have compatible properties and the pump, tubing, seals and nozzles are suitable. Cleaning, cross-contamination and changeover requirements should also be evaluated.
Which pump should I choose for my liquid?
Pump selection depends on viscosity, filling volume, accuracy, foaming behavior, particles, product compatibility and required output. Product information or a sample is recommended.
Can the machine fill foaming liquids?
A suitable configuration may use adjustable filling speed, diving nozzles or bottom-up filling. Testing with the actual product is recommended before final configuration.
Can the machine handle different bottle sizes?
Many machines can be adjusted for several container sizes within the designed range. Different openings or major shape differences may require nozzle, guide-rail or bottle-handling adjustments.
Can the number of filling nozzles be customized?
Yes. Nozzle quantity can be selected according to filling volume, filling time, container spacing and the required production output.
Can the filler connect with capping and labeling machines?
Yes. Automatic fillers can be integrated with bottle feeding, capping, sealing, labeling, coding, inspection and finished-product collection equipment.
