Machine Overview

What Is Gear Pump Filling Machine Used For?

Precision Pump Filling

Accurate gear-pump dosing across compatible liquid products

Gear pump filling uses a gear pump system to control liquid transfer and filling volume. The pump, seals, hoses and nozzles are selected after reviewing the actual liquid viscosity, foaming behavior, chemical compatibility and cleaning requirements.

Liquid And Package Compatibility

Representative Container And Closure Examples

Gear pump dosing can be configured for oils, essences, e-liquids, liquid fertilizer, detergent, shampoo and other compatible low- to medium-viscosity liquids in small or medium containers.

Essential oil, e-liquid, fragrance essence, cosmetic toner and chemical liquid bottles with separate closures for gear pump filling — Actual liquid viscosity, chemical compatibility, target dose and bottle opening determine the pump material, tubing and filling nozzle.

Essential oil
Essence
E-liquid
Liquid fertilizer
Detergent
Shampoo
Toner
Low-viscosity chemical liquid
Fragrance liquid

Machine Configurations

Gear Pump Filling Machine Configurations

Each configuration has its own filling range, suitable products and output conditions. In particular, the 8-head servo example lists 50–5000 mL and 1–30000 mPa·s; its 40–45 bottles/min reference is based on 50–500 mL medium-viscosity daily chemical or sauce products. It is not a speed guarantee across the full volume and viscosity ranges. Confirm the actual formula, bottle and connected equipment before selecting a configuration.

Engineering Definitions

How To Read The Published Gear Pump Filling Machine 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.

FAQ

Common Questions Before Buying

What products can a gear pump filling machine handle?

Gear pump filling can be configured for oil, essence, e-liquid, liquid fertilizer, detergent, shampoo and compatible low- to medium-viscosity chemical liquids. Final pump, seal, hose and nozzle selection is confirmed from the actual product and required cleaning process.

Is it suitable for thick lotion?

Thicker lotion or paste needs a project-specific review. The 8-head servo gear-pump configuration on this page lists gel and cream applications, but this does not apply to every gear-pump configuration. Compare servo piston or rotor pump filling where appropriate, and confirm suitability through product testing.

Can the pump material be customized?

Yes. Pump and contact material can be selected according to the liquid property.

Can it connect with capping and labeling machines?

Yes. It can be integrated into a complete filling capping labeling line.

Can you test with our liquid sample?

Yes. Liquid and bottle samples can be tested before final configuration.

Buyer Selection Guide

Gear Pump Filling Machine Selection Answers For Buyers

Best Used For

Essential oil, e-liquid, toner, fragrance, light oil, chemical liquid and other clean low-to-medium viscosity products.

When To Choose It

Choose this machine when the product is not too thick, does not contain large particles and needs accurate pump metering for small or medium bottle volumes.

Not Recommended For

Do not assume every configuration can handle thick cream or paste. Review the 8-head servo example separately and confirm the actual product by sample testing. Liquids with particles or incompatible chemistry also require a project-specific review.

Before Quotation

Liquid name, viscosity, filling volume, bottle mouth diameter, target speed, material compatibility requirement and cleaning requirement.

More Compatible Bottle Formats

Daily chemical, fertilizer and lubricant containers

Gear pump filling is not limited to the small bottles shown above. The same machine family can be configured for compatible shampoo, detergent, liquid fertilizer, chemical liquid and lubricant containers after the actual product and package are reviewed.

Shampoo and personal care bottle example for gear pump filling — **Shampoo And Personal Care**Flip-top or pump bottle

Handled detergent bottle example for gear pump filling — **Detergent Bottle**Handled HDPE container

Liquid fertilizer and compatible chemical jerrycan example for gear pump filling — **Liquid Fertilizer And Chemical**Jerrycan with screw closure

Lubricant oil bottle example for gear pump filling — **Lubricant And Oil**Handled oil bottle

Representative containers only. Final pump material, seals, hoses, nozzle, filling range and line configuration are confirmed from the actual liquid, viscosity, bottle opening, target volume, cleaning requirement and required output.
