Servo Piston Filling Machine Vs Gear Pump Filling Machine
A practical comparison of servo piston filling and gear pump filling for viscosity, accuracy, cleaning, production speed and suitable bottled products.
Send Machine RequirementMain Difference
| Item | Servo Piston Filling | Gear Pump Filling |
|---|---|---|
| Suitable liquid | Medium-to-high viscosity liquid such as detergent, shampoo, lotion, gel and cream-like products | Low-to-medium viscosity liquid such as oil, essence, toner, e-liquid and clean chemical liquid |
| Filling principle | Piston cylinder draws and pushes fixed volume | Gear pump meters liquid by pump rotation |
| Strength | Stable for viscous and foaming products; easy to configure anti-drip nozzles | Compact, accurate and suitable for clean dosing of flowing liquids |
| Not ideal for | Highly corrosive liquid or large particles unless customized | Thick paste, large particles or very high viscosity liquid unless tested |
| Quotation check | Viscosity, filling volume, bottle size, target speed | Liquid compatibility, viscosity, filling volume and pump material |
When To Choose Each Machine
Choose Servo Piston Filling
Use it when the product is detergent, shampoo, lotion, hand soap, gel or other viscous liquid requiring stable volume and anti-drip filling.
Choose Gear Pump Filling
Use it when the product is oil, essence, toner, e-liquid or clean low-to-medium viscosity liquid requiring accurate dosing.
Test Uncertain Liquids
If the liquid is sticky, corrosive, foaming or contains particles, sample testing should be arranged before final machine selection.
Buyer FAQ
Which one is better for shampoo?
Servo piston filling is usually more suitable for shampoo because shampoo is viscous and may require anti-drip filling nozzles.
Which one is better for essential oil?
Gear pump or peristaltic pump filling is usually more suitable for essential oil, depending on accuracy, volume and contact material requirements.
Can gear pump fill cream?
It is not the first choice for thick cream or paste. A piston filling machine is usually more suitable, but sample testing is recommended.
Can both machines connect with capping and labeling equipment?
Yes. Both can work as standalone filling machines or connect with capping, labeling, coding and collecting equipment.
