Choose By Liquid And Production Requirement

Viscous Or Foaming Liquid

Servo piston filling is usually selected for detergent, shampoo, lotion, liquid soap, gel and medium-to-high viscosity products.

Low-To-Medium Viscosity Liquid

Gear pump filling is suitable for oil, essence, toner, e-liquid and clean chemical liquid when accurate dosing is required.

Small Bottle Or Clean Dosing

Peristaltic pump filling is often used for small-volume liquid where the liquid only contacts the hose.

Corrosive Liquid

Anti-corrosion filling should be considered for pesticide, disinfectant or chemical liquid that may react with standard stainless steel contact parts.

High-Speed Continuous Line

Tracking filling can reduce bottle stopping time and is suitable when higher output or smoother line movement is required.

Custom Bottle Line

When the line also needs capping, labeling and coding, filling method should be selected together with the complete line layout.

Buyer FAQ

What information is needed before quotation?

Bottle size, bottle shape, liquid type, viscosity, filling volume, target speed, cap type, label size and factory voltage should be provided.

Can one filling machine handle different bottle sizes?

Yes, many machines can be adjusted for different bottle sizes, but the adjustment range depends on bottle height, bottle diameter, filling volume and conveyor layout.

Is the actual speed always the same as the listed speed?

No. Actual speed depends on filling volume, liquid viscosity, bottle size, number of filling heads and whether the machine connects with capping and labeling equipment.

Should samples be tested before production?

For viscous, foaming, corrosive or unusual liquids, sample testing is recommended before final machine configuration.
